I have Hesh Amla that I purchased from a local Indain grocer on hand with another box packaged by another company. I paid $1.99 for each box. I haven't used it as like others, I did not find much on how to use the powder, but did find a YouTube video, but the natural sister only explained why she used amla and not how to use the powder. IIRC, the young woman's mother is East Indian.
I'll give the amla a whirl tomorrow afternoon, and post how my hair reacts. Oh, count me in the amla challenge.
I love the burgandy tint I get from henna, and hope amla won't darken my hair too much.
