1. Shave,wax, or tweeze hair in the direction of hair growth. Shaving against the grain bends the hair backwards, encouraging its growth back towards the skin.
2. Moisturize the area to be shaved so that the hair is soft, and less resistant to removal.
3. Do not shave over the same area multiple times.
4. Change the razor blade, or use a new razor. A dull razor can aggravate the skin.
5. Exfoliate before or after shaving so that dead skin is removed, and therefore cannot block any hair follicles.
6. Place warm, damp towel over the recently shaved area. This will help soothe the skin.
7. All of these tips can be combined for a shaving experience that not only helps prevent ingrown hair, but is also more relaxing.
8. Some people have also found success by switching to an electric razor. These are available for women now, too.
9. Even after following the tips to prevent ingrown hairs, they may still appear from time to time. The key to treatment is to be gentle, as too much prodding may lead to infection. The red bumps that appear from ingrown hairs are very sensitive.
10. The best advice for treating an ingrown hair is just to leave it alone. It should heal on its own within a couple days.
