Quick answer

Razor bumps are inflamed hair follicles caused by shaving, while ingrown hairs are hairs that curl back into the skin. Both can be prevented with sharp blades, proper technique, and post-shave care.

What causes razor bumps?

Razor bumps, also known as pseudofolliculitis barbae, occur when hair follicles become inflamed after shaving. This usually happens when a dull blade tugs at the hair, causing it to grow back at an angle and irritate the follicle. Using a sharp, clean blade and shaving in the direction of hair growth can significantly reduce the risk.

What causes ingrown hairs?

Ingrown hairs happen when a hair grows sideways or curls back into the skin instead of emerging straight out. This is more common with curly or coarse hair, but can affect anyone. Exfoliating before shaving and using a high-quality razor with multiple blades can help lift the hair and reduce the chance of it getting trapped beneath the skin.

Common myths about razor bumps and ingrown hairs

  • Myth: Razor bumps and ingrown hairs are the same thing: Razor bumps are inflamed follicles from shaving; ingrown hairs are hairs trapped under the skin. They look similar but have different causes and treatments. Use a sharp blade to prevent razor bumps; exfoliate to prevent ingrown hairs.
  • Myth: Shaving more often prevents bumps: Shaving too frequently can actually worsen irritation by not giving skin time to recover. Shave every 2-3 days and always use a fresh blade. Give your skin a break between shaves to reduce inflammation.
  • Myth: You can't shave if you have sensitive skin: With the right tools and technique, even sensitive skin can be shaved comfortably. Dermatologist-approved razors with thin, sharp blades minimize irritation. Choose a razor designed for sensitive skin and always use a moisturizing shave cream.
