They’ve been looking into the mysteries of Wnt signalling – the protein pathways that pass information from cell to cell – and have concluded that a breakdown in all that information-relaying could well be a key to hair loss. Now all they need to do is work out how to correct that…

Platelet-rich plasma performs well with androgenetic alopecia

According to a recent study in Spain, patients who received a half-head treatment of platelet-rich plasma to treat androgenetic alopecia showed a clinical benefit at 6-month follow-up. 25 patients were given the platelet-rich plasma treatment on one side of the scalp, and placebo on the other half-head, over the course of six months – with a significant improvement detected on the treated side.
