why is henna used in hair
Henna hair dyes coat the cuticle, or outer part of the hair shaft, and do not penetrate the cortex of the hair, where the hairâs proteins and moisture are housed. This means that henna provides shine and condition to the hair, and the cocoa butter is deeply hydrating. Henna hair dyes are a great alternative to synthetic hair dyes because they do not alter the structure or texture of the hair, and have added benefits to the scalp as well.
