Looks like a rash and as the name suggests, presents an unpleasant fiery sensation.
A lack of skin preparation, a blunt blade dragged across the skin with too much pressure or occasionally, bacteria build up on an old razor.
A sharp, new blade coupled with the correct shaving cream or gel. Moisturising with an alcohol-free aftershave balm will also calm irritation.
GET OUT OF A SCRAPE
Inconvenient incisions or microcuts through several layers of skin that are prone to bleeding.
Shaving against the grain, repeating the area without extra shaving cream, using too much pressure or a blunt blade.
Always shave with the grain, (the direction of hair growth) remembering that not all the hair grows the same way. Using gentle strokes, a fresh blade and softening the area with a cleanser or exfoliator first will help prevent mishaps.
Spots of inflammation that can look like pimples.
Hairs curling back under the skin rather than growing straight.
Exfoliating regularly will release any trapped hair over time. If you've got a steady hand and can see the hair 'loop,' you can flick it out - but plucking it will make the situation much worse!
