What are the red spots you see after shave?

Red spots or razor burn that you see after shaving are known as pseudofolliculitis barbae (PFB). These appear as tiny, red, itchy bumps that develop as the shaved hair tries to grow back into the skin instead of emerging from it. Commonly seen in people with coarse or curly hair, razor bumps are more prevalent in areas subjected to frequent shaving, like the face and neck.

Here's what causes PFB:

- Ingrown hairs: Shaving cuts the hair shaft across. When the shaft is coarse or curly, it might have difficulty penetrating the skin's surface, leading to ingrown hairs.

- Follicle irritation: Shaving can irritate the hair follicles. This can cause inflammation and redness, leading to the formation of razor bumps.

- Infection: In some cases, the hair follicles can become infected, leading to the formation of pus-filled pimples or boils.

These red spots usually disappear on their own within a few days or weeks. Here are some tips to prevent razor bumps:

- Prepare your skin: Wet your skin with warm water before shaving to soften the hair and reduce the risk of irritation.

- Use a sharp razor: A dull razor can cause more skin irritation and increase the likelihood of ingrown hairs. Replace your razor blades frequently to ensure they are sharp.

- Shave in the direction of hair growth: Shaving against the grain can increase the risk of ingrown hairs. Instead, shave in the same direction as your hair grows.

- Avoid shaving too closely: Shaving too closely can increase the risk of irritation and ingrown hairs. Leave a small amount of stubble to reduce the risk of razor bumps.

- Moisturize your skin after shaving: Moisturizing your skin after shaving can help soothe the skin and reduce irritation.

- Consider using a shaving brush: A shaving brush can help to lift the hairs and allow for a closer shave without causing as much irritation.

- Use an exfoliating scrub: Exfoliating your skin regularly can help to remove dead skin cells and reduce the risk of ingrown hairs.

If you experience severe razor bumps or they do not go away on their own, it is important to see a dermatologist. They may recommend additional treatment options, such as medicated creams or laser hair removal.
