ADDITIONAL INFO
Can you use this for dyed hair? Yes, you’ll just need to wait 5-6 weeks before you take your sample or at least 12 washings.
Does it have to be from the scalp? This is the preferred method. Armpit or pubic hair can be used. Please email me at carolyn@revitalance.com before purchasing to discuss more.
Will I have a bald spot from cutting my hair? No, we just need a small amount from several locations at the nape of your neck. It is about the equivalant of a teaspoon of hair.
