About HairBase
HairBase is an independent, evidence-based hair-loss information hub published by all-lifes.com and available in nine languages. We are not doctors and this site is not medical advice. Our goal is to make trustworthy, evidence-graded information about hair loss, treatments and hair transplants accessible to everyone.
Every medical statement is drawn from reputable primary sources β peer-reviewed reviews, StatPearls/NIH, the American Academy of Dermatology, the NHS and ISHRS β and linked so you can verify it yourself. Our self-assessment tools give an estimate to discuss with a clinician, not a diagnosis. Always consult a qualified dermatologist before starting, stopping or changing any treatment.
