My hair is thinning in my twenties. What actually works to stop it?

Hair loss in your twenties is frustrating, but there are proven options:

Clinically proven treatments:

• Minoxidil (Rogaine or Hims/Keeps generic) - topical or oral, stimulates hair follicles. The most accessible starting point. Keeps and Hims offer convenient subscriptions with doctor consultations.

• Finasteride (Propecia) - prescription pill that blocks DHT, the hormone driving most male pattern baldness. Very effective but requires a doctor. Hims, Keeps, or Roman can prescribe it online affordably.

• Combining both works better than either alone.

Worth adding:

• Nizoral shampoo - ketoconazole formula has some evidence for reducing scalp DHT. Use a few times a week.
• Nutrafol - supplements with some clinical backing, though weaker evidence than the above

Honest reality checks:

• Start early - these treatments preserve hair better than they regrow it
• Results take 4-6 months minimum
• Finasteride has potential side effects worth discussing with a doctor
• Avoid expensive laser helmets and most "natural" remedies - weak evidence

My honest recommendation: See a dermatologist or start with Keeps or Hims for an online consultation. Getting on minoxidil and finasteride early is genuinely your best bet.
