California's only salon exclusively dedicated to non-toxic keratin treatments, Smoothed Salon at 3436 30th St operates as a women-owned business in North Park's 92104 ZIP code. Clients preparing for smooth, frizz-free results often pair their keratin session with body waxing at Gingerly Wax beforehand. The salon stocks 10 to 20 formaldehyde-free keratin brands simultaneously, matching each formula to the client's specific hair texture, density, and porosity. Nail finishing at Twinkle Nails & Spa 2 rounds out a full event-prep day for clients booking both appointments back to back. The open-air salon layout ventilates chemical vapors during application, and bilingual stylists conduct consultations in both English and Spanish. The team handles multi-texture households where straight, wavy, curly, and color-treated hair each require a different keratin formula applied in the same session.
