TLDR Finasteride works better for baldness in people with shorter gene repeats.
This study analyzed the effectiveness of finasteride on male pattern baldness (MPB) patients with different androgen receptor (AR) gene polymorphism. The study found that the smaller the repeat number of the triplet repeats (CAG+ GGC) in the AR gene, the higher the improvement with finasteride. Patients with shorter repeat regions in the AR gene responded better to the drug than those with longer repeat regions, although the former patients tended to reveal severe initial symptoms. The determination of such polymorphism is thought to be useful in the drug choice for MPB patients.
