So why do we have dry, rough, damaged, broken, bifurcated hair?
The biggest reason is that the softeners and pigments in perm, perm and hair dye lotion have strong destructive power. In order to make hair straight, curly or colored, it is necessary to interrupt the fibers in the medullary layer of hair. When the fibers are interrupted, it can be finalized by a perm curling bar or straightener. Coloring, heating or staying for a period of time, plus styling agent to connect the fibers in the medullary layer, at this time only part of the connection, not completely connected, resulting in dry and damaged hair, in order to allow dyeing and styling agents into the hair interior, will also destroy the hair's epidermis, that is, hair. Scale tissue can cause hair scales to rise or even fall off, which is the cause of fracture, roughness and hair bifurcation.
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.

(5) Overuse of cosmetics
Especially some hair gels or stereotyped sprays may increase the greasy sensation of scalp. Moreover, some shampoos contain moisturizing ingredients, which may aggravate the problem of oil production.
Pay no attention to cleanliness
Many MMs don't wash their hair during menstruation. In fact, a menstruation usually lasts for about a week. It's no wonder that your scalp doesn't get oily without washing your hair.
Too frequent shampooing
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.
