Threading hair is considered okay, however, it can cause potential side effects like redness, itching and irritation, especially for sensitive skin people. Threading removes hair from the root, using twisted cotton or polyester thread, mostly used for upper lips, eyebrows and chin hair.

The threading technique pulls out hair directly from the root for shaping eyebrows and tidying up your chin. The threading process is more precise for people as it gives results for a longer time.

However, threading has potential side effects especially for sensitive areas like upper lips, causing redness, itching and even swelling. Also, in some cases, uneven ingrown hair can cause you more discomfort and sometimes acne.

Overall, threading hair is relatively safe, but make sure a qualified or experienced professional does the procedure. You can consult a healthcare professional before trying any new hair removal method.
