Really appreciate her sharing her story. You would think she was just lucky to be successful. You never know how discipline she is and how much difficulties she went through to become this successful. She is an inspiration to me.

The box came completely destroyed. On a difficulty scale from 1-10 of how difficult it is to prepare and apply this henna is about 5/10. The results only lasted 2 weeks. Will not buy again. UPDATE: Within 3 weeks the henna came out of my hair. I only wash my hair once a week. Barely changed the color of my hair. Still...won't buy again.
