Steam the face or area with a warm towel for about five minutes.

Sterilize a pair of needle-nosed tweezers with rubbing alcohol and individually lift each ingrown hair out of its follicle. Wipe the area with alcohol afterwards.

If needle-nosed tweezers are not available, wipe a pin or needle and the ingrown area with rubbing alcohol and carefully release the hair using the tip of the needle only.

Never jab the needle into the skin. After the hair is released, wipe the skin with alcohol again.

Using ordinary tweezers to release hair might cause a hunk of tissue to be plucked along with the hair.
