Pure Persian henna mixed with Indian indigo for blue-black tints. It is an ancient Indian tradition to mix red henna with powder from the dried, fermented indigo root, to give dark hair deep blue glints. Indigo is not cheap, so there are some synthetic ‘black hennas’ around, but we want you to stay away from those! Lush Caca Noir is red henna with indigo powder, clove oil scent and Irish moss seaweed for softness. Cover it with Clingfilm and keep it damp for a redder colour, or let it air dry for a black/blue tint. Pick up any bits which fall on the floor or it’ll dye the rugs, too. – Lush Website
- Grate the block using a cheese grater. It is soft so it will grate easily. Grating it does take quite a lot of time and patience.
- After grating, add lukewarm water. Do not add hot water because heat breaks down indigo. Hot water can be added to other Cacas but not to Noir.
- Make a gooey paste as henna pastes are.
