Henna Dark Brown 4oz,17oz,34oz.

I have been using rainbow henna since my daughter was in kindergarten and she is now 36. I’m honestly not sure, but would probably be 90%grey by now. I have this down to a science. The secret is not to mix too thick and apply to clean dry hair. I have used both methods of a heat cap or if not I cover with shower cap then aluminum foil (for heat retention) and then a Terry wrap and go about my business for a few hours. It comes out great! Natural and no chemicals!! An inexpensive and safe way to keep coloring your hair!!

I have thick, long, medium/warm-brown hair and a lot of it that reaches mid-back. Last time I chemically dyed it all was about 10 months ago. Bought two 4-oz containers and used roughly 6 oz of henna mixed with coffee. Left it on my head for 3 hours (the first sections of hair were probably covered for about 5). It did leave it a bit darker, not as dark as I wanted it to be, but I think it might be darker with another use. The actual dyeing part was nuts - it became very crumbly (think coffee grounds) and there was bits of it EVERYWHERE. Probably tracked it around the house too because it would constantly fall off of me. I had to clean the bathroom like crazy afterwards and I think I’ll be finding henna in random places for the rest of my life now. However, this is just a consequence of using henna to dye my hair, so next time I’ll be more prepared to deal with the mess. Rated 3/5 stars because of the amount of time and effort that has to go into it to actually achieve significant results (which I guess is because I’m used to chemical dye so maybe it isn’t fair to compare them). But regarding this product from this brand, shipping was quick and it was packaged well. The included brochure was informative and appreciated.

Very nice product! Helped me finally switch to all-henna after using chemical products for decades! I mix dark brown and black henna ~70/30, and it gives me a nice natural-looking color. I have a lot of gray, and the coverage is nice, and gets better with every application. And I don't feel bad coloring my hair as often as I want, since it's not damaging.

Writing a review for both colors. I mix about 2/3 dark brown and 1/3 light brown, otherwise my hair is just too dark. I also use coffee as the mixing liquid. I love the color combination and how it makes my hair feel. Will continue to use as we all know henna is the best thing for coloring your hair. Thanks!

I've been using this for 10 years or so. My hair is healthier and prettier than any box dye could ever do. Excellent experience!

Nothing can bit Henna. The safest and easiest way to color the hairs. Henna makes hairs shinny, alive, and conditions the scalp so you will beautiful hair for the rest of your life.

This is an AWESOME PRODUCT. I ordered it for my mom. It arrived on her birthday. Right on time. She has has several terrible experiences with other hair colors: from dry and brittle to falling out. BUT RAINBOW got it RIGHT. Not only did it cover her greys well, her hair actually feels like Hair. And when she sweats, it’s not running down her back!! Thank You So Much!!!!

Aside from the prompt processing and mailing of the order, Rainbow Research produces a quality product. Mixing and applying the dark brown and burgundy to my roots gave me just the right smooth transition color to the previous hair color and highlights. More importantly the grey hair along my hairline and sporadically throughout my head are colored in the process (4-6 hours). Similarly to other henna users comments, I realized slight texturing and increased curl definition with the Rainbow Research henna. Both are welcomed outcomes. I recently purchased the heat conditioning bonnet sold by Rainbow. I'm hoping to significantly reduce the color processing time.

This product gives a pick-me-up to my hair and my psyche! Been using it for 20 years. Just love it. Smells like a salad on your head.

I have been using the Henna hair color for years and love it. It makes my hair very healthy and covers my gray great. I always get comments about how nice my hair is!!
