Yes, our dyes are permanent. Once applied, rinsed, and matured(48 hrs), that will be your hair color until it grows out, or is cut off. *Please Note: initial uptake of the natural colors may take two to three applications. And color will fade from the hair under certain stress, similar to traditional chemical hair dyes. For example: chlorine bleach, extreme sun exposure, regular shampooing(retail brand shampoo), intense heat(blow-drying) all slowly strip the pigment from the hair. The hair itself actually gets damaged under these conditions: natural sheen oils burn off, proteins weaken or are destroyed, and the henna pigments are exposed and release early and/or fade.
The more you color with henna-based dyes, the deeper and stronger the colors will fuse…and harder to strip-out. A good secret to keep color is a non-sulfate, all natural shampoo (one with natural surfactants like coconut oil or olive oil)—cleans away the funk, but leaves the natural pH balance, preserving natural protective sheen oil content and vital nutrients.
