We use not only the PRP, but also biologics-- Wharton's jelly. Wharton's jelly is a substance derived from the human umbilical cord. It is rich in mesenchymal cells (MSCs), which are important for cell growth and hair follicle development. The use of stem cells, which Wharton's jelly contains, has shown to improve hair regrowth and regeneration of hair follicles.
