Rainbow Research Henna Hair Color and Conditioner Persian Dark Brown Sable - 4 oz

I've been using this for years, but now my hair is much grayer as it grows out, the color isn't the same. WARNING>>>Henna sites will tell you to use indigo with henna for gray coverage and yes it does work. But if you try to grow it out, you will end up with a blue line of demarcation from the gray into the henna and it may take two years or more to grow out. So use this product alone, not with indigo. Lesson learned. And professional colorists may or may not be able to help with the transition. Good product if used alone - you just need to remember it's permanent, it layers inside the hair shaft, so make sure you are ready for the commitment.

I use this henna to enrich my hair follicles to make them thicker and healthier. Also, it did add colour to my dark brown hair making it darker as well. This is a great product. Definitely a 10 and a 10 I will be ordering more and next time I will get the black instead of the dark brown.

Here's what will happen if you have a small amount of gray hair or more, and use this product… It will turn your hair dark reddish orange. I don't know about the other colors that Henna offers and how they perform, but the dark brown version should not be used at all, unless you're dressing up for Halloween and going as Bozo the clown, because that's what it will do to your hair… Sad to say it turned my graying temples and gray in front all dark reddish orangey brown. The only reason I bought this product was because it's all natural and chemical free, and I'm all about organics and purity when it comes to my health, but ironically I had to go and run out and try and cover up this horrible dye job with the chemically laden hair dye " Just for Men"...that's that wonderful product that comes with all kinds of warnings because of possibly all of the radioactive plutonium and isotopes it must contain.. and after re-doing the crappy Henna job with just for men...my hair still looked like carrot top...as well as my head felt like the monster from the alien movie just regurgitated on top of my head and his acid was melting my scalp...my freakin head was on fire...they really should rename that product to something like "Just for Dead Men", so they look good in the coffin… because that stuff is intolerable on any living creature. Well needless to say my hair is ruined for at least a month because oh Henna… and so I am rectifying the situation by shaving my head tomorrow… Luckily I'm a Buddhist so it's not a big deal, and I'll just let it grow back In (I'm Buddhist but I'm still not ego-less....yet lol)...and in the future I think I'll just let myself grey naturally. Again to reiterate I'm only commenting on the dark brown product because that's the one I've used… I don't know about their other products, but if this is any indication of what they could be like… You might want to just run from this company and never look back... and you probably want to run from "just for men" too, unless you don't mind glowing in the dark and having your head burst into flames like "Ghost Rider".

I’ve been using this for almost a year now to cover greys and make my natural red/brown highlights stand out and I’m so satisfied. I wanted to note a few things. -You must mix with enough acid to cover greys. Coffee or tea isn’t going to work if you’re trying to cover grey. You MUST use a substantial amount of apple cider vinegar, otherwise the chemical reaction that makes the henna turn dark isn’t going to happen. -henna oxidizes after a couple of days. This means, the color you see when you first rinse it out is not the color it’s going to be. I always wait a couple of days after coloring to see how dark it gets. It will get darker. If it’s not as dark as I’d like, or my greys aren’t fully covered, I do a second pass over the areas I want darker. -henna is messy, and takes time. Just deal with it. I do it all in the shower with gloves to contain the mess. Yes, it does leave a residue in hair, but that always washes out after my second wash. -be sure to use conditioner afterwards to prevent dryness. Also, steer clear of any products with protein for a bit. Henna acts as a protein in your hair, and if you put more protein in after using henna, your hair will suffer protein overload which could result in dullness, extreme dryness, and breakage. All in all, henna is not for everyone. I’m willing to take the time, energy, and mess over putting harmful chemicals in my hair. And after a year of using this product, my hair has grown significantly, is incredibly strong, and absolutely beautiful.
