In the modern society that emphasizes beauty, various studies are being actively conducted around the world to treat hair loss and promote hair growth of men or women who suffer from severe mental pain due to genetic or environmental hair loss.

There are about 100,000 hairs in the human body, and each hair repeats growth and degeneration through different cycles. The hair has a growing growth period (Anagen), a degenerative period (Catagen) that slows metabolism while maintaining the shape of the hair and the hair papilla is contracted and the hair follicles are contracted gradually so that the hair roots are pushed upwards and the hair follicles become smaller ( Telogen) is repeated in three phases, which can vary in terms of nutrition, medical history, heredity, constitution, hormone secretion or aging.

There are many reasons for hair loss. Androgenetic alopecia due to androgenic secretion and genetic influences; Alopecia areata due to autoimmune abnormalities due to stress; Restless hair loss after delivery due to hormones such as estrogen in late pregnancy; Hair loss due to malnutrition and metabolic disorders; Hair loss due to abnormal scalp environments such as skin diseases, keratin and dandruff; And hair loss by stimulation of the scalp through chemical treatment such as staining or perm.

Recently, as biotechnology is further developed, new cosmetic raw materials are being developed by separating pure microorganisms from various microorganisms using fermentation technology. However, depending on the microbial conditions, different types of substances were made, and there was a problem such as the smell of microorganisms. Recent research is using a method to separate the core pure enzymes that are responsible for the fermentation of microbial fermentation and develop them into new cosmetic ingredients. However, it has been known that there is an efficacy effect on hair loss prevention and hair growth in relation to hair and scalp, but the effect is still very weak.

In addition, conventional tonic formulations having an effect on hair loss prevention and hair growth may flow down to the scalp and cause eye irritation or irritation. However, recently released foam type formulations do not flow down, but have a sticky and damp feeling, which tends to reduce the fresh feeling of use on the scalp.

Therefore, there is an urgent need to develop compositions that are effective in improving ease of use and ease of use, relieving irritation to the scalp, and maintaining hair growth periods for a long time to prevent hair loss and promote hair growth.

Accordingly, the present inventors have provided an anti-hair loss and hair growth effect, and solved problems such as scalp side effects to develop a composition that can provide a stimulating effect when used in hair and scalp, gel type formulation using a thickener The fermented extract of green tea or soybean was found to alleviate the scalp irritation and to impart hair root strengthening, hair loss prevention and hair growth promoting effect and completed the present invention.

Accordingly, an object of the present invention is to improve the convenience of use, to relieve scalp irritation, to promote the induction from the resting phase to the growth hair cycle and to maintain the growth hair cycle for a long time to strengthen the hair roots and prevent hair loss and hair growth promoting effect And to provide a composition for improving the scalp condition.
