The elusive “perfect” shave is something many men strive for every morning, but very often don't accomplish. According to the New Zealand Dermatological Society, pseudofolliculitis barbae -- also known as razor burn -- is an inflammation that occurs because of ingrown hairs and it is more common in men with naturally curly facial and neck hair. Instead of treating the post-shaving razor burn and red marks, prep and shave your neck correctly to prevent them from occurring.
Dampen a hand towel with hot water and hold it against your neck for three to five minutes, rewetting the hand towel as the heat diminishes. The hot water softens the skin and opens the pores, helping to prevent irritation and red marks. Shaving just after you emerge from the shower is another option.
Work an exfoliating product into the skin of your neck using overlapping circles. This will help to remove any dead skin cells and dirt. Rinse your neck with lukewarm water.
Cover your neck with a thin layer of shaving gel or cream and let the shaving cream sit for three to four minutes. Allowing the shaving cream to soften the skin on your neck helps prevent nicks or red marks. Many shaving-cream options are available, including a moisturizing product if you suffer from dry skin, or a cream that doesn't contain dyes or perfumes if you have sensitive skin
Shave your neck in the direction of the hair's growth with a sharp razor. Rinse the blade after every stroke to wash away the used shaving cream and hair accumulates in the razor and prevents you from getting a close shave.
Splash your neck with cold water to remove the remaining shaving cream and close your pores. Pat -- don't rub -- your neck dry and apply your preferred aftershave balm, lotion or gel into your skin.
