I personally use herbs and berries to dye my hair. but I have used this website to change it temporarily. has alot to do with your ability to concentrate. found at http://magic-spells-and-potions.com/askSFX/spell_to_change_hair_color_eye_color_more.htm I've used this persons spell and its worked.
thank you wasted energy
saftey always comes first kids
but yes consider the dangeres as well
and mabey yu should just get some dye i mean its faster then a spell. anf if yu want it permanent then go for permenent dye and wen it grows out dye it again.
it doesn't cost much.
Its true there are spells out there that can alter ones appearance but it can be a long process and it's not worth it when its just the hair you want to change i would just have to say Hair dye. If there is any other part of the body you wish to change there are some spell i know of ex: Physical appearance, teeth, weight and so on.
Hope this helps....
