Safe for all hair types including chemically treated and relaxed hair. Leaves hair shiny, soft and beautiful. Directions: Apply a generous amount of Bigen Semi-Permanent Hair Color directly from the bottle to shampooed, towel-dried hair. For best results, use entire bottle to ensure hair is saturated.

For longer-lasting results, place plastic cap over hair and process under a warm dryer for 10 minutes, then allow to cool for 5 minutes. Heat is not recommended for freshly relaxed hair.
