Is it possible to fix a widow's peak without needing surgery?

I suggest seeing a hair loss expert now to evaluate and go over your condition and provide you information about your best treatment options. There are great non-invasive options like prp/progesterone and/or hair transplantation. See an expert. Best, Dr. Emer

No, not usually. The hairline changes that lead to a widow's peak represent a form of maturation of the hairline. The only way to change is surgery for most people.
