Reina Eyebrows & Facial Threading in San Carlos specializes in precision brow shaping at 8680 Navajo Rd, Suite 101, San Diego, 92119, anchoring a small commercial plaza on the Navajo Road corridor between Lake Murray and the Cowles Mountain trailhead. The studio's primary technique is cotton-thread epilation, applied to eyebrows, upper lip, chin, forehead, sideburns, and full-face zones, with the thread twisted at variable tension angles to extract individual follicles cleanly without pulling on surrounding skin. The Navajo Road strip clusters several personal-care studios in the same block, including Navajo Spa, which runs massage and bodywork services from a storefront steps away. Microblading services run at a $600 session fee that includes the initial application and a complimentary touch-up within eight weeks, using a manual hand tool to etch hair-stroke pigment into the brow dermis for semi-permanent definition that lasts 12 to 24 months depending on skin type and sun exposure. Brow lamination uses a keratin-based solution to redirect hair growth upward into a feathered, fuller silhouette, and eyebrow tinting adds vegetable-dye color to sparse areas between threaded hairs. The technician speaks English, Persian, and Turkish, serving the multilingual clientele that characterizes San Carlos and the broader east San Diego corridor. Navajo Road funnels weekend foot traffic from Cowles Mountain hikers heading south toward Lake Murray Boulevard, and the studio's walk-in policy accommodates impulse appointments from the trailhead crowd. San Diego's east-county threading market is concentrated in a handful of dedicated brow studios, and Reina's single-service focus on thread-based epilation and microblading distinguishes it from full-menu salons that fold threading into a broader waxing or facial program. Scalp and body acupuncture at On Point Acupuncture and Wellness Center draws from the same San Carlos wellness corridor, and many clients combine skincare precision work with traditional medicine appointments on the same trip down Navajo Road. The studio takes Visa, MasterCard, American Express, Discover, debit, and cash, with free lot parking at the door.
