1, principle and composition: chemical substances such as ammonium sulfate or sodium sulfate are used for healthy perm, and the hair structure is changed by opening the hair scales to better maintain the curly state. Swarovski perms, on the other hand, use newer ion perming technology, and use lower concentration of sulfate or ammonium sulfate to treat hair in a gentler way.
2, effect and durability: a healthy perm can produce more obvious bending and curling effects, and the durability is relatively long. Swarovski perm, on the other hand, tends to have a natural and relaxed wave effect, which may last a little shorter.
3, damage to the hair: because the ingredients and treatment methods used in Swarovski perm are relatively mild, in contrast, the damage to the hair will be less. No matter what kind of perm technology, it will cause some damage to the hair, so the care and maintenance after perm is very important.
