Frequently asked questions
Does PRP regrow hair?
Evidence is limited. Some small studies suggest modest improvement in thickness for pattern hair loss, but results vary and it is not a guaranteed or standard treatment. Proven medical options should be considered first.
Can treating iron or thyroid help my hair?
Yes, if those are the cause. Low iron and thyroid problems can cause hair thinning, and correcting them can help — which is why a check-up is worthwhile before pursuing costly treatments.
