Non-Surgical Options: What The Evidence Actually Supports

The non-surgical market runs from genuinely evidence-based medication through to shampoos making claims no shampoo can support. The dividing line is worth knowing before spending anything.

Finasteride is an oral 5-alpha-reductase inhibitor that lowers DHT, and it is the most established option for slowing pattern loss in men. It carries a recognised risk of sexual side effects in a minority of users, which makes it a conversation with a physician rather than a purchase.

Minoxidil works by a different mechanism, extending the growth phase rather than blocking DHT. It commonly causes an initial shedding phase and scalp irritation, and it is available topically or orally.

PRP uses platelets concentrated from your own blood to support follicles that are miniaturising but still active. It cannot repopulate a bald area, and its effects are not permanent — maintaining a benefit means maintaining a schedule.

What does not have comparable evidence: most cosmetic shampoos, the majority of supplements marketed for hair growth in people who are not actually deficient, and devices making regrowth claims without published trials. Some of these are harmless and some are expensive. Very few are doing what the packaging implies.

The honest framing for all of it: non-surgical treatment defends hair you still have. It does not restore hair that is gone. Anyone with an established bald area who is being sold a topical as an alternative to surgery is being sold the wrong product.

Which does not make these treatments unimportant — the opposite. A transplant without a medical plan for the surrounding native hair is a result that deteriorates. The two halves work together.
