What is a common cause of ingrown hairs?

1. Regular use of hair products

2. Improper shaving techniques

3. Using the wrong type of razor

4. Frequent haircuts

The correct answer is: Improper shaving techniques

Improper shaving techniques are a common cause of ingrown hairs. When hair is shaved too closely or in the wrong direction, it can cause the hair to become trapped beneath the skin's surface as it grows back, leading to irritation and inflammation. Techniques such as shaving against the grain or using excessive pressure can exacerbate this issue, causing the hair to curl back and penetrate the skin instead of growing outward as intended. Proper shaving methods, such as shaving in the direction of hair growth, using a sharp razor, and keeping the skin well-hydrated, can significantly reduce the likelihood of developing ingrown hairs. Other options, while they may contribute to skin irritation or hair health, are not as directly linked to the occurrence of ingrown hairs as improper shaving techniques are.
