Jet Black Henna from The Henna Guys:

🌿 Conditions and adds shine

🌿 Means no more irritation, bruises, or burns

🌿 Covers grays and colors your hair naturally

🌿 Boosts manageability and promotes hair growth

🌿 Improves overall hair health with continuous use

Ingredients and How They Work 

🌿 Henna (Lawsonia inermis): Pure henna, milled into powder form before undergoing a triple-sifting process, forms the red-orange base of our henna hair dyes. We create different shades by blending henna with other natural ingredients.

🌿 Indigo (Indigofera tinctoria): When applied alone, pure indigo powder imparts a green- or blue-tinged tone to darker hair and is colorless on white and gray hair. When mixed with henna powder, indigo creates various shades of auburn, brown or black. However, red undertones usually appear in all colors but black.

* It’s very important that first-time users use our jet-black henna as a two-step process for the best results.

Allergy Warning: Although our henna hair dye is made with natural ingredients, sensitivities and allergic reactions to even natural products are possible. If you do not know your allergies, Always start by doing a strand/skin test before applying any henna.

Disclaimer: Individual results may vary. These are 100% natural products, and benefits are not guaranteed. Outcome may be affected by other factors like the type of shampoo or conditioner being used, as well as any other chemical hair treatments in the present or past that may affect results.

    Excellent product quality, fas t shipping! Great Company!

    Beautiful, I used the henna and the indigo powder in 2 step process with the option of using coffee instead of water. My hair looks really black. AWESOME. I let the henna and the indigo powder more time than the suggested on the instructions and it worked great.

    It was legit. This time around we knew exactly what to do and how much to make and it made the process a lot easier. Definitely will continue to use Henna then store bought hair dye.

    Incredible product

    I am very happy with this product. I am very allergic to hair dye and it’s great to find a product that conditions my hair and covers the gray. It leaves my hair soft and shiny! Love it!

    Grey to black

    Instructions were helpful and although my hair did not turn all go black, I will try it again in 4 weeks. I do have areas of a orange tone but rest of the grey turned brown and black hair darker. Did give my hair a nice shine!

    Nice product and quality

    Of course henna is such a messy process but this is a wonderful product and creates such nice, shiny, healthy results. As someone who went from blond to black, the red was still quite pronounced and my hair was not black afterward but I did a second process for 4 hours of Indigo. That made it much more black but I can still see red. I like it very much and know it will just take some more time until it is fully black. I really wish there was an eyebrow product through your company that dyed the skin as well.

    Great Henna and Indigo

    This was my first purchase from the henna guys. The shipping process went great and I got my order in about 2 days. The package came with gloves, a plastic cap, 100 grams of henna, and 100 grams of Indigo. I used 1/2 pack of both the henna and indigo for my shoulder length 4b natural hair. The henna was easy to mix and it was ready to use in about 8 hours after mixing. I added aloe vera powder to my henna mixture as it can be quite drying for my hair type. The henna was easy to apply and rinse out. The Indigo was easy to mix and rinse out as well. My final color was not black, but appeared to be more of a dark copper color. I used the henna to cover my grey hair and this was my first application of henna in a while, so that could be the reason my hair did not come out black. I will try again using coffee to mix the henna to get a darker color. Overall the product was ok and I would use it again.

    Process too long to get results

    I do not have the patience to use this product. I spent an entire Saturday using the 2-step process and the roots of my hair were red, not black. I understand that if I use the process again, my roots will probably get darker, but I don’t want to spend that amount of time just to color my hair.

    The application process was not bad and the results turned out great. I choose this product because it was not chemically based and did not alter the texture of my natural hair. I most definitely will be using this product again

    The Henna and indigo

    I love black hair but I begin to have extreme allergic reactions as I got older it got worse so I haven't been able to dye my hair black for about 6 or 7 years. I tried Henna in the past but never could get my hair black until now. Your Henna and Indigo two step processed worked! I have amazing results and I have dreadlocks so my locs are black for the first time since I locked my hair. Finally something that works with no reactions. Thank you all so much! ❤

    Good Product For My Hair

    Jet black henna not effective in grey hair

    Henna was well sifted, unlike cheaper brands, indigo smelled cleaner than other brands I’ve used. The indigo didn’t grab my henna stained hair at all though, it was like I had not even applied it. I left the henna on overnight and applied the indigo immediately, leaving it on for 4 hours. There was no difference in color with the indigo. My hair was stained reddish orange, however, so the henna appeared to be very potent. Overall, not the look I was going for. Now my grey hair is reddish orange amongst the rest of my black hair. I’m disappointed.

    Rich Color

    Love it! My hair is naturally darkest brown, but after bleached strands and multiple colors on top of it, I wanted a dark, rich color and I got it! I have dreadlocks and they look much healthier and feel softer now.

    Perfect for cancer survivors

    I absolutely love this product. It covers grays and conditions my hair without harsh chemicals. After swimming in the ocean, my hair remained soft and manageable. My color is still a deep jet black as well. The only downside is the time that it takes to allow the henna and the indigo powder to activate. But, I’m here to tell you, it’s worth every minute.

    This covered my gray

    Amazing product. I left the henna on for 3.5 hours and the indigo on for 4. Full gray coverage. I am so thrilled to find a non toxic way to color my hair:)
