Color specialist Helen Hernandez runs Hair by Helen from The Boulevard Salon at 6512 El Cajon Boulevard in College Area, San Diego, bringing a career that spans more than three decades across the city and Central America. Hernandez built her early clientele in the SDSU College Area, then spent 14 years owning and managing a salon in Costa Rica before returning to reopen as an independent booth renter. Her technical focus lands on all-over single-process color, balayage, foil highlights, color correction, and root touch-ups, alongside Brazilian Blowout certification and keratin smoothing treatments. Clients preparing for formal occasions coordinate alterations at Susie Thai Alterations on the same El Cajon Boulevard corridor, pairing garment fitting with a blowout or updo in a single trip. Round-brush blowouts and Olaplex bond-repair treatments fill the maintenance side of the menu, keeping color-treated hair structurally intact between appointments. The 92115 ZIP anchors the salon on the stretch of El Cajon Boulevard closest to the SDSU Transit Center, putting it within two trolley stops of campus. Hernandez cuts both men's and women's hair, with conditioning treatments calibrated to the hard-water mineral load that the tap supply deposits on processed strands. Walk-in availability is limited — most services run by appointment to allow full color-processing time. Tension-release clients round out a visit at Knots in Knead on El Cajon Boulevard for a post-color scalp and shoulder reset. The salon accepts cryptocurrency alongside standard card payment, an unusual processing option for a single-chair studio on the boulevard.
