Well, I don't know about patience! I'm just on a MISSION!
Plus I only keep it on 45 min. to 1 hour. I don't do it for color. My hair is color-treated jet-jet black.
I hope it works well for you. I'm loving my henna experience and have even transferred that henna love to my 12 yr old daughter, who now has a beautiful rich burgundy color after 3-5 applications to her "virgin" (no color) hair!
