When it gets hot it is so tempting to pull your hair into a ponytail to keep it off your face and neck, but if you are exiperiening thinning at the hair line your pony tail could be the cause. Traction alopecia is the technical name for tension hair loss—simply, localised hair loss caused by damage to the hairs' roots from constantly pulling hair too tight in the same direction. Traction alopecia occurs gradually, and is merely a cosmetic issue as hair around the points of pressure begins to thin. However, severer forms of traction alopecia can cause permanent localised hair loss. The condition is not a disease, and has no medical symptoms other than perhaps a headache caused the hair being pulled too tight. To repair the hair line take a break from the ponytails and apply our Scalp treatment to the scalp.
