Use fresh razors. Razors that have been used many times become dull and grow bacteria - two problems that significantly worsen razor burn. Use new razors every two weeks or five uses, and clean your razor well after every use.
Go in the right direction. Shave with the grain of the hair in shorter, deliberate strokes. Shaving against the grain increases the odds of ingrown hairs, irritation, and inflamed skin. Long strokes often cause one to press down too hard on the skin, increasing razor contact and making razor burn more likely.
If you need a closer shave go across the grain.
Essentially the blades used against the direction of growth (grain) lift the hair up too much the next cuts, then the follicle retracts too far into the epidermis. This may lead to spots, blemishes and ingrowns.
Shave at night. Shaving your hair in the morning typically precedes the application of some product - for example, deodorant after shaving your armpits. Additionally, throughout the day you are likely to sweat and come into contact with bacteria and and toxins from the air. The combination of all these things with your freshly shaved face greatly increases the likelihood of razor burn. Prevent this by simply shaving at night before heading to bed, where you will be less likely to dirty the area
Shave in the shower. Even when you dampen your skin prior to shaving, your hair doesn’t have enough time to soften and become easier to shave. Take a hot shower and shave after a few minutes or if it's a smaller area some warmed aloe vera gel; the heat and moisture will soften your hairs and make them easier to remove. Don’t wait too long though, as waiting ten minutes or longer will swell up your skin and leave you with a bit of stubble after you’ve cooled down and dried off.
Hair naturally plumps up with water - as it will absorb up to an extra 30% of its moisture in volume. This makes hair weaker, softer and easier to cut! Who knew?
Clean your razor regularly. If you shave without rinsing your blade, you might be increasing your chances for razor burn. Buildup of hair and product in the blades of your razor forces you to push down with more pressure on subsequent swipes, making it more likely that you’ll irritate or cut the skin. Thoroughly rinse your razor after every pass you take on your skin to remove all hair and buildup between the blades. Drop some hand alcohol gel on the blades to keep them corroding and getting ragged and ward off bacteria.
Splash your skin with cold water. After every finished shave, splash your skin with cold water to close up the pores. This will constrict the skin and help to close any small cuts or ingrown hairs that are forming.
Cleanse with Hand Sanitiser after the final rinse. Blades last much longer than most people think. The apparent dulling of the blade is due to the formation of microscopic "teeth" on the edge, made up of mineral crystals from the water. These drag against the skin, causing the blade to grab and producing cuts and much of the razor burn. The alcohol in the gel will displace the water and the minerals within it, and evaporate without leaving residue. Store the razor with the blade edges upward.
Use a blemish treatment gel. These gel contain salicylic acid which will help to kill bacteria and reduce the likelihood of razor burn. Rub the area you are going to shave with a gentle face wash and rinse off prior to shaving.
Use Quality shaving gel. Never dry-shave with just water, and avoid using a shaving cream that can clog pores. Instead, apply a coat of shaving gel to the area you will shave, and rinse your razor after every swipe. The gel will help to protect your skin from the blades without clogging your pores
Apply aloe vera. After you finish shaving, put a little aloe vera gel on the area. This will help to soothe irritated skin and prevent razor bumps. Allow it to set for 5-10 minutes before rinsing off with cool water and patting dry with a clean towel.
Use an oatmeal mask. Oatmeal has been used for decades as a remedy for skin irritants, and works great for razor burn. If you know that you are prone to razor burn or are already experiencing the mild rash, blend oatmeal with a bit of milk and dab it onto your skin. Leave it for 5-10 minutes before rinsing off with warm water
Put on some sour cream. Although this may sound odd or gross, sour cream contains nutrients that are great for healing razor burn. Additionally, the cold cream feels good on irritated skin. Swipe on a dollop of sour cream to the area you have finished shaving, and then rinse off after about 10 minutes.
Check for allergens. Look through all the products you apply to your skin to see what they’re made of. There might be something in the ingredients list that you are allergic to, and therefore are reacting to with a rash. Cut out all your skin products for a few days after shaving, and slowly incorporate them back in one at a time to find out which one is the culprit.
