Thinning Hair

Finding more hair in the drain than usual is genuinely scary, and the internet doesn't help. Here's the honest version: there's one OTC ingredient approved to regrow hair, a lot of products that make hair look and feel fuller, and a few situations where you...

The short answer

Minoxidil is the only over-the-counter ingredient FDA approved to regrow hair, and we don't sell it, so ask a pharmacist or dermatologist. The serums, oils and shampoos here support a healthy-feeling scalp and fuller-looking hair. Sudden or patchy shedding deserves a doctor's visit to check causes like iron, thyroid or stress.

Thinning Hair, answered.

What actually works for thinning hair in women?
Topical minoxidil is the only OTC ingredient FDA approved to regrow hair, including a 5% foam approved for women. Dermatologists have other options too. Scalp serums and volumizing care can help hair look fuller but aren't approved to regrow hair.
Does rosemary oil regrow hair?
Evidence is limited. It's a pleasant scalp ritual and won't hurt most people, but it's not a substitute for proven treatment if you're losing hair.
Does biotin help hair growth?
Only if you're actually deficient, which is uncommon. Heads up: the FDA has warned that biotin supplements can interfere with some lab tests, including a heart test. Tell your doctor if you take it, and check your multivitamin label.
Is postpartum shedding normal?
Increased shedding a few months after giving birth is common and usually temporary. If it isn't easing after several months, or you see patches, check in with a doctor.
When should I see a dermatologist?
Sudden shedding, bald patches, scalp pain or itching, or a widening part over months. Hair loss often has a medical cause worth finding.
