In short
The average person has 5 million hairs, which grow all over the body except on the lips, palms, and soles of the feet. Healthy hair takes about a month to grow half an inch, and most hairs grow for up to six years before falling out to be replaced by new hairs. Hair helps keep the body warm and protects the eyes, ears, and nose from small particles in the air. Common problems with the hair and scalp include hair loss, infections, and flaking.

About this page. This page brings together public information from official sources, each cited where it is used. It is not medical advice, it is not a diagnosis, and it does not tell you which treatment to take.
Treatments. Indications are quoted unchanged from official product information (European Medicines Agency, U.S. Food and Drug Administration). They describe what a medicine is approved for, not whether it is right for you. Approved uses can differ between countries. Always read the package leaflet and follow your doctor's or pharmacist's advice.
What people report. Figures marked "reported by Anpheros users" are anonymous counts from at least 20 people who agreed to share them. They show what people report, not what works, and they are not clinical evidence.
Links between terms. "May be associated with" means the link appears in a cited source. It does not mean you have that condition.
In an emergency, call 112 (or your local emergency number). Do not delay seeking medical help because of something you read here.
