Hi guys,
I'm really considering henna because although I do like my virgin color, I have very thin and weak hair. I wouldn't mind a bit of a shade change either though. However, reading around I noticed that henna may change my hair texture to be less wavy. I'm worried about that, since I feel that the small amount of wave I get is what makes my hair look thicker than it actually is and gives me more volume. On the contrary, many people seem to notice thicker looking hair after henna. Really, my main goal is to have thicker looking, less flat hair.

So for those with fine or thin hair,
how has henna affected your thickness and volume? Has henna helped your thin hair or weighed it down? Also, for those with either thick or thin hair, if henna took away your wave, did your hair appear more flat after treatments?
