Regrowth Index

Independent, evidence-based reference for hair loss. We read the trial data, dermatology guidelines, and primary sources, then explain what the research actually says about causes, conditions, diagnosis, and treatments.

Every claim is cited to a primary source. No paid placements, no affiliate links, no clinic bookings.

Coverage spans pattern hair loss (AGA), telogen effluvium, alopecia areata, postpartum hair loss, scarring alopecias, and the major treatments: minoxidil, finasteride, dutasteride, JAK inhibitors, hair transplants, microneedling, PRP. Plus the diagnostic side: blood panels worth requesting, when to see a dermatologist, how to read a hair loss study with proper skepticism.
