What causes frictional alopecia?

It is caused by repeated rubbing or pressure on the same area of scalp, commonly from tight headwear, helmets, glasses arms, straps or persistent scratching. Unlike pattern baldness, it comes from external friction rather than hormones or genetics.

Is frictional alopecia permanent?

Usually not. It is a non-scarring type of hair loss, so the follicles are irritated rather than destroyed, and hair generally regrows once the friction is removed. Only friction sustained over many years risks more permanent damage.

Can frictional alopecia be reversed?

Often, yes, especially when caught early. Removing the source of friction and giving the follicles time to recover is usually enough for hair to grow back, since the follicles themselves typically remain intact.

How do I treat frictional alopecia?

The main treatment is removing the cause, loosening or changing whatever rubs the scalp, then allowing time for regrowth. If hair does not return after the friction is gone, an assessment is worth arranging to rule out other conditions.

How is frictional alopecia different from pattern baldness?

Frictional alopecia appears as a defined patch that matches a point of contact and often recovers when the friction stops. Pattern baldness follows the hairline and crown in a predictable shape, is driven by hormones and genetics, and does not resolve on its own.
