Review: Pain to apply, excellent results - I have black hair with gray all over it. This thing covered my grays for nearly 2 months. First time user, followed package instructions. The results show about a day after application. My hair was smooth and dark after application. The areas where the greys were, looked very, very dark violet in white fluorescent light although in sunlight looked black. And it's a pain to apply, leaving it on for about 90 minutes, it smells terrible but, it does the job and it's a thousand times better than the chemical, regular dyes (that also smell horrible). It's expensive. I have long hair down the middle of my back and had to use almost an entire jar but, hey, it's worth it. Results were great. Will continue to use and recommend this. I also recommend Googling other additional tips in order to cover the greys on black hair just in case. For example, I'd leave it more than 90 minutes next time.
Review: What the ingredients really are?! - A previous review mentioned the ingredients of this product are chemical. You really should get a dictionary and find out the meaning before your comment! The ingredients are the scientific name for Hanna, Indigofera and Lawsonia inermis are both natural plant-based ingredients commonly used in henna hair dyes. • Indigofera (typically Indigofera tinctoria) is a plant that produces a natural blue dye, often used in combination with henna to achieve darker shades like brown or black. • Lawsonia inermis is the scientific name for henna, a plant that naturally releases a red-orange dye. Both are 100% natural and plant-derived, not synthetic chemicals. However, some henna products may contain additives or synthetic dyes, so it’s always good to check for pure, high-quality sources.

## Features

- 100% ORGANIC
- NO CHEMICALS OR PRESERVATIVES ADDED
- TEXTURES HAIR AND GIVE IT BODY. Fades gradually. Lasts 4-6 weeks.
- HENNA IS AN ALTERNATIVE TO CHEMICAL HAIR COLORINGS that are controversial to health considerations.

## Questions & Answers

**Q: What are the ingredients? Does it have PPD? What chemicals does it have?**
A: They say 100% Henna. But they must add something more to get the different colors of the Henna. Otherwise it would be reddish in color.No PPD.

**Q: Can this product be used by itself or used after the original henna (orange color)? i was told to use this one (black from indigo) after henna.**
A: You can probably use this particular product after straight henna, or it can be used by itself too, i.e. no separate henna needed. 

 I've experimented with different combos, and like to mix dark brown henna with regular henna, and then indigo afterwards. This has given the deepest black so far so will most likely keep this routine.

**Q: Is this the original, counterfeit or old batch? it usually works so I was expecting very good reviews.**
A: The new Batch
It works great

**Q: Is this going to give me a black color or a dark brown shade? If I try multiple applications will the black shade take better to give an actual black?**
A: It darkens your hair if you use it the right way make sure to follow the instructions on the inside its helpfull to add lemon juice or another acid and let it sit out for a day or so before you put it on it's not quite black but a more  dark brown but it still looks nice

### ⭐ Does not work
*by C***A on November 18, 2018*

I used this three times and the last time I left it for 4 hours, even used dark coffee as part of the mixture as suggested. I have some grey near the roots. After the last attempt two weeks ago my and after washing my hair it was obvious Henna did not work. Finally decided to write a review. Much too late to return the product.
