Excellent for my Chemotherapy-Treated Mother's Greys!!!!!!!!!

Posted by iHerb Customer on July 17 2011 | Verified Purchase

It was really hard to convince my Mom to go with a henna product for her grey hair, which turned from a dark, chocolate brown, from chemotherapy, for breast cancer. I have been using the Rainbow Research henna, Persian Red for about 3 months, and it's been doing a really good job of making my greys look like red streaks, which I don't mind at all. I've tried other brands in past, and it was at-first very, very difficult to convince my Mom that this wouldn't make her hair red/orange. She had been using a commercial semi-permanent color, and I was really afraid for her to keep using it. My Mom was adamant about not wanting to do anything more to her hair, I had asked her many times about our having a "spa day" with henna for her greys, and she was too tired or non-believing to accept the offer. When I was ordering some other products at Iherb.com I ordered this as well and had the box sent to my mother's house. She was then able to look at the innocuous jar, and decided she would try it. She was very, very nervous throughout the whole process, but I knew I wouldn't get her to cooperate if I had purchased a 2-step process for grey hair. My persistence and like of my own experiences with this brand of henna paid off, big time! I followed the directions for use with grey hair, vinegar and coffee, no water, for mixing. I don't make a fuss with my own henna concoctions, and just use an ordinary old towel, let it "bake" for about an hour, and I'm always happy with my Persian Red. Well, her hair came out so so close to her natural chocolate brown. I knew the fibers would also help fill in a bald spot on the top of her head. That's why I gently pushed her toward this product as it's a very simple, fast mix, application (I just basically glop it on myself and my Mom with plastic gloves, newspaper on the floor and old towels). And then like my wn process, we just wrapped her hair in an old towel for an hour. Ok, it's a bit messy, but honestly, the results were just gorgeous!!!!! We only rinsed it out with water and then conditioner, and this is an important piece, do not wash it for 24-48 hours. The dye sets in during this time, and the conditioner you use during your rinse will make it very soft. I am really happy and impressed with this henna brand. It's affordable, reliable, and just fantastic! BTW: her grey was about 20-30%. And the bald spot looks a little more filled in. It was also really fun to give my Mom something that she at first refused, but which allowed us to bond, and which had really, really great results. Her hair had lovely dark brown highlights instead of the greys, blended so naturally, my Dad even complimented! AS+++++++++

My hair looks and feels wonderful

I had read the reviews and thought it was 'worth a try'. Previously I tried a Lush Cosmetics Henna block (Caca Bruin), but it required 4 hours in the hair, which was not feasible. This is much easier. For this I followed the directions for hair with grey (that is to use brewed coffee and 2 tablespoons of apple cider vinegar), I bought a hairdresser's cape, wear old clothes and apply Vaseline to my face, neck and ears! I apply the mix with with my hands in disposable gloves and work from the front to back, scalp out to ends, twisting it in strands and patting it onto my head. I achieve good covereage, but if the mixture is a bit thick, it doesn't get right down to the roots. I have found I need to add much more coffee/vinegar than the one cup specified (maybe two cups?) to get it to the slurry stage - more 'gloopy' but not runny. Then I wrap my hair in cling wrap, put on a shower cap - and if others are around, put a towel over the top, turban style. Rinse out using a hand held shower (easier) then condition. My hair looks beautiful at the end, so the two hours (including showers to wash hair before and after)is time well spent. I don't mind the henna smell,so the fact it is there for a few days doesn't bother me. No one has commented about it (other than my husband) so perhaps it isn't obvious anyway. The colour does fade a little, but no obvious lines because it fades to my dark brown hair colour. I tend to get a bit of regrowth (the grey hairs) after about 3 weeks so will probably do it on a four week cycle. After a few goes, you become quite fast at doing it. I leave it on as long as I can (usually about 1.5 hours) and can potter around home. So persevere - it isn' difficult!! The results are much nicer than chemical dyes and my hair is much softer.

i have a lot of white hairs among my deep brown hairs though i'm only 28 years old! whenever i've got under some big stress they spread all over my head. so i tried this stuff without that much expectation the result of right after rinse it out was not that great. light red color laid on my entire hairs and the white ones turned into mahogany red color. but after three or four more washing, they were not any more that visible. then i applied it on my hair once more, now i don't feel have white hairs any more. they are now light brown, gradated in my own hair. needless say that my hair is healthier than before. 새치가 너무 많아서 한번 시도해 봤는데요. 처음 염색 하고 머리를 감았는데 새치가 불그스름해졌더라구요;; 근데 머리를 몇번 감으니 애들이 뭔가 왠지 잘 안보이게 되길래 염색을 한번 더 했어요. 그러니까 뭔가 그라데이션 된 것 처럼 새치가 감춰졌어요 ㅎ 머리도 전반적으로 불그스름한 갈색으로 코팅됐구용 ㅋ 인디고로 염색을 한번 더 해야 완전히 가려진다는데, 전 이게 더 나은 것 같아요 ㅋ 그리고 머릿결에 정말 좋아요 ㅎㅎ 단점은.. 한번 염색할 때 기본이 세시간이라는거;;;;

Rainbow Research Henna

Posted by iHerb Customer on April 5 2016 | Verified Purchase

I have been using this henna for about 7 years. I mix it with very strong coffee and put in 1/2 cup of beet root powder to get the "cherry coke" color. It is very conditioning and completely safe and healthy to use. There are tips on the Rainbow Research website on things you can add for different effects. Another thing I add is 2 tsp of Bragg's Apple Cider Vinegar. It helps with covering grey. A little Argan or olive oils also helps with conditioning.

Did not work for me

Posted by iHerb Customer on April 8 2010 | Verified Purchase

I have dark hair with a few gray. I have tried it twice following the instruction. It is messy and the gray coverage is about 10% for me. It still looks gray. I am disappointed. It does give my hair a good shine. But that is not the purpose I purchased this product. Will not buy it again.

Best Henna I have tried

Posted by iHerb Customer on September 6 2009 | Verified Purchase

I loved this henna because it lasts more than 25 days. I have tried other brands that last only 15 to 20 days. It also gives tons of volume-body and great tones to my hair.

Thanks for your feedback!

Tremendous product, especially for those who cannot use peroxide and ammonia in their hair. Be sure to follow their instructions. My hair feels great weeks after using the product. Also very happy with speedy delivery and price.

I've been using this henna for a few years now and still love it. I had tried many different types of henna before, but never liked any of them vey much. They all seemed to gradually turn a reddish color on my hair. Not so with this henna. Maybe there is some slight fading of the color, as some people have reported, but nothing that would be noticeable to anyone but yourself. I always use coffee and apple cider vinegar, and leave it in for 2 hours when I can. Wash out without shampoo but use conditioner to get all the grit out. Let it set a second day or two before washing again using shampoo- altho I once forgot and it was still just fine. I find that the color stays in my hair and I really only have to recolor the new growth. Great stuff.

Thanks for your feedback!
