Not the kind of bleach for your clothes but hair dye? And should you bleach it when dying it or no?
It depends on what bleach and how healthy/dark your hair is. If your dying it a dark color then no need for bleach but if its a brighter color than your hair i suggest bleaching with a bleach that a salon recommends or in my case my brother recommended. Your hair should only fall out if you bleach it like 100 times in a month. It does make your hair feel stiff for a week tho. My brother has bleached his hair or dyed it a diff color each week since i can remember and his hair tho its not so soft or natural hes deffnitly not bald. Just be careful how much you use what company it is and how long you bleach it and how much you bleach your hair. I hope i helped.
Bleaching your hair should be a last resort. Its very strong chemicals and can cause lot of damage if its not done properly. A better alternative if you need to lighten up your hair before dying it is to get the color stripped out of your hair. Its still chemicals...but they are less harsh and damaging then bleaching. Its not always neccasary to bleach or strip your hair before dying unless your hair is black, very dark brown, or your dying your hair a bold color.
If your hair is coloured dark, you'd be better off getting an effasor as opposed to bleaching it. An effasor is like a colour lifter, it removed colour and is less damaging than bleach.
bleaching your hair, wipes out your natural colour or any other colour you have in your hair, and if your thinking about bleaching it then dying it no
i wouldn't even bother bleaching your hair, i've done it. it ruins it so bad! trust me! :/
