How damaging are semi permanent hair dyes?
Semi-Permanent hair dye has varying degrees of damage, since there are many different kinds and brands. For some hair types it can be extremely harsh on the hair and the scalp (if the hair dye is applied incorrectly and gets on the scalp) and for others it barely does any damage. It also depends on how damaged your hair is originally, if you had your hair relaxed or permed (or another harsh chemical treatment), and how you plan to maintain your hair after you dye it. If you have had your hair permed or something similar then you should wait at least a week or two to dye your hair. If you don’t you could end up losing all your hair (since the chemical processors weaken you hair). Overall Semi-Permanents aren’t too bad for your hair as long as you condition after every rinse or shampoo. If you are still worried, you should try CLAIROL semi-permanent hair dyes. They are good, cheap, and don’t damage the hair much. GOOD LUCK!
