A centre-part photo is not a diagnosis. Photograph the same lighting; do not shop JAK ads from a Sinclair number.
Ludwig I–III is a classic female-pattern sketch. Sinclair adds more steps some researchers use. They are maps, not millilitres. Male Norwood is another file. This page will not invent a PMID. Related: female-pattern-versus-te — different URL.
Do not start oral finasteride from a Ludwig screenshot. Female and pregnancy rules differ. Do not double minoxidil because a scale jumped on a humid day.
Sudden patches or a child with loss skip scale shopping. This is not medical advice.
