People affected by moderate hair loss turn to topical treatments like minoxidil (antihypertensive potassium channel opener) and finasteride (dihydrotestosterone-suppressing 5α-reductase inhibitor), the only Food and Drug Administration–approved treatments for inducing hair regrowth. Both are designed not for hair loss treatment but serendipity.
Researchers from North Carolina State University have identified a microRNA (miRNA) that could promote hair regeneration. This miRNA – miR-218-5p – plays an important role in regulating the pathway involved in follicle regeneration, and could be a candidate for future drug development.
Yeah, I know, miRNA (Micro RNA) differs from mRNA (Messenger RNA). However, I have become very cautious about anything that deals with my personal nucleic acids. So although I am beginning to notice that I am bald, and old, none of this for me. Yet.
