Then the next question will be: Are you accept this trade off - having to repair and maintain your hair regularly (so that it will eliminate the dry/damaged hair look) in exchange for having permed hair? Do note that having permed hair reduces your styling/blow-drying time, flexibility to have a variety of hairstyles and real good volume in the hair.
If yes, you have many options to look at. Vitamin booster, hair conditioner or even hair mask. And just in case you're worrying about the hair turning straight after using these products, rest assured that they will not. Because the hair bonds are already structurally damaged through chemical means.
My hairdresser did suggest to me to go for a light perm as my hair is really really straight. Guess your points are valid and I shall consider it!
