The red bumps or can be due to many factors, and each person responds different to shaving and all hair removal techniques. I tried and researched a lot of things in the past decade I have shaved my whole body. If you have any questions, just write to me.
It's technically "folliculitis" or inflammation of the hair follicle. There's ways to reduce it with the technique of shaving, and what you do after shaving. It's common, but obviously not wanted for looks, comfort, or health.
Some tips if you wish:
- If your hair grows out longer, first use the trimmer like you did to make it short.
- Take a shower first. Your hair and skin need to be moist. If you take a wet cloth and use that to dampen what you shave first, it likely is not enough. This is one common reason for red bumps, cuts, and razor burns.
- Use a good razor that works for you. Blades might cost.
- Make sure your skin is wet and slippery, lubricated by shaving gel or cream at all times you are shaving. Reducing resistance is the whole point.
- Shave without pressure, let the razor blade shave without force.
- First shave in the direction of the hair. Make sure your skin is still wet and lubricated or apply more gel or cream. (If your skin can tolerate it and the blade is high quality, second shave in the opposite direction, against the hair growth, to make you skin really smooth. This is controversial, but is how many guys get a smooth shave.)
- Try not to go over any area of skin more than once or a couple of times. If the blade isn't getting it, just stop. This is often what causes "razor burns" and "bumps," including those red spots.
- Don't get frustrated. Shaving sounds easy and is but takes a while to learn how each part of your body responds, and there's lots of different areas from the chest to pubes.
- It may not look or feel like it, though skin is super sensitive right after you shave. Wash it off gently and thoroughly, or better, go in the shower to quickly rinse off. Pat the skin dry rather than rubbing with a towel.
Right after shaving:
Some people use "Tend Skin," a product that is made specifically for such problems with shaving. It will reduce the redness and bumps or get rid of them, even ingrown hairs sometimes. Not cheap but you use hardly any. Check the expiration date when buying, and don't use it after that date. If you are allergic to aspirin, you cannot use this product, which contains a lot of aspirin. It has a medicinal smell (alcohol), and may sting a little when applied), but it quickly goes.
1. First you MUST wait for the skin to dry before applying the liquid.
2. At this point, put a small amount on a cotton pad or ball and dab the areas of your skin that are prone to red spots, problems. If the problem goes as you get more used to shaving, you may not need to use this, or only once in a while.
3. Don't douse your skin with the liquid or rewet the areas with it several times.
4. Follow the directions, and reapply two times a day or what it says.
5. It will evaporate from your skin fast, but wait at least few minutes until your skin is good and dry before using moisturizer.
6. Apply a moisturizer if you wish. Don't apply too much, particularly to areas that are not going to get much air, or where the skin will be touching skin. This is likely one reason why irritation appears in the crotch or near it sometimes. The moisture can cause rashes, as anyone who cares for children knows, which is why some men use powder on the crotch, ass and feet. It's true what others wrote about moisturizing the skin. You just have to watch your own body how it responds. I like to moisturize but am careful in areas that are prone to rashes.
