Night caps have recently been attracting attention as a hair care item. By reducing the friction between hair and bedding, you can expect a hair care effect! And it's been a topic since around 2021.

At the same time, we have seen an increasing number of nightcap users complaining that they can easily take off their nightcaps, or that they find it difficult to fall asleep because their hats bother them.

What does it mean to take care of your hair while you sleep?

Why should you use a nightcap or a silk pillowcase in the first place? The answer lies in "friction".

hair friction damage

No matter how hard you try to take care of your hair before going to sleep, when you wake up your hair is dry and unruly. This phenomenon has happened every morning since I was born, so it's too natural for me to question it, but there's always a reason behind the results. Of course, there are reasons for dryness and peculiarities.

The bedding and hair come into contact with each other, and the weight of the head and rolling over create friction, which lasts for as long as you sleep (about 7 hours on average!). The friction causes the cuticle to open and peel off, allowing the moisture inside to flow out. Your hair gets dry while you sleep, and the open cuticles make your hair feel rough to the touch.

Items to prevent that are night caps and pillow covers!

Do nightcaps and pillowcases really work?

I don't think you can trust anything written by the author who is developing the nightcap, so I would like to quote my impressions from twitter!

What is the difference between a nightcap and a silk pillowcase, effectiveness, ease of use, and price?

silk pillowcases and nightcaps

Anyway, I think you understand that it is better to reduce the friction that continues to be added to your hair while you sleep, but in fact, the mechanism of reducing friction is different between a nightcap and a silk pillowcase.

  • NightcapBy covering and fixing hair with a hat, friction with the pillow is reduced.
  • Silk pillowcase The fabric of the pillowcase is made of soft, fine-fibered silk that does not generate static electricity, reducing the friction between the hair and the pillow.

In this way, the fact that the mechanism for reducing friction is different also results in different effects.

I put together a table that can be listed for each item, such as friction, dryness, and beautiful skin effect, to see what kind of effect can be obtained from each!

ease of use

It takes some time to get used to it. Depending on the item, it may come off easily

Although it cannot be protected from wind and air drying, it does not dry hair compared to general pillowcases due to the humidity control function of silk.

comfort

You may be concerned about the feeling of tightness, but by bunding your hair, it will not cling to your neck or shoulders.

You can sleep with a smooth and comfortable touch

beautiful skin effect

The out-bath treatment applied to the hair does not transfer to the skin, so it is also good for preventing rough skin.

Friction between the face and the pillowcase is also reduced, so it is less likely to cause rough skin and wrinkles on the pillowcase caused by friction.

price relatively inexpensive The area of ​​the fabric is large, and it tends to be more expensive than a nightcap

Night cap is recommended for such people! & I do not recommend it to such people!

So far, we have looked at the differences between nightcaps and silk pillowcases in detail, but in the end, we will summarize what kind of people are recommended for nightcaps and silk pillowcases, and for whom they are not recommended. .

Night cap is recommended for such people

  1. People who are dexterous enough to do simple hair arrangements → It is not OK to wear a nightcap, but if you have long hair, it is important to put your hair in a hat so that it does not go against the flow.
  2. People who want to protect their hair not only from friction but also from dryness →Pillowcases are not suitable for preventing dry hair compared to nightcaps that completely cover the hair.
  3. For those who want to prevent the out-of-bath treatment from sticking to their face → Since the hair is put away in a nightcap, the out-of-bath treatment will not be visible on the face and neck!
  4. For those who want to keep their hair from clinging to their necks and shoulders → Hair is gathered in a nightcap
  5. People who want to try hair care while sleeping at a low price → Compared to pillowcases, nightcaps are cheaper and easier to obtain! It is also sold at 100 yen and 300 yen

Nightcap is not recommended for these people!

  1. People who sweat → sweat at night anyway! For those who say, the hair and scalp get damp in the night cap, which not only causes rough skin and bacterial growth, but also makes it easier to get into bed. Wearing a cap is meaningless, or rather has the opposite effect, or makes you bald, the developer of the nightcap thoroughly explains!
  2. People with a flat back of the head (cliff) → No matter what shape of nightcap you choose, there is a high possibility that it will be easy to take off.

Please consider using a pillow cover.

Next is about silk pillowcases.

As an author, I would rather recommend silk pillowcases than using regular pillowcases, but I will compare them with nightcaps!

Silk pillowcases are recommended for these people!

  1. For those who get bored → A pillow cover that can be easily continued is more suitable than a nightcap that takes a little effort every night ◎
  2. People who don't like tightness → Most nightcaps have a certain amount of hold to prevent them from coming off. If you're looking for a sense of liberation, this pillow cover is for you!
  3. People who sweat a lot → Night caps cover your head, so it's especially hot from spring to summer! It seems that there are many people who feel it. You can sleep comfortably all year round by using a nightcap in autumn and winter and a silk pillowcase in spring and summer.
  4. I think there are many people who are resistant to the appearance of nightcaps, and that there are many people who are resistant to the appearance of nightcaps, and although there are more types of nightcap designs for men → nightcaps, most of them are granny-like or girly. will be split. If you have a pillow cover, you can feel free to take it in!

In addition to this, silk pillowcases are also recommended as housewarming gifts or paired gifts such as wedding gifts.

Silk pillowcases are not recommended for these people!

  • People who sleep poorly → If the head falls out of the pillowcase, the effect cannot be expected. By the way, if you use silk sheets and pillowcases, the pillow will slip and your neck and head will not be stable, so I do not recommend it.

For those who have trouble sleeping, we recommend using silk cotton (a fabric that combines silk and cotton) instead of 100% silk pillowcases, or pillows with a non-slip cotton backing.

Also, people who sleep in a place where air conditioning blows directly cannot expect a dramatic improvement in dry hair. How about blocking the wind or introducing a humidifier?

summary

I introduced it at the beginning, but let's review it again.
