What is the result of using improper techniques with razors or trimmers?

Using improper techniques with razors or trimmers can lead to the formation of ingrown hairs. When hair is cut too short or the hair follicle is damaged during shaving or trimming, the hair may grow back into the skin rather than outward. This occurs particularly if the hair is curly or coarse, as these types can easily bend back into the skin. Ingrown hairs can lead to irritation, inflammation, and sometimes infection, which underscores the importance of using proper techniques when cutting or styling hair.

In contrast, other options do not relate to the specific consequences of using improper techniques. Improved hair growth is not a product of technique, and minimal styling does not directly result from bad razor or trimmer use. Additionally, better control is typically associated with correct handling and technique, rather than improper use. This emphasizes why maintaining proficiency in using razors and trimmers is crucial for avoiding complications like ingrown hairs.
