Background: The efficacy of Finasteride 1mg, the first-line treatment for male Androgenetic Alopecia (AGA), tends to reach a plateau after several years’ treatment. Up to date, effective and safe options are limited because current modalities managing AGA have so far not taken into account the two key issues particularly relevant to excessive hair loss: the early onset of catagen (due to premature hair follicular cell apoptosis) and the frequently observed sustained micro-inflammation in the scalp.

Objective: We investigated the potential synergic effect of combining the oral finasteride 1mg, acting on conversion of testosterone to 5α-dihydrotestosterone, with CG210, a novel topical anti-hair loss product, acting on premature apoptosis and micro-inflammation in the scalp.

Methods: We designed a 12-month, randomized, double-blind, placebo-controlled trial using CG210 in twenty AGA volunteers already using Finasteride 1mg for at least three years. Hair diameters were assessed and compared for hair pattern improvement.

Results: The increase of hair diameter in the “Finasteride 1 mg + topical CG210” group was 37.7% more than that in “Finasteride 1 mg + topical placebo” group (p=0.002). No side effect was observed. Conclusion: In addition to 5α-reductase inhibitors, our study puts forward the approach to simultaneously address both premature cell apoptosis in the hair follicles and micro-inflammation in the scalp. The results suggest an efficient mode in the management of AGA with improved efficacy over the currently referenced modality. Furthermore, the studied topical CG210 may represent a new option for alopecia subjects, including those under finasteride 1mg, to improve their hair pattern.
