Shaving your head with a knife, hot water plays an important role

After testing all types of head shavers that humans make, the most advanced versions... I came to the final decision that razor and hot water are the duo that brings the best shaving experience. I followed that and tried different razors and made the choice that the 5-blade razor set from GilletteLabs is the one that gives the smoothest shave... but the important thing is that you need to warm it up and need shaving cream and foam to support it. I would like to present to you the process of shaving my head step by step as follows:

This is my hair after 4 days of not shaving my head. It's a bit long because usually 3 days or 2 days is shorter.

The first thing I do when shaving my head is soak the razor in hot water. Just use hot water from the hot water faucet in the bathroom. Or if you don't have a faucet that's hot enough, really hot, you can boil the water.

I only shower for about 5 to 7 minutes and during that time, after showering, the knife is still hot and the water is still hot. Soaking the knife in hot water is an extremely important operation, greatly affecting the head shaving experience. After testing many times, I found that hot water makes the blade when cutting through the hair many times sweeter and smoother than the knife in its normal state. I usually soak 2 because one will cool down after shaving for a while and then use the other one to continue shaving. If you bathe with warm water, it's also good because it makes your hair softer and the razor glides more gently.

Next is about shaving cream. Shaving cream plays an important role in helping the knife glide gently over the head, without damaging the scalp, so you don't have to press hard when shaving. There are many different types of shaving cream, so you can buy the one that suits your needs. I use different types of shaving cream, not foam. Because testing using foam shows that it does not do a good job of helping the knife glide over the head. When first squeezed out of the bottle, it swells and is very present on the head, you can't see the lines when scraping. But after a few minutes of operation, it collapsed again...

Need this shaving cream for the whole head

The shaving cream will stay close to your head and always stay like this while you shave.

Just swipe once or twice and it will be smooth

The cream also helps keep hair from flying around in the bathroom. I flush this into the toilet

The knife I use is GilletteLabs Heated Razor. I bought and used it from 2019 until now.

#CES19: Gillette Heated Razor in hand, warming the skin before shaving Gillette has researched that humans like to shave after warming up with warm water, a warm towel, etc. so they created a razor with a 45 or 50 degree heating element at the tip of the blade. This part will glide over the skin area that needs to be shaved right before... Tinhte.vn

After cleaning all the hair and shaving cream, the scalp is smooth like this. But we need to add one more fun step…

Oil or glue after shaving. You need to use this to help moisturize oily skin after scraping. It will help avoid conditions such as dry skin, red skin and help cover skin scratches to help avoid bacteria...

You take a small portion the size of your little finger and put it on your hand. Rub both hands evenly until it overflows. Then use both hands to apply it to your head, over and over again like a scalp massage.

Scalp becomes smoother after applying cream/oil and massaging the scalp. It's also no longer red.

Feeling comfortable and at ease. After this step, I usually brush my teeth thoroughly and then use a water flosser to make sure there is nothing left in my mouth or between my teeth. As if only our body remains intact, nothing else lingers. I use a Philips Sonicare AirFloss water flosser:

And in moderate light, I make a glass or two of Whiskey. Feel the full smell and taste of the wine going through the teeth, down to the stomach... then the feeling of calves encroaching. Please allow me not to share the next part because recently reading the comments, it seems like a lot of middle school and high school kids are coming in. So subtle.
