Sierra Sage salon

Balayage is a hand-painting technique where your colorist applies lightener freehand onto sections of your hair rather than using foils. The word comes from the French term meaning to sweep, and that is exactly what it looks like — the colorist sweeps color onto the surface of your hair in graduated strokes, concentrating more lightener toward the ends and less toward the roots. The result is a soft, natural-looking dimension that mimics the way hair lightens from sun exposure over time, which is why stylists call it lived-in color.

At Sierra Sage Salon on La Mesa Boulevard, Courtney Salois specializes in this technique because it works particularly well in San Diego’s climate. Clients who spend time outdoors — walking Lake Murray, hiking below Mt Helix Park, or just running errands in La Mesa Village — get a color that blends with their natural sun exposure rather than fighting it. The hand-painted approach means no two balayage applications look the same, and the grow-out is gradual rather than creating a harsh line at the root.

Balayage works on most hair types, lengths, and base colors. It tends to look best on hair that is at least shoulder length because the gradient effect needs room to develop. Clients with very short hair or those who want dramatic root-to-tip brightness may get better results from traditional foil highlights, which Honey & Hive and several other La Mesa salons also offer. Sierra Sage provides free consultations so you can see what the technique would look like on your specific hair before committing. Text 619-971-4237 to set one up.

The core difference is how the color is applied. Balayage is painted on by hand in sweeping strokes, creating a soft, blended transition from darker roots to lighter ends. Traditional highlights use foils — your stylist sections out individual strands, applies lightener from root to tip, and wraps each section in foil to process. The foil method creates uniform, evenly spaced ribbons of color. The hand-painting method creates a more organic, sun-kissed effect.

The practical differences matter for your wallet and your calendar. Highlights tend to create a more noticeable regrowth line within four to six weeks because the color starts at the root. Balayage grows out more gracefully — most clients at Sierra Sage Salon go eight to sixteen weeks between appointments because the blended root area does not create a hard line of demarcation as it grows. Over the course of a year, that can mean two or three balayage sessions versus five or six highlight appointments. Partial highlights at Sierra Sage start at $225 and full highlights start at $285. A full balayage starts at $335 but typically requires fewer annual visits.

Neither technique is objectively better — it depends on what you want. If you are looking for bright, defined strands with strong contrast and you do not mind more frequent maintenance, traditional highlights are the right call. If you want something that looks like you just spent a week at the beach and you prefer longer stretches between appointments, balayage is the move. Courtney can also combine both techniques in a single session — using foils around the face for brightness and hand-painting the rest for dimension — which is sometimes called a foilayage or hybrid approach.

A partial balayage at Sierra Sage Salon costs $285 and takes approximately two hours. This covers the top of the head and face-framing pieces — the areas most visible when your hair is down. A full balayage starts at $335 and takes about two and a half hours, covering all sections for complete, all-over dimension. Both services include a toner application to refine the final shade and neutralize any unwanted warmth.

If you want a face-frame highlight — sometimes called a money piece — without a full balayage session, that service is $200 and takes about an hour and a half. It brightens the pieces around your face without touching the rest of your hair, which makes it a good option if you are not ready for a full color investment or if you want to add brightness between full balayage appointments. A toner or gloss refresh on its own is $95 and takes about an hour.

How the price compares to other La Mesa salons depends on the stylist’s experience level and the salon’s positioning. Boutique salons along La Mesa Boulevard in the Village — including Scisters Salon & Apothecary, Calla Hair Studio, and Sierra Sage — tend to charge more than chain salons at Grossmont Center but less than luxury salons in coastal neighborhoods like La Jolla or Del Mar. Sierra Sage offers free consultations so you know the exact cost for your specific hair before you book.

Most balayage clients can go three to four months between full touch-up appointments, and some stretch it to five or six months depending on how subtle the color placement is. That is one of the biggest advantages of the technique — because the color is concentrated on the mid-lengths and ends rather than starting at the root, the grow-out pattern looks intentional rather than neglected.

The toner applied at the end of your balayage session typically lasts six to eight weeks before it starts to fade, which is when most clients notice a shift toward brassiness. A gloss or toner refresh at Sierra Sage Salon is $95 and takes about an hour. That one appointment can extend the life of your balayage by another month or two without re-lightening, which saves both money and hair integrity.

Several factors affect how long your specific balayage lasts. Coarser hair textures tend to hold color longer. Clients who wash less frequently — two to three times per week rather than daily — maintain their tone longer. Sun exposure, chlorine from swimming, and hot water all accelerate fading. In La Mesa, where the sun is a factor nearly year-round, UV-protective hair products are not optional — they are the single biggest thing you can do between appointments to keep your color from shifting.

The most impactful change most clients can make is switching to a sulfate-free shampoo. Sulfates are the aggressive detergents that create the foamy lather in most drugstore shampoos, and they strip color molecules from your hair every time you wash. A sulfate-free, color-safe shampoo cleans your hair without pulling out the tone your colorist worked to create. Wash two to three times per week rather than daily, and use lukewarm water — hot water opens the cuticle and lets color escape faster.

Purple shampoo is the other essential product for anyone with blonde or light balayage. It neutralizes the yellow and orange tones that build up over time by depositing a small amount of violet pigment. Use it once a week, leave it on for three to five minutes, and follow with a hydrating conditioner. For brunette balayage or caramel tones, a blue shampoo works the same way by neutralizing orange rather than yellow.

Deep conditioning once a week keeps lightened hair from becoming dry and brittle. A weekly mask or deep conditioner — applied from mid-length to ends, left on for ten to fifteen minutes — rebuilds moisture and keeps your balayage looking healthy. Heat protectant before any blow-drying, flat ironing, or curling is non-negotiable. Courtney recommends professional-grade products and can give you a specific product list during your appointment at Sierra Sage.

Tape-in extensions are thin wefts of hair with a medical-grade adhesive strip on one side. Your stylist sections your natural hair into thin layers, sandwiches a small section between two adhesive weft strips, and presses them together. The result is a flat, lightweight bond that sits close to the scalp and blends with your natural hair to add length, volume, or both. The entire installation process typically takes sixty to ninety minutes.

At Sierra Sage Salon, tape-in extension installation starts at $300. The hair itself is not included in that price — you will either purchase hair through the salon or bring your own. Courtney requires a consultation at least 48 hours before your first extension appointment to assess your hair, discuss your goals, and determine exactly what you need.

Tape-ins need to be moved up every six to eight weeks as your natural hair grows. The removal process involves dissolving the adhesive with a professional solvent, which Sierra Sage charges $175 for. Good-quality tape-in wefts can be reused two to three times before they need to be replaced, which means your initial hair investment can last through multiple move-up cycles.

The difference comes down to how the extensions attach to your natural hair. Tape-in extensions use adhesive strips that sandwich a thin section of your hair between two wefts. Hand-tied weft extensions use a completely different foundation — your stylist creates a row of tiny beads along a section of your hair, then sews a hand-tied weft directly onto that beaded row. No glue, no tape, no heat.

Hand-tied wefts sit flatter against the head and are generally more comfortable for extended wear. They last longer between adjustments — eight to twelve weeks compared to six to eight for tape-ins — and the wefts themselves can be reused for six to twelve months. Tape-ins are faster to install, cost less upfront, and work especially well on fine to medium hair.

Sierra Sage Salon offers both methods. Tape-in installation starts at $300. Habit hand-tied weft extensions are $200 per full row and $160 per half row. Other La Mesa salons that specialize in extensions include Radiance and Honey Luxe Salon — Sierra Sage’s differentiator is Courtney’s hand-tied weft training and her approach to matching extension density to your natural growth pattern.

Extension pricing at Sierra Sage Salon breaks down by method and quantity. Tape-in extension installation starts at $300. Habit hand-tied weft extensions are $200 per full row and $160 per half row. Per weft 22-inch extensions are $160. Extension coloring starts at $100. Tape-in removal is $175. A free 15-minute consultation is required before your first extension appointment.

The total cost depends on how much hair you need. A client adding volume with two rows of hand-tied wefts is looking at $400 for installation plus the cost of the hair. A client going from short to long with four rows and a full color match is looking at $800-plus for the service. The hair itself varies — budget $200 to $600 depending on length and quality.

Over a year, extensions are a significant investment — most clients spend $1,500 to $3,000 annually including maintenance — but the alternative of achieving the same length and volume through natural growth could take years. Courtney will give you the exact total during your consultation so there are no surprises.

Tape-in extensions need to be moved up every six to eight weeks. The adhesive loosens as your natural hair grows, and the bonds shift away from the scalp. Quality tape-in wefts can be reused two to three times. Hand-tied weft extensions last eight to twelve weeks between adjustments, and the wefts can be reused for six to twelve months with proper care.

Brush your extensions with a loop brush at least twice a day, starting from the ends and working up. Never sleep with wet hair — braid it loosely before bed to prevent matting. Avoid oil-based products near tape-in bonds because oil dissolves adhesive.

Swimming requires extra care. Wet your hair with fresh water before getting in the pool or ocean, apply a leave-in conditioner, and rinse thoroughly afterward. Courtney recommends braiding extensions before swimming to minimize tangling. The San Diego beach lifestyle is fully compatible with extensions — most Sierra Sage clients surf, swim, and hike without issues — but it does require attention.

A money piece is a section of highlighted hair that frames your face — typically the pieces on either side of your part that fall forward when your hair is down. These face-framing highlights are the most visible part of any color job and have the highest impact on how your overall look reads. A well-placed money piece can brighten your complexion and draw attention to your eyes without requiring a full balayage or highlight session.

At Sierra Sage Salon, a face-frame highlight costs $200 and takes about an hour and a half. Courtney lightens the pieces around your face and applies a toner to get the exact shade you want — anything from a subtle caramel on brunette hair to a bright platinum frame on darker bases. This service works particularly well as a standalone appointment between full balayage sessions.

The money piece also works as a first step for clients who have never colored their hair and want to test the waters without a full commitment. It is a relatively fast, lower-cost way to see how you feel about lighter pieces before deciding whether to go further with a partial or full balayage.

Vivid color refers to any shade outside the natural spectrum — mermaid teals, electric blues, deep purples, rose golds, fiery coppers, and neon pinks. These colors use direct-dye formulas that deposit pigment onto the hair’s surface rather than penetrating the cortex.

At Sierra Sage Salon, vivid hair color starts at $110 per hour and typically requires a three-hour appointment. If your hair is already pre-lightened to a pale blonde, the vivid color can go on in a single session. If you are starting from dark hair, you will need one or more lightening sessions first. Courtney requires a consultation at least 48 hours before any vivid color appointment.

Vivid colors fade faster than traditional permanent color because direct dyes sit on the surface. Most vivid colors last three to six weeks before significant fading. Sulfate-free shampoo, cold water rinses, and minimal washing extend the life of vivid color significantly. Courtney can also mix custom shades and formulate your color to fade in a flattering direction rather than turning muddy.

UV exposure is the single biggest accelerant of color fading, and La Mesa, California gets an average of 266 sunny days per year. If you have balayage, highlights, or vivid color, the sun is working against your investment every time you step outside. UV radiation breaks down color molecules the same way it fades fabric and paint.

A leave-in conditioner or styling product with UV protection creates a barrier between your hair and the sun. Apply it every morning. If you are spending extended time outdoors — hiking Mt Helix Park, walking the trails around Lake Murray, or spending a Saturday at the La Mesa Village Farmers Market — a hat does more than any product can.

After sun exposure, rinse your hair with fresh water. If you swam in a pool, rinse immediately — chlorine reacts with lightened hair and can create a greenish cast on blonde tones. Courtney recommends a specific set of products to her clients based on their color and hair type during appointments at Sierra Sage.

Come with clean, dry hair that has not been freshly washed that day. Ideally, wash your hair the night before — you want it free of heavy product buildup but not stripped of its natural oils. Avoid applying any styling products the morning of your appointment.

Bring reference photos. This is the single most useful thing you can do to help your colorist understand what you want. Screenshots from Instagram or Pinterest give Courtney a visual target. Be aware that the same technique can look completely different on different base colors, hair textures, and lengths — so bring photos of people whose starting point is similar to yours. Courtney’s Instagram at @sierrasagesalon and @Hairbycourtneysalois have examples of her actual work.

If this is your first time at Sierra Sage, book a free consultation before your color appointment. The consultation takes about fifteen minutes and gives Courtney a chance to evaluate your hair’s condition, discuss realistic expectations, and map out a plan. Some hair — particularly hair that has been previously box-colored or heavily processed — may need a different approach than virgin hair.

The answer depends entirely on the type of color service. A root touch-up for single-process color needs attention every four to six weeks. Highlights need refreshing every six to ten weeks. Balayage can go eight to sixteen weeks between full sessions, with an optional toner refresh at the six to eight week mark.

At Sierra Sage Salon, a root touch-up is $120, a toner or gloss refresh is $95, and a partial balayage is $285. One strategy Courtney uses with her clients is alternating between full and partial services throughout the year. That rotation keeps your color looking fresh while spacing out the heavier appointments and keeping the total annual cost manageable.

If you are coloring your hair for the first time and not sure how much maintenance you want to commit to, start with a money piece or partial balayage rather than a full transformation. That gives you a sense of how the grow-out looks on your hair and whether you are comfortable with the schedule before going further.

A keratin treatment coats your hair with a layer of keratin protein — the same protein your hair is naturally made of — that fills in gaps in the cuticle layer and smooths the hair shaft. The result is reduced frizz, less curl, faster blow-dry time, and a sleeker texture that lasts eight to twelve weeks. It does not permanently straighten your hair — it relaxes the texture so your natural pattern is softer and more manageable.

At Sierra Sage Salon, keratin treatments start at $300 and take approximately three hours. You cannot wash your hair or pull it back for 48 to 72 hours after the treatment — the keratin needs time to fully bond with the hair shaft.

Keratin treatments work particularly well in San Diego’s coastal humidity. Even in La Mesa, which sits inland, the marine layer pushes moisture through the area that can cause frizz in textured hair. If you spend ten minutes every morning fighting your hair with a flat iron, a keratin treatment could cut that routine in half and reduce heat damage in the process.

Courtney Salois is the owner and lead stylist at Sierra Sage Salon. She is a San Diego native who has been behind the chair since 2015, giving her over a decade of professional experience. She opened Sierra Sage to build a women-owned, LGBTQ+-affirming studio where stylists and clients could be themselves.

Her technical specialty is lived-in color — balayage painted to mimic the way hair naturally lightens from sun exposure, with soft transitions that grow out gracefully. On the extensions side, Courtney is trained in the Habit hand-tied weft method and also installs tape-in extensions, giving her clients two options depending on their hair type and lifestyle.

Carlos Netro is the other stylist at Sierra Sage, bringing a focus on inclusive, budget-conscious service. Between the two of them, Sierra Sage covers a range from creative vivid color work to everyday maintenance cuts and root touch-ups.

La Mesa has a deep bench of salons. Millicent and Company has been in the community for over 30 years. Honey & Hive won the 2025 Best of La Mesa award. Scisters Salon & Apothecary is a Village institution. Chain salons at Grossmont Center offer quick-turn, budget-friendly options. The La Mesa Boulevard salon corridor runs from Calla Hair Studio at 8803 down to The Village Hair Salon closer to the heart of the Village.

What Sierra Sage offers is a tight, two-stylist boutique with a specific technical focus. This is not a full-service salon that does a little of everything. It is a studio built around three specialties — balayage, extensions, and vivid color — run by a stylist who chose those disciplines because they are what she does best.

The vibe is closer to walking into a friend’s studio than checking into a production-line salon. If you value that kind of experience, Sierra Sage is built for you.

Yes. Sierra Sage Salon identifies as LGBTQ+-affirming and as a transgender safespace. These are not just labels — they reflect how Courtney Salois built the salon from the ground up. She created Sierra Sage specifically as a space where every client is welcome regardless of gender identity, expression, or orientation.

For transgender and nonbinary clients, this matters practically as well as culturally. Hair is deeply personal, and for clients navigating a transition, finding a stylist who understands their goals without requiring a lengthy explanation is important. Courtney approaches every consultation the same way — what do you want your hair to do for you, what does your maintenance life look like, and what is realistic given your starting point.

The La Mesa salon community overall is welcoming, but not every salon explicitly signals safety for LGBTQ+ clients the way Sierra Sage does. If this matters to you, it is worth knowing that the signal is intentional and backed by the way the business actually operates.

Sierra Sage Salon is at 8749 La Mesa Boulevard, La Mesa, California 91942 — on La Mesa Blvd in La Mesa Village. The salon sits down the hill from Mt Helix Park in the eastern stretch of the Village. Calla Hair Studio is next door at 8803. If you are coming from the western end of the Village, you will pass Farmer’s Table, Swami’s Cafe, and Mario’s de La Mesa on your way up the boulevard.

Parking is free on the street and typically easy to find. Friday afternoons are busier because of the La Mesa Village Farmers Market, which shuts down part of La Mesa Boulevard weekly. The salon is also accessible from Jackson Drive, which connects to the Grossmont area.

For clients driving from outside La Mesa, the salon is roughly ten minutes from the I-8 freeway. From the Mt Helix residential area, it is a straight drive down the hill. Grab coffee at The AubreyRose Tea Room or lunch at Brigantine Seafood & Oyster Bar before or after your appointment.

The fastest way to book is to text 619-971-4237. Courtney manages her schedule directly through text — no call center, no front desk, no automated phone tree. You can also call the same number or book online through Sierra Sage’s Square booking page at sierrasagesalon.com. Online booking shows real-time availability and lets you select your service and choose your stylist.

For first-time clients, Courtney recommends booking a free consultation before your first color or extension appointment. The consultation takes about fifteen minutes and can be done in person or by text with photos. This step lets Courtney evaluate your hair’s condition, discuss your goals, and give you an accurate price estimate.

For color, extensions, and keratin treatments, booking at least a week in advance is recommended — Courtney’s balayage and extension slots tend to fill up, especially on Thursdays and Fridays. The salon is open seven days a week: Sunday and Monday 10 AM to 6 PM, Tuesday through Thursday 9 AM to 8 PM, Friday and Saturday 9 AM to 6 PM.
