The anti-aging hair routine that really works!

Want a head of hair like you had in your twenties? Researchers say you really can regrow thinning hair . . . here’s how!

1 Stop shedding with peptides! Applied to the scalp, natural peptides “anchor” hair in follicles, keeping strands in place, Biomed Research International reports. Try: Peptide Complex Serum by Eva Naturals, $14.20, Amazon.com.

2 Thicken with supplements! Taking a daily combination of 460 mg. of black currant seed oil, 60 mg. of fish oil, 5 mg. of vitamin E and 30 mg. of vitamin C thickens hair and decreases hair loss for up to 90% of women, reports the Journal of Cosmetic Dermatology. “Black currant seed’s and fish oil’s omega fatty acids ease inflammation and help nerve endings heal,” explains New York City hair restoration specialist Robert Dorin, D.O. And vitamins C and E prevent hair-loss-triggering free radical damage. Important: Always get your doctor’s okay before taking any new supplements.

3 Hydrate with coconut oil! Got hair that’s brittle, coarse and/or breaks easily? Readily absorbed coconut oil infuses hair with hydration that stops breakage and smooths frayed cuticles, plus its antifungal and antibacterial properties help KO dandruff and other hair-limiting scalp woes. Just rub a small amount between palms, then run hands though hair from roots to ends, a section at a time, reapplying oil as needed. Or massage the oil into your scalp weekly; let sit 30 minutes, then shampoo. Try: OGX Coconut Miracle Oil Penetrating Oil, $6, Walmart.com.

4 Spur growth with caffeine! Applied to the scalp, caffeine blocks the hair-loss-promoting hormone DHT, reports the International Journal of Dermatology. “Caffeine also stimulates the hair shaft, further encouraging growth,” says Dr. Dorin.
