When a person pulls the skin to ensure a neat shave, the skin expands. However, the moment he or she releases the skin it contracts covering the hair follicles that he or she cut. After a few days, the hairs start growing into the skin.
If an individual applies too much pressure when shaving he or she can end up cutting the hair beneath the surface, resulting in the development of ingrown hair. Some of the reason a person might apply too much pressure include using a very light shaver or using a shaver with a blunt blade.
Shaving against the hair grain will indeed provide a quicker and closer shave. However, it allows for the cutting of the hair beneath the skin. When the hair resumes growing, it grows into the skin follicles.
Before shaving, it is important to prepare the skin adequately for the exercise. Use of warm or hot shower helps to soften up the skin tissues and open up the pores, making the shaving smooth and effortless. However failure to do so exposes the skin and hair to high possibilities of developing razor bumps and Ingrown hair.
