It is important to avoid shaving against the grain and going over the same area multiple times to prevent irritation and the risk of ingrown hairs and boils. After shaving, only apply a fragrance-free moisturizer like Aveeno or Glaxal Base. Avoid scented soaps and gently pat the skin dry after showering before applying moisturizer. Keeping the skin hydrated is important for healing and reducing the risk of scarring. If the issue persists, it is advisable to seek further medical advice for reevaluation.
