Editorial In-Depth
Pure henna is produced exclusively from the dried, pulverized leaves of Lawsonia inermis, a flowering shrub native to North Africa, the Middle East, and South Asia. The active phytochemical coloring agent is lawsone (2-hydroxy-1,4-naphthoquinone). Lawsone is a small, lipophilic molecule that readily diffuses through the cuticular cell membrane complex into the hair cortex.
Once inside, lawsone binds to keratin via a Michael-type addition reaction, cross-linking with sulfur-containing cysteine amino acids. Because lawsone binds to internal proteins rather than sitting as a coating, it permanently thickens the hair shaft, seals cuticular scales, and creates an indestructible translucent shield that reflects brilliant auburn and copper light.
A critical distinction must be drawn between pure Body-Art Quality (BAQ) henna and commercial 'compound henna' boxed dyes. Because pure henna can only produce shades of orange, copper, and warm red, dishonest manufacturers create 'black henna', 'brown henna', or 'blonde henna' by adulterating cheap henna powder with toxic chemical additives.
The most dangerous adulterants are metallic salts—predominantly silver nitrate, copper sulfate, and lead acetate. When an unsuspecting salon client who previously used compound henna requests highlights, the hydrogen peroxide and ammonium persulfate in professional salon bleach react violently with the metallic salts. This exothermic reaction can cause hair to heat up to smoking temperatures, turn army green, dissolve into gummy mush, and break off at the scalp.
Before visiting a salon for any chemical service after using henna, communication is paramount. Never conceal past henna use from your colorist. A professional stylist will perform a mandatory mineral strand test: cutting a small clipping of hair and submerging it in a solution of 20-volume developer and 28% ammonia for 30 minutes.
If the hair sample turns green, boils, emits sulfur odors, or disintegrates, metallic salts are present, and oxidative bleach is strictly forbidden. If the hair sample merely lifts slightly without reaction, the henna was pure BAQ, and the colorist can proceed with customized corrective protocols.

Because lawsone forms a permanent chemical bond with keratin proteins, it is virtually impossible to bleach henna out completely to blonde. Bleaching will lift underlying natural melanin, leaving behind a permanent, bright neon fluorescent orange that cannot be lightened further.
So-called 'black henna' is frequently adulterated with massive concentrations of Para-phenylenediamine (PPD), a powerful synthetic dye allergen. PPD in high doses can cause severe allergic contact dermatitis, chemical burns, permanent facial scarring, and systemic kidney damage.
Use the authentic 2-step natural herbal process: first dye hair with 100% pure red henna (Lawsonia inermis) to deposit a red protein base. Immediately follow with a second application of 100% pure indigo powder (Indigofera tinctoria). The blue-green indigo over red henna creates an rich, permanent natural jet black.
