Using a sharp blade and shaving with the hair growth is crucial in preventing cuts and nicks during shaving. A sharp blade glides smoothly over the skin, reducing the chances of tugging or pulling on the hair, which can lead to irritation or injury. Shaving in the direction of hair growth minimizes the risk of cutting the hair below the skin level, which often results in ingrown hairs and additional skin issues.

In contrast, shaving against the direction of hair growth increases the likelihood of cuts, as the blade encounters hair resistance and can easily slip, leading to nicks. Using a dull blade would not only make the shaving process more difficult but also require more pressure, potentially causing skin damage and discomfort. Excessive pressure can indeed lead to cuts and irritation, as it forces the blade into the skin rather than allowing it to glide smoothly.

Thus, employing a sharp blade and following the natural direction of hair growth is the most effective technique for achieving a clean shave while ensuring the safety and integrity of the skin.
