A hair relaxer uses similar chemicals to a perm (which gives you waves or curls), only it straightens your hair. A relaxer will damage your hair, much like a perm. So if your hair is already damaged, be careful and go to a good salon.What are hair relaxers?
nooooooooo really ok for black peole that menas to straghten our hair whcih is bad they do break the hair off,ok perm like perm u'll get curly
If your hair is damaged from the dying it and bleaching it I would advise you to wait a while until your hair can get back healthy... A relaxer is a chemical used to straighten tight curled hair... If you have damaged hair I would suggest that you make sure to go to a professional salon to get your hair back healthy. I hope everything works out... in the mean time may i suggest using a CHI flat iron to get your hair straightwithout chemicals.
A hair relaxer is just that, it relaxes the curl in the hair. African-Americans use them to the greatest extent to relax their very kinky hair. If you don't like your curly hair, the relaxer may not get rid of enough of the curl to suit you. You may need to have your hair straightened. Go see your stylist and ask her what you can do to straighten or at least relax your hair. This is not something you do at home, a stylist needs to do it.
