Contra-indications when bleaching

Postby chris the limey » 22 Oct 2010 03:51 pm

Do not proceed with the bleaching process in the following cases:
1 When the hair has been coated with a metallic substance, e.g. hair colour restorers.
2 If hair is overprocessed or excessively damaged, e.g. after over-perming.
3 If the hair is extremely fine or fragile -use a very mild bleach only and test hair carefully beforehand.
4 When any contagious or infectious diseases are present on the hair or scalp.
5 When there are any severe cuts or abrasions on the scalp.
