Description

Shampoo composition comprising menthol microcapsules {A shampoo composition comprising menthol microcapsule}

The present invention relates to a shampoo composition for preventing hair loss, and more particularly, to a shampoo composition for preventing hair loss comprising a shampoo base and menthol microcapsules.

It is known that hair loss is caused by an unbalanced diet, excessive drinking and smoking, drug use, lack of sleep, stress, childbirth, menopausal disorders, frequent perms and dyeing, and hormonal imbalance.

Androgenetic alopecia caused by male hormones and heredity usually begins in the 40s and 50s, but in severe cases, it begins right after puberty and lasts for decades. Hair loss mainly starts at the top of the head and gradually progresses to the entire head. In the case of men, hair loss is predominant in the hairline of both temporal regions and the top of the head, and in women, the hair boundary of the facial scalp is generally well preserved. It is rare for complete bald spots to form.

As hair loss progresses due to these various causes, the number of hair loss increases as the hair on the crown and forehead begins to thin and lose strength, and if this phenomenon continues, the hair loss becomes severe enough to be directly observed with the naked eye.

Methods for treating hair loss include topical application agents, oral medications, health supplements, gene transplant surgery, hair transplant surgery, etc., but these methods have a limited range of use and do not continuously prevent hair loss.

In addition, the effect of drug treatment is also temporary, and there is a side effect of accelerating the production of scalp or sebum.

In order to solve the above problems, it is necessary to develop a shampoo that not only prevents hair loss, but also generates new hair, thickens thin hair, and has a normal hair cycle.
