How to Use: Henna

Henna, Lawsonia inermis,is a natural hair colorant that produces a red-orange dye molecule, lawsone. Henna contains hennotannic acid which, when mixed with hot water, will coat the hair. It seals in oils and tightens the hair cuticle giving your hair a rich, healthy shine. Henna has no lightening action, so the shade that you choose will depend on your hair color (natural or tinted) and it must be noted that Henna will not work as a colorant if your hair has more than 10% gray. Its effects will last up to 3 months. 1

Preparation Methods & Dosage :Powdered henna leaves form a base for body art and natural hair dyes. Follow product instructions for hair coloring.

Henna Side Effects: Some premixed pastes have been found to include: silver nitrate, carmine, pyrogallol, disperse orange dye, and chromium. These have been found to cause allergic reactions, chronic inflammatory reactions, or late-onset allergic reactions to hairdressing products and textile dyes. Buy only organically grown, pure henna from reputable sources. Avoid "Black" Henna boosted with PPD (para-phenylenediamine), it can cause lifelong health damage.
