Bio Organic 100% Pure Indigo Powder Color for Natural Hair Dyeing | Organic Indigo Powder Without Preservatives & Dyes | Protects Hair From Damage -Plant-based Hair Dye 3.5 oz

I had two new gray hair out of no where, so decided to look for an all natural way to cover and prevent. I mixed this w/ half part henna and black tea. I let it sit overnight (as I read this releases the henna and color). And then let the mixture sit on my hair overnight. I don't know if it needs that long, but I had the time so decided to do that. Rinsed the next morning to black soft hair and the two grays gone. I tried other brands of indigo henna and my hair my still left a dark ashy brown and it didn't cover those two grays. I've already ordered a few more boxes of this brand to keep on hand as I plan to use it every 6 wks or so for preventative. This will definitely be a staple for me!

Doesn't cover Grey well and does last more than 2 days

This product didn’t work for my hair. Instead of a dark brown my hair turned a burgundy color.

Wow- this seriously works! I mixed a TINY amount (MUCH less than a pinch) in with oil that I use on my grey hair and it took out the yellow immediately and has lasted months so far!

There was no color

During and after rinsing, there was lots of debris stuck throughout my hair which made it very challenging and time-consuming to wash out! Very gross & gritty product! Very disappointing! Had to throw the rest in the trash. See pics. The pics don't tell the whole story... These pics are towards the end of rinsing. It was waaaay worse than what you see in the photos. ...I just decided to take a picture at the end when I got fed up & thought I should warn others. If you like having debris-filled hair, this is the product for you!
