Androgenetic alopecia is the most common type of hair loss in men and women. The Wnt/b-catenin pathway has been implicated in hair follicle development and hair regeneration in adults. Wnt/b-catenin activators like Valproic Acid promote human hair cell proliferation. CXXC5 is a negative regulator of the Wnt/b-catenin pathway which was upregulated in human balding scalps. However, scientists have found a way to black this negative feedback using PTD-DBM. This peptide, PTD-DBM, is often used as a part of larger hair protocols in conjunction with other peptides such as GHK-Cu, Zn-Thymulin, and Thymosin Beta with tremendous results.
