This is perfect for beginners and experienced henna users alike. It mixes itself and gives you a mousse like texture for easy application and it doesn't drip! You simply add twice the amount of warm water as you use henna, so if you use 1 cup, put in 2 cups of warm water. Use a large bowl or gallon ziplock to mix--it really fizzes! Great fun, safe dye. You can perm, chemical color or bleach over this henna and you can use it over treated hair; as always though do a strand test to check your final color. There are no harmful metallic salts. Apply to dry hair. LINDA'S TIP: When I mix mine, I often add just a squirt of shampoo and conditioner, let it fizz then mix it with a mixer. This makes it foamy and easier to apply and wash out.
