If you are prone to breakouts, follow these steps to reduce your chances of getting whiteheads after threading.
Wash your face before getting threading. This means thoroughly cleaning off any makeup, sunscreen, and oils to prevent these products from seeping into your newly opened pores.
After getting threaded, place witch hazel or acne astringent on threaded areas. Most salons should have witch hazel and aloe for you to place on threaded areas to prevent breakouts.
Do not touch or rub your face with your hands.
Wash your face at home with an acne-fighting scrub or foam cleanser the same evening you were threaded.
Following the four steps above will help reduce whiteheads after threading significantly.
