The occurrence of pimples after shaving can be caused by multiple factors. Improper shaving techniques, such as using an unclean blade or incorrect shaving methods, may damage the skin, leading to inflammation and pimples. Folliculitis is also a common cause; shaving may injure hair follicles, which can then become infected with bacteria and develop into pimples. Additionally, improper diet and hormonal imbalances may lead to excessive oil secretion by the skin, clogging pores and forming pimples. To prevent and treat pimples after shaving, it is recommended to keep the blade clean, shave correctly, and maintain proper skin hygiene and a balanced diet. If pimples are severe, prompt medical attention is advised, along with following the doctor's recommendations for treatment.
