Radiant Retwists in College Area is a loc-specialist studio at 7283 El Cajon Boulevard, San Diego 92115, offering retwists, two-strand twists, barrel twists, and loc maintenance by appointment through Booksy. The studio sits on the eastern stretch of El Cajon Boulevard roughly two miles east of SDSU, in a commercial corridor where personal-care and international dining businesses line the boulevard's frontage between College Avenue and the La Mesa border. Retwist sessions run approximately two and a half hours and include a scalp cleanse, re-parting, and palm-roll or interlocking technique depending on loc maturity and client preference, with extension fiber and braiding supplies sourced from beauty-supply retailers on the same corridor including Sam's Beauty Outlet on University Avenue. Two-strand twist sets and barrel-twist styles run three to three and a half hours and work on both starter locs and mature locs with established root patterns. The operator also handles loc detox treatments that strip product buildup from the interior shaft using an apple-cider-vinegar soak and baking-soda clarifying rinse. The 92115 ZIP anchors the studio to the College Area sub-community, and the El Cajon Boulevard corridor's density of grooming operations — including barbers at Habibi Cut further west — reflects the neighborhood's concentration of textured-hair and natural-hair services near the SDSU campus. Walk-in availability is limited, and the studio recommends advance booking for all loc services.
