Hair Loss Shampoos & Serums: Honest Answer
The short answer: somewhat, depending on the product and cause of your hair loss.
What Actually Works
Minoxidil-based products have the strongest evidence:
- Rogaine (2% or 5% minoxidil) is FDA-approved and clinically proven to slow loss and regrow some hair
- Keeps and Hims offer minoxidil-based topical treatments with good results
- Works best for hereditary hair loss (androgenetic alopecia)
Ketoconazole shampoos show real promise:
- Nizoral reduces DHT on the scalp, which contributes to hair loss
- Studies show it can be comparable to minoxidil in some cases
More Limited Evidence
- Nioxin shampoos improve scalp health and hair appearance but won't dramatically regrow hair
- Biotin-infused products (like those from Viviscal) help mainly if you have a deficiency
Honest Caveats
- Results take 3-6 months minimum
- They work better at preventing further loss than regrowing hair
- They stop working if you quit using them
- They don't address all causes (stress, thyroid issues, etc.)
Best bet: See a dermatologist to identify your specific cause before spending money on products.
