'Do Beauty Boutique in College Area is a stylist-owned color and cutting studio at 5935 El Cajon Blvd, San Diego 92115. Owner Tiffany Schaaff founded the salon in 2017 after building a 25-year career split between Chicago and San Diego, including seven years as an international platform artist and educator for Rusk and Babyliss Pro. The salon sits on the same El Cajon Blvd grooming corridor as Boulevard Barbers, anchoring a personal-care cluster five blocks east of SDSU that serves campus staff, students, and the surrounding residential blocks. The service menu spans balayage, ombré, fashion color, smoothing treatments, perms, and special-occasion updos — each technique taught at industry trade shows before reaching this chair. Color-correction sessions bill at $400 for the first four hours and $125 per additional hour, pricing that reflects the chemical precision required to strip box-dye buildup and rebuild tone without structural breakage. Women's cuts start at $95 and men's at $55, both including a shampoo and blowdry finish calibrated to each client's density and texture. Conditioning treatments target the accelerated cuticle erosion that inland San Diego humidity patterns inflict on color-treated hair, using bond-repair formulations applied between foil sets. Clients booking highlight or balayage sessions often schedule nail appointments at Nail's Paradise and Spa in the same 92115 ZIP. The retro-themed interior — vintage signage, mid-century light fixtures — sets a visual tone distinct from the strip-mall norm along this stretch of boulevard. Full-head fashion colors range from pastel overlays to high-contrast vivids, using developer volumes matched to each client's starting level and porosity across a consultation process Schaaff built from two decades of corrective work.
