A "hair pull test"is a medical procedure used to assesshair loss. It involves gently pulling on a small bunch of hairs to determine how easily they detach from the scalp.
The hair pull test is a simple, non-invasive procedure that can help diagnose various hair loss conditions, such as alopecia areata, telogen effluvium, and trichotillomania. It is also used to evaluate the effectiveness of hair loss treatments.
