For combined hair, spa, and boutique shopping in downtown San Diego, Salon De Marcus at Second Avenue and G Street blends color services, facial treatments, waxing, and men's and women's retail in one storefront. The color bar stocks Pureology, Bumble and Bumble, Paul Mitchell, Global Keratin, and Moroccan Oil for post-service maintenance, supplying take-home care for everything from keratin smoothing to full highlights — a product depth that complements the salon-grade lacquer selection at LV Nails Spa in the Gaslamp Quarter. Extensions, corrective color, and Global Keratin smoothing treatments fill out the technical menu, while the integrated clothing section converts the space into a combined retail and styling destination. All stylists cross-train in a unified cut-and-color methodology so any available chair delivers a consistent result, and the in-house boutique adds a head-to-wardrobe coordination layer that aligns with the bespoke garment work at B Street Tailoring and Cleaners. The salon's most intensive service involves Global Keratin's formaldehyde-free smoothing system, which restructures disulfide bonds through controlled aldehyde chemistry to reduce frizz and cut blow-dry time by up to 40 percent on coarse and curly textures.
