Hair loss · What is approved, what is promising, what is marketing
Minoxidil, finasteride, PRP, mesotherapy and the peptide claims.
Medically reviewed by Bernard Garcia, MD
What it is
For pattern hair loss, two treatments are FDA-approved: topical minoxidil and oral finasteride (men). Oral minoxidil (off-label), PRP, scalp mesotherapy, microneedling, low-level laser and peptide serums (including GHK-Cu) are marketed with evidence ranging from moderate to none.
How it works
Minoxidil prolongs the hair growth phase; finasteride reduces DHT. Both need continued use. PRP has small positive studies with unstandardised preparations. Mesotherapy "cocktails" vary by clinic and lack controlled evidence.
Research status
| Research area | Status |
|---|---|
| Topical minoxidil | FDA-approved |
| Oral finasteride (men) | FDA-approved · sexual side effects documented |
| PRP scalp injections | Small studies · unstandardised |
| Peptide serums / mesotherapy | Weak or no controlled evidence |
Status reflects published research context only and is not a statement of safety, efficacy, or suitability for any person.
Is it legal?
Minoxidil (topical) and finasteride are FDA-approved. Oral minoxidil, PRP, mesotherapy and peptide serums are off-label or unregulated. This is a general note, not medical advice.
Frequently asked questions
Do peptides regrow hair?
No peptide has evidence comparable to minoxidil or finasteride. GHK-Cu has cosmetic-grade data at best.
Is finasteride safe?
It is approved with documented side effects that a provider will discuss; it is not for women of childbearing potential.
Does Vitrex provide any of this?
No. Hair treatments are discussed with a provider after an intake.
