How can I bleach my hair at home?

Can I bleach my hair with leave in conditioner in it?

No. You can if you want but it’s not necessary. If your shampoo protects your hair or even if it doesn’t, it will put a coating on the hair strands making it harder for bleach to loosen the cuticle which is necessary to change the melanin in order to bleach and color the hair.

ON A NOTE:  How can I grow my chin hair at 15?
