Shaving is a grooming practice involving the physical removal of hair shafts from the skin surface using an abrasive edge, such as a blade or disposable implement. Biologically, the process requires cutting hair at or near the level of the skin, necessitating the overcoming of follicular resistance and the prevention of epithelial trauma. The mechanics are highly dependent on the quality of the implement, the sharpness of the edge, and the proper preparation of the skin to reduce friction and drag. Common complications include irritation, mild inflammation of the hair follicle (pseudofolliculitis), and razor burn, which result from micro-abrasions, trapping of foreign materials, or the physical force applied during the cutting process. The technology continues to evolve, focusing on ergonomic design, blade geometry, and specialized coatings to enhance glide and reduce the incidence of dermatitis.
