Frequently asked
Common questions.
Will shampoo regrow hair?
No. Only minoxidil (or finasteride for men) has clinical evidence for regrowth. Shampoo prevents further loss.
How long until I see results?
Reduced shedding at 4-8 weeks. Visual density at 12-16 weeks. Most users abandon at week 6.
Should I see a dermatologist?
Yes, especially for sudden thinning. Address underlying causes (iron, thyroid, hormones) first.
