I love Henna.
I've been putting henna in my hair for a little over a year and it is great!
Last night, with completely natural hair (I grew the process out instead of the BC), the henna worked like I always imagined that it would. My curls are looser.
I used Nour Pure Black Henna, which is really just indigo. I used to use the Hanna brand, but Nour is finer and works out a lot better. You have to be careful of products that advertise as black henna because it doesn't exist. Indigo is what you need if you want your hair to be black, but keep in mind, I've been reading that once you use indigo, you have to stick with it until it grows out. My hair is a dark brown with red highlights, so as soon as I see the highlights, I know it's time to henna my hair again lol.
Henna can be drying to the hair but I have a recipe that I use to mix my henna that isn't drying to my hair.
Also for the best results of jet black hair and you haven't hennaed before, do the red henna first, then the indigo. The hair comes out so beautifully black.
My recipe
1 full package of henna
Olive oil
Honey
Water
Lemon juice
I don't have any measurements for my ingredients as I do it by eye for consistency. The henna paste should be thick like a pudding. Indigo isn't the same texture as red henna, so the mixture isn't going to be as smooth, but that's how it's supposed to look.
I add the olive oil, honey and lemon juice first. I use the water to bring the mixture to the consistency that I want.
Then I let it sit in a warm place for 1/2-2 hours.
In clean hair (I co-wash), I just part and slather it in, cover it with plastic and let it sit my hair 1-2 hours.
As anyone can tell you, henna takes forever to rinse out, but you wanna make sure that you get it all out or it can dry the hair.
The olive oil and honey help to keep the henna from drying my hair, and it works great. The lemon helps to release the color.
Please make sure when using indigo, that it is indigo. Some suppliers of "black henna", the products have metallic salts or PPD in them. PPD can cause severe skin burns, sensitivity, and in severe cases, death.
I'd suggest for anyone looking for information on henna to visit
www.hennaforhair.com, this is a great website with a ton of information, member recipes, a link to mehandi.com to order great henna products.
If you don't have any Indian stores near you, henna is sold in just about all of the ethnic stores or health food stores. I got mine from a little African shop near my home. Islamic stores also sell really good henna, the best comes from Saudi Arabia, the red is phenomenal.
