The alteration of hair color using a natural agent, specifically a fermented apple product, represents a home-based cosmetic technique. This involves applying the acidic liquid to the hair strands, allowing it to sit for a period, and then rinsing. The goal is often to subtly lighten or enhance the existing hair tone, particularly for lighter shades.
This approach to hair coloring derives its appeal from the perceived gentleness and natural origin of the ingredient. Proponents suggest benefits such as reduced chemical exposure compared to synthetic dyes and potential improvements to hair health, including increased shine and a balanced scalp pH. Historically, natural substances have been employed for aesthetic modifications, predating commercially available chemical alternatives.
