What can happen if clipper or trimmer blades are adjusted too closely?

  1. They will become dull quickly

  2. They can cut hair unevenly

  3. They can cause irritations and ingrown hairs

  4. They will create more noise during operation

The correct answer is: They can cause irritations and ingrown hairs

When clipper or trimmer blades are adjusted too closely, they can indeed cause irritations and ingrown hairs. This is because blades that are set too close to the skin can result in excessive friction and pressure during cutting, which may irritate the skin. As the blades glide over the scalp or skin, they can also pull hair rather than cutting it cleanly at the follicle level. This can lead to discomfort and the potential for hair to grow back into the skin, resulting in ingrown hairs. The other potential issues like dulling of blades, uneven cutting, or increased noise primarily stem from factors unrelated to the blade adjustment itself. While it's true that a closer blade adjustment doesn’t inherently lead to these issues, comfort and skin health can be significantly compromised. Therefore, precise adjustments are crucial for effective and safe hair cutting, promoting a smooth experience for both the client and the barber.
