What is the most common cause of razor bumps?

1. Excessive shaving

2. Ingrown hairs

3. Poor quality razors

4. Allergic reactions

The correct answer is: Ingrown hairs

Razor bumps, also known as pseudofolliculitis barbae, are primarily caused by ingrown hairs. This condition occurs when hair grows back into the skin rather than outward, leading to inflammation and the characteristic raised bumps. When facial hair is shaved closely to the skin, particularly in individuals with curly or coarse hair, the hair can curl back towards the follicle instead of growing outward. This is especially prevalent in areas where the hair is coarse or tightly curled, making ingrown hairs a frequent issue. While other factors like excessive shaving, poor-quality razors, and allergic reactions can contribute to skin irritation or discomfort, ingrown hairs are specifically identified as the root cause of razor bumps. Therefore, understanding the nature of hair growth and the shaving process is crucial in preventing these bumps, making ingrown hairs the most significant factor in their development.
