The proven drugs target the hair cycle and the hormone that disrupts it, but the environment in which follicles live also matters. A scalp affected by chronic inflammation or seborrheic dermatitis is a less hospitable place for follicles, and treating these conditions with antifungal or anti-inflammatory shampoos can reduce shedding and improve results.
In-clinic procedures: PRP
Platelet-rich plasma therapy involves drawing a small amount of the patient’s blood, concentrating the platelets rich in growth factors, and injecting that concentrate into the scalp. The evidence is genuinely mixed: several studies report improvements in hair density, while others show little effect. PRP is best understood as an adjunct to proven drugs rather than a replacement for them.
Light, needles, and the role of adjuncts
Low-level laser therapy uses specific wavelengths of light to stimulate follicles; the evidence is modest but not absent, and it appears safe, making it a reasonable low-risk add-on. Microneedling has shown the most promise when combined with minoxidil rather than used alone, with several studies suggesting the combination outperforms minoxidil by itself.
Evidence Check: PRP and laser therapy have moderate/mixed evidence. None replace the proven foundational drugs.
Hair transplantation: moving resistance, not creating it
Surgical hair transplantation is the most durable option for established loss. Because the follicles at the back and sides of the head are genetically resistant to DHT, surgeons can move them to thinning zones, where they keep their resistance and continue growing. Modern techniques extract and place individual follicular units for natural-looking results. Important caveats: transplantation redistributes a finite supply of donor hair rather than creating new follicles, and the original pattern loss continues in untreated native hair unless managed medically.
The horizon and how to judge it
Hair science is an active field, with early-stage work on follicle regeneration and cell-based therapies. A useful filter for any new option: ask what the human evidence actually shows, how it compares to the established drugs, and who stands to profit from the claim. Be wary of clinics that promise dramatic regrowth from advanced baldness.
Spending money wisely on hair
Spend in proportion to evidence: the proven drugs first, then well-supported adjuncts, and only then the experimental options — with clear eyes about their uncertain returns. Treating the proven core as the priority and everything else as optional extras keeps both expectations and budgets realistic.
