    TLDR A complex of 5-aminolevulinic acid and glycyl-histidyl-lysine peptide may help increase hair count in male pattern hair loss without side effects.
    In a 2016 study, 45 male patients with male pattern hair loss were treated with a complex of 5-aminolevulinic acid (5-ALA) and glycyl-histidyl-lysine (GHK) peptide (ALAVAX) to assess its efficacy and safety. The patients were divided into three groups: group A received ALAVAX 100 mg/ml, group B received ALAVAX 50 mg/ml, and group C received a placebo, all applied once daily for 6 months. Group B showed a significant increase in hair count with an average of 71.5 hairs, which was statistically significant compared to group C's 9.6 hairs. Group A also experienced an increase of 52.6 hairs. Satisfaction was highest in group A at 26.7%. No significant differences were found in hair length and thickness among the groups, and no adverse events were reported. The study concluded that the 5-ALA and GHK peptide complex could be a complementary treatment for male pattern hair loss.

      The user has been on finasteride and minoxidil since 2020 and increased dutasteride and minoxidil doses in June 2024, but still experiences hair loss. Despite trying pyrilutamide without success, opinions vary on whether the hair loss is significant, with some suggesting it might be due to lighting, angles, or a regular shedding cycle.
