Description

TECHNICAL FIELD

[0001] The present application belongs to the field of daily chemicals, and particularly relates to a cleaning and mite-removing hair care composition containing orchid root oil. BACKGROUND

[0002] In daily life, hair and scalp are exposed to the outside for a long time, are easily affected by ultraviolet rays and air pollutants, and are easily damaged by behaviors such as excessive cleaning, hair perming and hair dyeing. Damage to the scalp is easy to cause excessive secretion of sebum, make the microenvironment of the scalp disorder and breed bacteria and mites, and further cause symptoms such as dandruff, dermatitis and hair loss. Damage to the hair is easy to cause decomposition of protein in the hair, and the hair loses nutrition, causing rough and yellowish hair, dry and easy-to-break hair.

[0003] In order to protect the health of hair and scalp, consumers usually choose hair care products to clean and care the hair and scalp. However, some additives in the hair care products have a damaging effect on the scalp, and long-term use or incomplete cleaning after use is easy to cause the additives to remain on the scalp, aggravate the disorder of the scalp microecology, further breed bacteria and mites, and have an adverse effect on the health of the scalp and hair. In addition, traditional hair care products generally use additives such as silicone oil and silicone fat to make the hair smooth and lustrous. Although this can provide a certain smoothing effect in a short time, if used for a long time, the silicone oil will deposit an oil film on the hair, the hair becomes thick and greasy, the scalp is thick and not dry, and such hair care products do not solve the fundamental problems existing in the scalp environment and the hair, and the health problems of the hair and scalp still exist.
