Hair Color — SL

Full-head hair color using premium ammonia-based dye — ideal for a fresh new shade, seasonal color change, or full grey coverage. Your stylist mixes the formula in-house after a short consultation to match your desired tone and skin undertone, then applies and processes it for even, saturated color from root to tip. The SL size is for waist-length hair or hair that's been chemically treated before (which needs extra processing to take color evenly), running close to 2.5 hours total.
