# Hairline Acne

## Quick Summary

Hairline acne is clogged-looking or pimple-prone skin along the forehead, temples, or scalp edge. Hair styling products, sweat, hats, and incomplete cleansing can all be part of the pattern.

## Causes

Heavy pomades, oils, leave-in conditioners, sunscreen or makeup residue, hats, helmets, sweat, and friction can contribute. Itchy, scaly, painful, spreading, or pus-filled bumps should be checked rather than treated as simple acne.
