- Sudden round bald patches: can centella cream help? There is no published human trial of Centella asiatica for alopecia areata or any other hair loss; the only hair-related studies are cell-culture work. Community users describe Centella creams as soothing for an irritated scalp, not as regrowth treatments, and a new bald patch needs a doctor's diagnosis first.
- Can PP405 help bald patches caused by stress? PP405 is an experimental topical gel from Pelage Pharmaceuticals that inhibits the mitochondrial pyruvate carrier; its registered Phase 2 trial (NCT06393452) tested it once daily in 78 adults with pattern hair loss, for safety and tolerability. It is not approved, not for sale, and has not been studied in alopecia areata or stress-related shedding.
- What do the latest studies say about bimatoprost for scalp hair growth? Bimatoprost is approved only for eyelashes; a single 30-person pilot reported better results than a topical steroid on patches of alopecia areata, but the two registered Allergan trials in male pattern hair loss were never published and never taken further, so scalp use stays off-label and experimental.
