Shaving is a common and inexpensive way to remove unwanted hair. But shaving can cause skin irritations, especially if your skin is thin, dry or very sensitive. For a smooth shave:

• Shave after a warm bath or shower or press a
     warm wash cloth on your skin before shaving
     to soften the hair.
• Don't shave dry skin, which can cause razor burn.
     Apply shaving cream, lotion or gel before shaving
     to protect and lubricate your skin.
• Use a clean, sharp razor. If using an electric razor,
     don't use the closest setting, which can irritate the
     skin.
• Shave in the direction of hair growth, not against
     it.
• Rinse your skin afterwards with warm water.
• If irritation does occur, apply a lotion that doesn't
     contain ethyl or isopropyl alcohol. Though alcohol
     and alcohol-based products may feel cooling, they
     don't really soothe irritated skin because the
     alcohol evaporates rapidly from the skin.
