OB Waves Salon has operated on Voltaire St since 2013 under owner Erica Hartman, a former L'Oreal Professionnel educator whose 20-plus-year book of business anchors a women-owned team specializing in custom color, curly-hair cuts, and the signature beach-wave perm. The color program runs demi, semi, and permanent single-process work alongside full and partial highlights, babylights, and French-inspired balayage, which sends the lash-and-brow side of a pre-event transformation over to Total Beauty Bar. The beach-wave perm is the salon's most distinct offering, a cold-wave technique tailored for the laid-back Ocean Beach aesthetic rather than tight traditional curl sets. Men's cuts are booked with stylists who cross-train in barbering and scissor work, widening the service range beyond typical women-only salon formats. The team coordinates blow-dries and updos for weddings on the Sunset Cliffs coastline, often pairing the hair appointment with post-event recovery bodywork at Massage By Noel. The most technical work on the calendar is curly-hair custom coloring, which requires pattern-preserving dry sectioning and a painted color application rather than foil-heavy volume to avoid flattening the curl.
