any tips for dying my hair?

Dying your hair black definitely ISN'T temporary, even if you use a semi-permanent dye. Black doesn't come out at all without bleaching. Unless you have shorter hair and you grow it out completely, I wouldn't recommend doing it unless you're super committed!!

If you do end up doing it, I recommend using dye that comes in an aluminum tube that you mix with lightener (idk where you're from but I use the brands Crema Colour and Colour Royale) and it works super well and looks way better than traditional box dyes if you're doing it yourself!! good luck :)) <3

put vaseline on your forhead so it doesnt stain
