Hair loss is the top aesthetic concern men search for, and one of the most under-discussed for women, who make up a large share of thinning-hair patients. The good news: the era of “nothing works” is over. The catch: what works depends heavily on why you’re losing hair and how early you act.
Why you’re losing hair
The overwhelming majority of hair loss is androgenetic: pattern hair loss driven by genetics and hormone sensitivity, appearing as a receding hairline or crown thinning in men and diffuse top-of-scalp thinning in women. Follicles don’t die overnight. They miniaturize over years, producing progressively finer hairs until they stop producing at all.
That timeline is the single most important fact in this topic: treatments reactivate weak follicles far better than they resurrect dead ones. Every year of waiting shrinks what’s recoverable.
Not all hair loss is pattern loss, though. Sudden shedding, patchy loss, or a scalp that itches, burns, or scales points to medical causes (thyroid issues, autoimmune conditions, nutrient deficiencies) that need a physician’s diagnosis, not a spa package.
What actually works
PRP (platelet-rich plasma) is the med spa treatment with real evidence behind it. Your own blood is drawn, spun to concentrate the platelets, and injected into thinning zones, where growth factors push miniaturizing follicles back toward productive growth. Studies consistently show increased density for pattern loss, strongest in early-stage thinning, over an initial series of three to four monthly sessions, then maintenance once or twice a year.
Prescription therapy (finasteride for men, minoxidil for either, among others) remains the foundation most results are built on. It slows the underlying process while PRP pushes regrowth. The strongest published outcomes generally come from combining the two. Any med spa that talks you out of the prescription conversation is optimizing for their revenue, not your hairline.
The supporting cast of red light devices, peptide serums, and nutrition ranges from “modestly evidenced” to “mostly marketing.” Nutrient deficiencies genuinely cause shedding, but that’s a blood test and a supplement, not a monthly drip subscription.
How to choose a provider
Ask three questions: Do they assess what kind of hair loss you have before quoting a package? Do they photograph and measure at baseline so results are provable? And do they bring up prescription options alongside PRP? Yes to all three is the profile of a provider treating patients rather than selling sessions.
