1. Reasons for hair on the crown of the head: Do you know why humans lost all their hair (in the process of evolution)? This is because the established theory of evolution prioritized body temperature regulation through sweating and promoted cerebral development. To put it bluntly, the skin shifted its weight from the dominant state of hair follicles to the development of sweat glands. Where the hair was gone, the keratin became thicker (instead). On the other hand, the top of the head, which protects the brain, was blessed with a rich vascular network "by chance" and hair remained... Conversely, hair that is only left by chance becomes difficult to maintain if the vascular network that delivers nutrients to hair matrix cells changes (due to aging, etc.). 2. Blood circulation on the skin. This is the "iron plate": If it was a "coincidence" that hair remained on the top or back of the human head, you should pay attention to blood circulation. Nabocal, whose main product is commercial massage products, has realized the benefits of massage to promote blood circulation. This is the basis of health and can be applied to hair (the environment of the scalp). However, the head with hair has few muscles and is covered with hard fascia. It is a structure that makes it difficult to transmit "pressure" from the outside. Therefore, Navocal proposes products that perform massage without damaging the skin. It is scalp care when it is soaked in water and mixed with sticky ingredients. 3. Using "seaweed" is the wisdom of the Japanese: Navocal uses whole seaweed in the manufacturing process. The polysaccharide component derived from seaweed acts like a massage gel. Moreover, the characteristic of Navocal formula is that it is a formula with minimal surfactants, so it is considered for long-term use. Back in the Edo period, seaweed was heavily used to remove dirt. It does not damage the hair, and by physical action, even absorbs oil. Navocal has put together a shampoo as a modern item that makes use of such a long-standing natural ingredient to achieve scalp massage. Please take advantage of the time you spend washing your hair as a scalp massage habit. [Explanation of background and premise] A long-selling commercial nabocal cosmetics product is seaweed shampoo. Funori, which was heavily used as a hair shampoo in the Edo period, is boldly used. Basically, you can just wash your hair with water. However, the common people in the Edo period began to use camellia oil to tie their hair. In modern terms, it is a hair conditioner such as hair oil and pomade. In other words, the use of oil began and the need for shampoo was born. However, with the advent of surfactants, washing hair becomes closer to the act of "damaging". Use oil, use strong cleaning agents, damage the hair. This "negative cycle" will follow. We advocate going back to the origins once here. [How to use] Rinse your hair and scalp thoroughly with warm water. Pick up an appropriate amount (7 for long hair, 3 pushes for short). Apply to your hair and scalp, blend it into the entire area until you feel a slight lather, and wash your scalp as if it were rubbing. You can massage for a long time. Use the pads of your fingers to loosen the temporal, frontal, and back of the head. Finally, rinse lightly.
