Why do I get red spots and itch after shaving?

Some people will experience itchy skin and red spots after shaving. This is mainly because the body's skin reacts adversely after hair removal and causes discomfort. Generally, it is caused by allergies. Body hair has certain functions and effects. It can regulate body temperature and avoid the harm of dust and some harmful substances. When shaving occurs, such symptoms may occur.

The role of hair

Hair has many functions. It helps regulate body temperature and is also an organ of touch. When we lightly touch the surface of the body, the roots of the hair will move slightly. This movement will be immediately intercepted by the small branches of nerves surrounding the hair shaft and then transmitted to the brain via the sensory nerves. Each hair is connected to one or more sebaceous glands composed of alveoli arranged in secretory ducts.

When we exercise, the sweat on the forehead will flow down. If we don’t have eyebrows, the sweat will flow directly into the eyes, blocking our vision and hurting our eyes... The armpits and pubic areas are often rubbed, and armpit hair and pubic hair can reduce local friction and help the dissipation of sweat. For women, pubic hair mainly serves to resist germs and keep the genitals breathable.

What to do if you have skin allergies

1. Keep your skin clean. Spring is windy and dusty. The dust mixed with the abundant sebum secretion can easily cause rough skin. Therefore, you should always keep your skin clean. You can use mild facial cleanser and lotion to help kill bacteria, clean and soften the skin.

2. Do not change the cosmetic brands you are used to at will, because the skin needs to adapt to the new climate and is in a period when its ability to resist and adapt to the external environment is relatively weak. If you change brands at will, allergies are likely to occur.

3. Pay attention to skin moisturizing at all times and enhance skin resistance. You can choose refreshing and hydrophilic skin care products. Skin care products with high oil content should be used as little as possible in winter.

4. Pay attention to the impact of wind and sand on the skin. People with sensitive skin should pay special attention to using scarves, masks, etc. to cover themselves when going out to avoid being blown by the wind.

5. Eat more fresh fruits and vegetables, and less irritating foods that may easily cause allergic reactions, such as seafood, bamboo shoots, etc.
