So why do we have dry, rough, damaged, broken, bifurcated hair?
The biggest reason is that the softeners and pigments in perm dyeing, perm and hair dyeing lotion have strong destructive power. In order to make hair straight, curly or colored, it needs liquid medicine to interrupt the fibers in the medullary layer of hair. When the fibers are interrupted, it can be fixed and colored by perm curling bar or straightener, heated or stayed for a period of time, plus. Shaping agent is used to connect the fibers in the medullary layer. At this time, only part of the fibers are connected, not completely, which leads to dry and damaged hair. In order to let dyeing and shaping agents enter the inner part of the hair, it will also destroy the epidermis of the hair, that is, the hair scales, which will cause the scales to warp or even fall off. This is the reason for the breakage, roughness and furcation of the hair. 。
Conventional conditioners fill holes in damaged areas and cause false slippage. When the damaged parts are washed away again, the hair will still be rough and dry.
Why is hair oily more and more easily? Head oil actually comes from sebaceous glands hidden in the scalp. Sebaceous glands in healthy scalp secrete grease all the time, so sebaceous glands are also known as "24-hour power plant". Sebum secretion is regulated by the activity of sebaceous glands and the ability of sebaceous secretion. Generally speaking, normal lipid secretion can play a role in softening, protecting scalp and sterilizing; but if the secretion is too strong and there is too much lipid reaching the surface of the scalp, then embarrassing and difficult problems may arise.

Experts say that not paying attention to the cleanliness of the head can make the hair look greasy. In fact, too much cleanliness can also cause excessive fat secretion in the scalp. Because the skin feeds back on the information it receives, such as if you wash your hair too often, sebum receives a "lack of oil" signal, and thus further secretes oil. Springing amino acid shampoo can balance the scalp acidity and basicity, adjust to the normal PH value of 5.5, the most important is from the internal regulation of scalp secretion, and metabolic function.
