Hi Prettylady,
Thanku very much for yr advice. I'm going to color my hair black... I just want to know whether I can use,henna permanent dye? And I also want to know will it stay black till my hair grows out??

Thanks

Henna dye can last just as long as permanent hair color until the hair grows out. However, these dyes require allergy tests because it can cause moderate or severe skin reactions, although it's rare. If you haven't used henna before, be sure to do a patch before applying the dye to your hair. The patch test involves putting a dab of hair dye behind the ear or inside the elbow, leaving it there for two days, and looking for itching, burning, redness, or other reactions.
