Ingredients and how they work:

  • Henna (Lawsonia inermis): Henna acts as the perfect color agent in this mixture. This powder, which is derived from henna leaves, helps get the hair ready for the jet black color with its red hues. In addition, henna has natural conditioning properties which will leave your hair looking smooth and sleek!
  • Indigo (Indigofera tinctoria): For the actual jet black tone, we use indigo in the mixture alongside henna. The perfect ratio of this blue tone, along with henna, help us create a rich tone of black. Indigo powder helps add dimension and color variety when mixed with henna.

Tips and Notes: 

Helpful Tip: Please use fresh brewed black coffee liquid to mix henna for optimal results, you can use color safe, sufalte & paraben free shampoo after 48 hours of rinsing henna. It helps with getting the color stick to hair better and prevents color wash up.

Important Note: Henna hair dyes are different than conventional hair coloring products, it does not contain chemicals that are required to change the color of your dark hair, or develop color faster, with that being said, it takes around 2-3 hours minimum for the application process. Please reach out to us before placing an order if you have any questions about the application process.

Allergy Warning: 
Although, our Jet black henna hair dye is made with pure henna (50%) and indigo powder (50%) but some people may still be allergic to natural products, to rule that out for this product, please do a strand/skin test before full on application of Burgundy henna.


Jet Black FAQ:

Q: Why is this a two-step process? 

A: The two-step process gives better results than the one step (especially if you are a first time henna user or have lots of gray hair). Indigo needs a pure henna base to work off of in order to color properly, otherwise you’ll get strange colors like green (on light hair/grays), or blue/purple tones. 

Q: Can I do this in a one-step process? 

A: You can do this in a one-step process. To do this, you would still mix the two powders separately as they have different activation times (8-10 hours for the pure henna, 15 minutes for the indigo). Once each mixture has activated, mix the two together, then apply to your hair and let sit for 3 hours before rinsing.

Q: Will this cover my grays?

A: Yes, this will cover your grays. Be aware that grays are incredibly stubborn when it comes to being colored as they are texturally different than normal hair, and dryer as well. It may take a couple applications to get the grays to take to the color. 

Q: My grays are still red. What do I do? 

A: You can reapply the indigo powder to your grays, mixing the powder with black brewed coffee and a teaspoon of salt. This should help the grays accept the color and darken to the black shade you’re looking for.

Fully Satisfied

I’ve always wanted to have black hair, but knew that dying my hair with chemical dyes would be harmful to my hair. About 3 weeks ago, my friend suggested that I try the Jet Black henna by The Henna Guys, saying it was not only safe, but effective too. I tried it out and was astonished with the results. Now I have the dark black hair I’ve always wanted, and it looks great!

Loved It

I would recommend anyone to try out this Jet Black henna to get dark, beautiful hair. Along with coloring my hair, the henna also improved my hair health and eliminated dandruff. I'm so satisfied with it and have no plans to switch.

Complete Hair Care

No itching, no swelling, and no side effects. I found it to be the best natural way of covering grays. The kit comes complete with gloves, shower cap, application instructions and enough powder for multiple dying sessions.

Strong and Beautiful

The quantity is quite enough for shoulder length hair. For men, it's enough for head, beard, and mustache.My husband and I are both using the jet black henna for our hair and we have found it to be very nourishing for our hair. It conditions it and makes our hair beautiful and soft.

Wonderful Color

Every time I wash my hair, the color seems to be refreshed and visibly shinier. I used the jet black dye and it covered very nicely. Now my hair is smoother and the dye did not cause any itching on my scalp. I am ordering more today.
