Review: Amazing Natural Hair-Matching Henna Product for Roots and Healthy Scalp - This brand and color is exactly the same as my natural color, it's amazing! No hard dye lines. I only have a little bit of white hair, so the other chemical salon color roots products were overkill, bland, and severely damaging to my hair and scalp. Inversely, Henna is wonderful because it works with your real hair color, adding color and diversity to your strands, based on their own natural color, giving an overall natural healthy shiny look. As the hair grows out, there is no noticeable hard line, and it blends so nicely. This henna looks very natural and lasts way longer than chemicals for doing roots. With this, I can go 4-5 weeks without coloring and look fine. With chemicals, I had to redo roots every 2 weeks because the dramatic hard line looked awful. Henna fades a bit, which is good for the natural look. With henna powders, I add a few things. I use 1 spoon of instant coffee mixed in with the hot water and henna powder. I add cinnamon for smell and a spoon of fresh squeezed lime juice for potency and action. I let this brand mix sit for one hour sealed, then put it on my roots for one hour, then I leave it in my hair for 3-4 hours. Rinse out, no shampoo, using a tiny bit of conditioner at the ends to detangle and comb. Do not wash or rinse for two days and sleep with a black towel on your pillow. (A bit itchy and dusty, but worth the longer last!) Then resume shampoo and conditioner about twice a week. Henna hair products can be a bit dirty and crumbly, so there can be extra clean up needs during the process and for those first few days. This two pack lasts me 4-5 months; I do a half jar for roots once a month.
Review: GREAT product! I'll never go back to chemical colors. - I've been coloring my hair for years. After going platinum for over a year, my hair was destroyed and I decided to take a break from chemicals. I grew it out for awhile and eventually got most of the fried bleached bits off. I was just going to let it grow for awhile with no color, but had more grey than I would like. (though less than I was expecting lol!) so I decided to give the henna a go. I did a lot of research on different brands since I had never used henna before and decided to go with Rainbow in medium brown. My hair is thick and coarse and I used about half of one tub the first time I tried it. The powder had a light smell, kind of like tea. There are directions on the tub that I basically followed. I added coffee and a little apple cider vinegar. I covered it and let it sit in a bowl for a couple of hours. When I applied it, it smelled HORRIBLE! (though honestly, better than most chemical colors) I applied it to damp hair, covered my head with plastic wrap and left it on for about an hour and a half. I rinsed in the shower which I would recommend because it takes a lot of rinsing. My shower was a mess afterwards, but cleaned up easily. The smell lingered in my hair for a few days, (the dry powder "tea" smell, not wet poo smell). I got so many compliments on my color from my friends. Not mentioning until after what I had used. They just kept telling me how shiny and rich my color was, and I agree. I didn't color again until about 3 months later. The color wasn't as vivid as it was initially, but still looked acceptable. When I mentioned to my mother I was coloring my hair, she proclaimed that I probably didn't even need to, but with it being summer and swimming a lot over the past couple of months it definitely did. This time I applied it to dry hair, and noticed it did not go as far as when my hair was wet. I would absolutely recommend applying to damp hair. Overall I LOVE this product and will continue to use it in the future. Especially for how long it lasts and how far one tub goes.

## Questions & Answers

**Q: Should you try this if you have short hair and balding ?**
A: It may depend why you are balding--your bare scalp could be extra sensitive. I used it on my hair that was about 3/4" long, growing back after chemotherapy with no ill-effect. I often use a tablespoon of melted coconut oil in the preparation which helps condition dry hair and skin.

**Q: why is my scalp so itchy and after leaving the henna for six hours did not change my original brown and gray hair?**
A: six hours is very long. you have to heat up your head. I use a dryer with the plastic cap. and cook for 1/2 hour then keep in for 1/2 hour and it covers my gray. I also use coffee rather then water. You have to heat it up that's a must.

**Q: Can this be used for tattoos?**
A: Yes, but they would turn out better if you got body art quality straight henna. If you do end up getting this product use lemon juice or another acidic juice, not boiling water. Also make  sure to let the henna sit 2 hours or more for the dye to release.

**Q: How long does it take the henna to release dye ?**
A: because I use it to cover my grey hair, I use strong coffee and a spoon of apple cider. Mix it into a muddy mixture and apply. I cover with a plastic cap and sit under the dryer for 45 minutes. that's it, and works great.

### ⭐⭐⭐⭐⭐ BEST natural hair color!!
*by B***M on November 24, 2017*

As a 35 + year cosmetologist retired I can say this is the best hair color that I have used. It's no chemical. I was afraid it wouldn't last or hold color so I left it on for 3 hours. I'm mixed half of the jar of powder of the medium brown two tablespoons of olive oil because my hair is dry and coffee hot to consistency of a Jello that is half done. I did miss some powder in the bottom and added more hot coffee later to get the ends of my hair. That's all I put on it covered with a shower cap and then with a turbie Twist towel, tightly wrapped, 3 hours rinsed for 15 minutes lukewarm water not hot , used Wen shampoo, not irritating, and if you have a horse shampoo don't use it, just use water until your water is clear. Then I blow dried to set the color in and here it is. I love it. It will be deeper the second time. I don't believe I will ever use anything else since I'm a vegan all natural. It smells like dehydrated spinach but that smell will go away. You've come a long way baby! Henna is now great. and one picture before and 2 after pictures. I had dark roots coming in. I had not colored my hair for at least a year or more. and I'm standing right by a light so in darker areas it does look darker. I will wait 6 weeks and do it again. Really easy if you have a baster and have your mixture thick enough to stay on your hair not to be runny. Don't mix it in a runny consistency. Keep it thick with a wiggly Jello consistency, not runny. Basted it on the ends but get all the roots first put the ends on top and go around the sides and back and top with your baster. over the ears As well. Spinach washes right out so you can use your baster for other things. Make sure you soak your baster and wash with Dawn dishwashing liquid. If your mixture is thick enough you will not have a mess and your hair will look beautiful. Really healthy. I also got some argan oil to add on top for more shine. Not here yet.
