    TLDR CGF from platelets helps hair regrowth in people with androgenetic alopecia.
    The study demonstrated that concentrated growth factor (CGF) from autologous platelets significantly promoted hair regrowth and improved hair density and appearance in 15 patients with androgenetic alopecia (AGA) over 12 weeks. Hair density increased from 40.8 ± 17.4/cm² to 50.0 ± 20.9/cm², and the terminal to vellus hair ratio improved from 47.1% ± 17.3% to 80.2% ± 43.6%. Most patients reported satisfaction with the treatment, and no adverse effects were observed, although some experienced slight pain during injections. The study concluded that CGF treatments were effective and safe for promoting hair growth in AGA patients, but noted the need for further research with larger sample sizes and long-term follow-up.
