This product only targeted pigment. so it won't work on light hair.
Hi, thanks for your question!
Treatments work best on darker hair types, or hair that contains more melanin. Melanin is the pigment that gives hair and skin its color, and will absorb light energy. Black and dark brown respond the best, although light brown hairs will also respond but typically require more treatments. Red may show some response. White, grey or blonde hairs usually don’t respond as well to treatments though some users have noted results after multiple treatments.
Hope that answers your question!
