Do you notice your hair is drier since it is gray? Gray hair tends to be dryer than pigmented hair because the loss of melanin also means loss of sebum or oil to keep hair moisturized. If you are gray AND natural you have more reason for dryness with your gray hair because kinkier hair has a harder time for the sebum from the scalp to reach the whole shaft of the hair. All the more reason to try to do a pre-poo treatment to help keep your gray hair moisturized.
