It is common sense to use shampoo when washing your hair, but you don't have to. Shampooing with hot water is called hot water shampoo, but it is still a good substitute for shampoo. You can get shiny hair with Yu Shan.
Effect of hot water shan
Celebrities who play hot springs include Tamori, Masaharu Fukuyama, Laura and Anne Nakamura. You also do beautiful men and women. The effect of shampoo on hair is not always good, and you can see from the fact that it must be supplemented with a conditioner. Hot water alone removes a lot of dirt from your hair, so you don't need a shampoo that can cause your scalp to dry out or cause dandruff. It also has the effect of reducing hair loss for men. If you remove too much dirt, your body's barrier function will drop, so it is popular overseas as a no poo exercise. I'm glad that it doesn't cost shampoo.
Hot water shan method
The specific method is a little troublesome, but please note that if you do not do this, you will lose the sense of cleanliness. First of all, brush your hair and wash it thoroughly with a shower of lukewarm water at about 38 ° C so as not to damage your hair. At this time, massage with the pad of your finger to loosen it. Hair that is not protected by conditioner is weak, so be sure to dry it with a hair dryer. If this is not done, it will cause an odor.
Shampoo has a short history
Looking at the history of hair washing and shampooing, I used to have no habit of shampooing, and in the 1700s I used to massage my hair with perfume oil in India, which is different from shampooing. It wasn't until the 1900s that shampoos with surfactants that remove dirt were used as they are now, and it's surprisingly recent. I haven't used it before, so it may not be a special need.
In the days when there was no shampoo, in Japan it was only washed once a month with gliopeltis or rice bran, and most of the time it was combed to remove dirt. Even when shampoo started to become popular in Japan, it was a catch phrase, "Shampoo once every 5 days," and I never washed it every day. When shampooing, a phenomenon called percutaneous toxin, in which toxins in the shampoo penetrate from the scalp, occurs, and harmful substances are absorbed from the skin. This causes irritant dermatitis, eczema, and dryness.
