What is a hair-pull test?

πŸ’‘ Quick answer

A clump in the brush is not a pull-test number. Photograph; let an exam happen.

A positive pull can support active telogen. It does not grade Norwood. Traction and technique matter. This page will not invent a PMID. Related: anagen-catagen-telogen β€” different URL.

Do not start oral finasteride from a self-tug video. Do not double minoxidil after you hurt the part.

Pain, pus, or hair coming out with skin is dermatology now. This is not medical advice.

More foam if pull is positive?
