Razor bumps on the legs are usually caused by ingrown hairs. When you shave, the razor cuts the tip of the hair making it sharp. Once this occurs, there is a chance that the hair will either grow through the wall of the hair follicle or will grow out of the follicle and curl around into the skin. In some cases, the bumps that occur after shaving are caused by the razor blade irritating the skin.
Risk Factors
The legs are one of the most common locations where ingrown hairs in females occur, notes MayoClinic.com. This condition is also associated with people who have coarse and curly hair, such as African-Americans and Hispanics. This is partially due to the fact that the hair follicle is curved. It is possible, however, for razor bumps to affect any person who shaves her legs.
Symptoms
The symptom most commonly associated with razor bumps are acne-like blemishes that are either flesh colored, red or pus filled. These bumps may hurt or itch due to the inflammation. In some cases, a red rash may also be present in the area. Darkening of the skin, also known as hyperpigmentation, is also a symptom of razor bumps.
Treatment
The exact treatment for razor bumps on the legs depends upon the cause. For razor bumps caused by ingrown hairs, applying hot compresses to the bumps will help the bumps to drain, notes MedlinePlus. Lifting the hair out of the skin if you can see part of the hair above the skin may also help. For razor bumps caused by the razor irritating the skin, cool compresses will help to alleviate the inflammation. Applying over-the-counter cortisone can help to stop itching and a topical antibiotic will minimize the risk of infection, regardless of the cause of the razor bumps. To keep the affected area cool, wear loose pants, skirts or shorts, preferably those made of breathable fibers like cotton.
Prevention
Regardless of the cause, using proper shaving techniques can help to prevent razor bumps. Exfoliate your legs and soak them in warm water before shaving. Shave using a new razor that has one blade. Use a shaving lubricant, such as shaving gel. Move your razor in the direction the hair grows, which is from the thigh to the ankle, and shave over each strip of hair only once. After you shave, rinse your legs with cool water.
Considerations
If you suffer from razor bumps each time you shave your legs, you may need to try alternative methods of hair removal. Using a chemical hair remover or electric shaver are the preferred alternatives. You can also try waxing, sugaring and plucking hair, but these methods are also likely to lead to ingrown hairs and razor-bump-like lesions.
