I took the Red shade and got excellent vibrant copper color on my originally dark blond. I used chamomile tea as liquid according to the recipe. I have middle-back-long hair and about 85% of the container was more than enough. All the roots and grey hair are perfectly covered. The final color is awesome! There is no noticeable scent.

My Favourite Henna

This is the best henna I've come across so far. The powder is very finely milled so it mixes easily to a very smooth and creamy paste without lumps. It has a very mild, slightly earthy natural scent that reminds me somewhat of dried hay, and when applied to the hair, the paste produces a rich, vibrant colour that increases in saturation the longer you leave it on. This red shade compliments my fair European complexion and blue eye colour perfectly, no matter the season (right now it's summer so my skin is lightly tanned). A little goes a long way for me so it's also economical. (I get about 4-5 applications per container.) My hair is smooth, glossy, and fine (but there's lots of it), and its length is five to six inches past my shoulders. (With denser, coarser hair you may need to use more paste.) This is an ideal product for those who prioritise their well-being and want a natural method to enhance the appearance and maintain the health of their hair. Highly recommended.

I’m never going back to box dye!

I can’t believe I never tried this before. This stuff is amazing. I love that it’s all natural and it covers greys better than the boxed stuff without effecting the texture of my curly hair. You have to leave it on for about 2 hours but it’s so worth it. It does have an earthy scent that lingers but I only notice it when my hair is wet and it fades over time.

Good quality

This came well packaged. It’s a good size and seems to be of good quality. I will use it soon. It has a neutral scent. I would recommend this brand. I like that it is natural. It is good for your hair as it conditions it. It has a good composition.

Rainbow Research – Henna Hair Colour & Conditioner (Red)

The colour payoff is strong and natural, and it conditions the hair more than chemical dyes. It takes some patience to mix and apply, and the earthy smell is unavoidable with henna, but the results last well and leave the hair feeling thicker. A solid option if you want plant-based colour.

Awesome

Very nice henna, was easy to use and the color is fantastic. My hair smelled funky for a week like some spice or herbal market but I guess that's normal for henna

This is the only stuff I'll use!

It's super fine milled and excellent quality making it much easier to use and rinse. I have super long hair to the back of my thighs and 2 jars is plenty because they're of good size to do a touch up once a month. The color is brilliant and colors my gray hair to blend in with the rest of my reds. I wouldn't change brands. Always love the natural earthy smell. iherb had the best price I can find and it's on a subscription. It doesn't get better than this!

Second time purchase

I’ve used this product before and really liked the results, so I decided to buy it again. The color lasts a long time, and the powder has a perfect consistency. It’s simple to use — I mix it with liquid and a bit of acid, let it sit for several hours, then apply it to my hair and rinse with warm water after about four hours.
