Shampoos that Kill a Perm

Q: I just got a perm yesterday, and my stylist did tell me to avoid some shampoos brands that contain some kind of chemical that will kill the perm. I forgot what the name was of this chemical. I can't call her, she went on vacation, please help me.

A: Ok, as for specific chemicals in shampoos that will "kill" a perm, I know of none. I've often had to explain to clients and readers that when properly performed, permed hair should be as stable as the hair before the perm.

The concerns over washing the hair too soon after a perm are a matter of making absolutely sure that the curls are neutralized and fully stable.

There is also the matter of permed hair being left more porous than virgin hair, which can be exacerbated by using a more alkaline shampoo, which can strip moisture from the hair and can cause damage to porous hair types.

So, if I had to make a recommendation, it would be to simply use gentle shampoos and conditioners and pay attention to your hair and how it feels at any given time. Use a leave-in conditioner to keep it feeling soft and moisturized and to protect it from styling damage and the heat of your dryer.
