1. Why Hair Loss Happens
- Common Causes:
- Genetics: Male- and female-pattern hair loss caused by androgens or unclear hormonal factors in women.
- Other Factors: Thyroid issues, stress, trauma, autoimmune disease, and nutrient deficiencies.
2. Over-the-Counter (OTC) Products
Topical Minoxidil (Rogaine and Generic)
- How It Works: Stimulates hair follicles and extends the hair growth phase.
- Effectiveness:
- Women using it saw moderate regrowth in studies.
- Men using 5% minoxidil gained ~15 hairs per square centimeter, compared to ~8 hairs with 2%.
- Worth Trying? Yes. It’s widely supported by research.
Supplements (e.g., Biotin)
- Claim: Promotes hair growth.
- Effectiveness: Limited to cases of actual biotin deficiency, which is rare.
- Worth Trying? No. Evidence for most supplements is weak.
Low-Level Laser or Light Therapy
- Devices: Combs, caps, and headbands said to stimulate follicles.
- Effectiveness: Some evidence suggests it helps, but it’s not rigorously tested like medications.
- Worth Trying? Maybe. Results vary.
3. Prescription Options
Finasteride (Propecia, Proscar, Generic)
- How It Works: Blocks testosterone from converting to a hair-loss-related androgen.
- Effectiveness:
- Slows hair loss and stimulates regrowth, especially when started early.
- Won’t regrow hair lost for more than 3 years.
- Side Effects:
- Can cause libido issues, erectile dysfunction, and birth defects.
- Not for: Pregnant women or those not using contraception.
- Worth Trying? Maybe. Works well but with significant risks.
Spironolactone (Aldactone, Generic)
- How It Works: Blocks androgen receptors in hair follicles, reducing hair loss.
- Effectiveness:
- 74% of women in a survey reported stabilization or improvement.
- No large clinical trials yet.
- Side Effects:
- May raise potassium levels, affect blood pressure and kidneys, and cause birth defects.
- Monitoring Needed: Check potassium levels and discuss dietary changes with your doctor.
- Worth Trying? Maybe. Best for women with raised androgen levels.
Platelet-Rich Plasma (PRP) Injections
- How It Works: Plasma from your blood is reinjected into the scalp to stimulate follicles.
- Effectiveness:
- Small study showed a ~13-hair-per-square-centimeter increase after 6 months.
- More research needed.
- Worth Trying? Maybe. Promising but still experimental.
4. What to Skip
- Supplements marketed for hair growth unless you have a diagnosed deficiency.
- Relying on unproven treatments that lack robust clinical backing.
