Holly Van Duren Salon in Alpine occupies a private suite inside the Head East building on Arnold Way, specializing in balayage, tape-in extensions, and precision cutting shaped by more than 19 years behind the chair. Certifications span every major extension-installation method — K-tip fusion, hand-tied weft, and tape-in — plus keratin smoothing, a technical range that parallels the scalp-and-skin revision work at Nourished Living Spa Skin and Scalp Therapy on Alpine Blvd. A decade-long tenure managing a Del Mar salon preceded the move to Alpine, bringing coastal color techniques to the East County market. Mobile appointments extend the studio's reach beyond the Arnold Way commercial pocket, serving bridal parties and on-location styling across the Alpine Blvd corridor where Chic Boutique outfits the same event-day clientele. The most complex bookings involve full-head highlight corrections paired with 20-inch tape-in extension installations, a multi-session process requiring strand-by-strand color matching under controlled lighting.
