Henna (also called hina or mehndi) comes from the leaves of the shrub Lawsonia inermis. It has been used as a dye for centuries across South Asia, the Middle East and North Africa. The dried leaves are ground to a powder and mixed with water into a paste. In the U.S., henna is an approved color additive for hair only, not for skin.[1] Here’s how henna works on hair and what to watch for, plus a certified-organic pure henna.Disclaimer: This article is general information, not medical advice. Patch-test new skin and hair products, and see a dermatologist for persistent skin problems.
Henna safety
Uses and Benefits of Henna
Pure henna gives red-orange to auburn tones, and on gray hair it can turn bright copper. Mixed or layered with indigo, it gives browns and blacks. Henna can carry the USDA Organic seal because it’s a farmed plant.[3] But “organic” doesn’t mean hypoallergenic, and the FDA doesn’t define “natural” for cosmetics.[4][5] Cosmetics can’t legally claim to treat skin or scalp conditions.[6]Using Henna as a Hair Dye
- Plant dye – Pure henna has no ammonia, peroxide or PPD. It coats and stains the hair’s outer layer instead of opening the cuticle. It can’t lighten hair.
- Hair growth – There’s no good evidence that henna makes hair grow. The coating can make strands feel thicker.
- Feel – Many people find hair feels smoother and shinier after henna. Others find it drying, and adding a conditioner afterward helps. It doesn’t repair split ends.
- Scalp reactions are possible, so do a skin test 48 hours before every use.[2]
Henna Dye Essentials and Procedures
- Time Consuming – Pure Henna Dye takes a long time to color the hair. It may take anywhere from 3-6 hours. It also needs to be mixed a good while beforehand for it to develop properly.
- Long-lasting – Henna doesn’t really wash out. It fades a little at first, then stays until it grows out, so it’s hard to undo. Indigo fades faster.
- Stains the skin – Henna stains skin and nails, so wear gloves and put oil along your hairline.
- Compound henna – Some “henna” products contain metallic salts or synthetic dyes. Read the ingredient list (it should list only Lawsonia inermis), and before a later perm, bleach or salon dye, tell your stylist and ask for a strand test.
- Never black henna – Pure henna is never black. “Black henna” may contain PPD and can cause severe reactions.[1]
What the Research Says
The FDA approves henna as a color additive for hair only, and warns that products sold as “black henna” may contain PPD, a common cause of allergic reactions.[1] Dermatologists recommend patch testing before any hair dye.[2] The FDA doesn’t define “organic” or “natural” for cosmetics; a product can carry the USDA Organic seal only if its agricultural ingredients meet USDA standards.[3][4] Plant ingredients can still cause allergic reactions, and fragrance is a common cause of skin irritation.[7] Cosmetics can’t legally claim to treat or cure skin conditions; products that do are regulated as drugs.[6]How We Chose These Products
We don’t test products hands-on. We compared labels and listings: ingredients and fragrance, what any organic claim covers (USDA seal or third-party certification) [8], skin type, and price per ounce. We removed three products: two henna powders whose listings make no organic claim, and a “henna cream” whose color comes mainly from synthetic HC dyes. On October 18, 2026 we checked the remaining brand against CPSC [9] recalls and openFDA enforcement records[10] and found none. Brands don’t pay to be included, though we may earn a commission from purchases.Our Picks: Organic Henna for Hair
