There are several styles of hair perm available on the market. Each of them utilizes a chemical solution known as ammonium thioglycolate. This chemical can be damaging to the hair and scalp. If the individual’s hair does not take well to the perm solution it may be damaged and take longer to grow back normally. The scalp may become irritated to varying degrees as well.
This type of hair perm is best suited to a square shaped face. It is designed to give your hair body, movement, and volume.
