TLDR Sildenafil, often used for erectile dysfunction, may help hair growth.
In 2018, a study found that sildenafil, commonly known for treating erectile dysfunction, has a significant effect on promoting hair growth, suggesting its potential as a treatment for alopecia. The study showed that sildenafil increased the proliferation of human dermal papilla cells (hDPCs) and up-regulated the mRNA expression of growth factors such as VEGF and PDGF, which are crucial for hair development. Additionally, sildenafil enhanced the activation of the ERK pathway, which is involved in cell growth, and improved perifollicular vessel formation in mice, leading to the transition from the resting phase (telogen) to the growth phase (anagen) of the hair cycle. The study did not specify the number of participants or samples used.
