When you have sensitive skin, common shaving mistakes are no joke. A rushed shave or a poor technique can quickly lead to ingrown hairs, razor bumps, and the dreaded razor burn. If you’ve ever wondered, ‘Why do I get razor bumps?’ or struggled to avoid shaving irritation, the answer often lies in a few common shaving mistakes.
Bad grooming habits can cause irritation by damaging the surface of the skin and trapping hair follicles underneath. These poor practices can lead to different types of irritation, such as razor burn, razor bumps, and ingrown hairs.
Up to 57% of people experience redness (erythema) and irritation after shaving.1 Razor burn can be caused by the following bad grooming habits2:
To avoid shaving irritation, make sure you’re prepping your skin before hair removal and are using a clean, sharp blade to reduce friction.
Razor bumps (pseudofolliculitis) are the inflamed, red spots caused by ingrown hairs after shaving.3 They’re a sign that you might be:
Ingrown hairs after shaving occur when you cut too close to the skin, use a dull blade, or shave too regularly. The tip of the hair curls back in on itself, causing it to grow under the skin and creating itchy, painful bumps.4
Understanding these common shaving mistakes you’re making is the first step to steering clear of them for smoother hair removal. Now you know what not to do when shaving, you can move on to tips for a better shave.
Reduce irritation when shaving by carefully prepping your skin, using the right tools, and following a good technique. Soothing aftercare also reduces the chance of post-shave issues, like dryness and ingrown hairs.
Get started by following these preparation tips for a better shave:
Technique is just as important as preparation. Follow these steps for smooth skin and avoid shaving mistakes that lead to irritation:
To reduce irritation, opt for a shaver that’s designed for ultimate skin comfort, like the Philips i9000 Prestige Ultra. A wet and dry shaver, it gently lifts hairs at the root to reduce contact between the blade and the skin, all while maintaining a close cut for smooth hair removal.
Advanced skin protection around the blade makes for smoother shaves, while AI-powered feedback helps you adjust your technique for efficient hair removal.
With a fleet of sensitive-skin features, the Philips i9000 Prestige Ultra is suitable for hairs that grow in different directions. The flexible head adapts to your face contours for a clean and precise shave.
Shaving with the grain is generally best if you’re prone to irritation, as it reduces friction and the risk of razor burn or ingrown hairs. Shaving against the grain can give a closer result, but it’s more likely to irritate sensitive skin, so it’s better saved for when your skin tolerates it well.
Shaving without preparation leaves hair stiff and skin unprotected, which increases friction and irritation. Proper prep helps soften hair and create slip, allowing the blade to glide more smoothly and reducing the risk of razor burn.
Rashes after shaving are most commonly a form of razor burn, caused by friction between your skin and the blade. This can happen if you’re using a dull blade, your skin isn’t properly prepped, or you're shaving with poor technique. Try using a shaving cream or lotion before hair removal and shaving in short, light strokes.
From razor burn to pesky ingrown hairs, post-shave irritation is caused by some common shaving mistakes. By remembering what not to do when shaving (like using a dull blade and pressing too hard), prepping your skin beforehand, and using the right shaving tools, you’re on your way to a smarter, smoother shave that protects your sensitive skin.
