Reduction of telogen rate and increase of hair density in androgenetic alopecia by a cosmetic product: Results of a randomized, prospective, vehicle-controlled double-blind study in men.
Considerable parts of the global population are affected by androgenetic alopecia (Androgenetic Alopecia).
The efficacy of a foam containing nicotinic acid hexyl ester, polyphenols, zinc, glycine, and caffeine in comparison with a vehicle control foam was assessed in a double-blind vehicle-controlled study in men with Androgenetic Alopecia over 6 months.
Sixty-two men with Androgenetic Alopecia were assigned either to the active ingredients (verum) or the vehicle group. They applied the products twice daily on affected scalp areas over 6 months. Automated phototrichograms were obtained at baseline, after 3 and 6 months. In addition, a clinical rating by a dermatologist and by the subjects themselves was documented using standardized questionnaires.
The reduction of the telogen rate from T0 to T6 was significantly stronger in the verum group compared to the vehicle group. The reduction was significant from T0 to T3 and T6 in the verum group, but in the vehicle group only from T0 to T3, not to T6. Significantly increased hair density was noticed in both groups at all time points, but the change from T0 to T6 did not differ significantly between the groups. Cosmetic acceptance of the foam and its application regimen was generally good in both groups. Slight reddening and burning after application of verum in six cases was probably due to the presence of hexyl nicotinate.
The study demonstrated a reduction of the telogen rate by a cosmetic foam in men affected by Androgenetic Alopecia, indicating a benefit for cosmetic intervention against male pattern hair loss.

I know, the argument is who else beside the manufacturer would provide a study on this foam. Still, let's keep that in mind when reading the results.
Reviews from real customers tend to provide negative feedback for Androgenetic Alopecia treatment.
