How does Bigen Powder compare with semi-permanent colors? Bigen Powder and semi-permanent colors are crucially different with regard to lasting color. Bigen Powder lasts about 4 to 6 weeks, while semi-permanent colors last about 2 to 3 weeks, washing out gradually. All permanent hair colors, including Bigen Powder, require a preliminary skin allergy test before each use. Your body constitution and condition change every day.
Contact duration. As semi-permanent dyes are a stain, how long a semi-permanent dye lasts is affected by contact duration. A dye that is left on your hair for longer will often stain the hair more effectively and will take longer to wash out. A shorter contact duration leads to a colour that won't last as long.
