Does it wash out/fade(will I have to deal with roots, basically)? What are the best brands to try? is there a way to strand test it or do you have to do your whole head?
Ive been using henna for 10years now, and i m soo happyy with it i never chemically dye my hair! No henna doesnt wash out, u will have to wait till ur hair grows back... ive always used the one u can get at the nearest indian/middle eastern store, make sure though its pure henna not mixed with something else..
u will have to touch up the roots every 2 months but u dont need to the whole head.. i basically bend down in the shower, massage my scalp with my henna mix and leave it for 4h, wash it et voila!
u can do a strand test before u try on ur whole head. my mix is:
300g of henna ( from indian store)
2-3tablespoon paprika (to help for that red glow)
4 bags raspberry tea
2tbsp of honey (good conditioner)
1tbsp of olive oil (conditioning)
let it sit for ~10-12h in warm place for dye release, put it on make sure all ur hair is well covered (i have long hair i always use 300g, be careful its messy and the stains are hard to get rid of!) i keep it for 4h (the longer the richer and the deeper the color will be) i hop in the shower and wash with lots of conditioner.
I get a deep rich chestnut hair (my har is naturally dark brown), it really work great for me!!
