Is black henna safe? How to spot natural henna

Baskets of herbs and pottery in a Marrakech souk
In shortNo. "Black henna" is not a type of henna: it usually contains PPD (para-phenylenediamine), a hair-dye chemical that can cause blisters, scarring and a permanent allergy. Natural henna is a green powder that stains skin orange, then reddish-brown, never black. If a design turns black within minutes, say no.

What is natural henna?

Natural henna is made from the dried, ground leaves of Lawsonia inermis. In Morocco it is part of weddings, Eid and the bride's henna night. The powder is green and smells like hay; mixed into a paste, it is left on the skin for several hours.

Why is black henna dangerous?

PPD is meant for hair dye, not for direct skin contact. On skin it can trigger severe reactions days after application, and sensitise you for life, so later hair dyes and some fabrics can cause reactions too.

How to stay safe in Marrakech

  • Ask to see the paste: it should be green to brown, not black.
  • Avoid street stalls offering "fast, black" designs.
  • Patch-test natural henna 48 hours before if you have allergies.
  • Keep henna away from eyes; external use only.

At Oumi Rituals we only use natural henna, ground and mixed in front of you.
