Scientists believe they have cracked the code to restore hair to its original color. They have found a protein called wnt that is responsible for producing color in hair and also stimulates hair growth and produces new hair follicles. The lack of wnt activation in melanocyte stem cells leads to de-pigmented or grey hair. So far experiments have been performed on mice but it may be just a matter of time before hair products that raise wnt levels in humans appear on the market. This will be good news for those who are tired of frequent root touchups.
