Description

Composition for hair growth stimulation or hair loss prevention using halla chive extract {Composition for Hair Growth Stimulation or Hair Loss Prevention Using an Extract of Allium taquetii}

The present invention relates to a composition for promoting hair growth or inhibiting hair loss using Allium taquetii extract.

Hair is formed from hair follicles. There are about 5 million hair follicles in an adult, which are distributed throughout the entire human skin except for the palms and sea gourds. There are 1 million in the head, and 100,000 of these are in the scalp. (Bulletin of Food Technology 2009, 22(4):651-663). Scalp hair accounts for about 20% of human hair, and has the function of protecting the head from shock by cushioning the head in addition to the physiological functions of hair such as evaporation of sweat and regulating body temperature, and is suitable for modern people's tendency to value appearance. It also has an important social function in creating an individual's personality and image (Clin Dermatol 2001, 19(2):161-166).

Each hair grows from a hair follicle, and the hair follicle is composed of dermal papilla cells, hair germinal matrix cells, an outer and inner layer, and a bulge. do. In particular, hair follicle dermal papilla cell (hDPC) is a cell located in the dermal papillae at the bottom of the hair follicle and regulates the development and growth of the hair follicle (J Cell Sci 2011; 124(8): 1179-1182).

Hair repeats the growth cycle of anagen, catagen, and telogen. During the anagen phase, hair dermal papilla cells and human hair germinal matrix cells develop, This is the period when keratinocytes keratinize and hair grows. The catagen phase is the period when cell division stops, hair growth stops and the shape of the hair is maintained, and the telogen phase is when hair cells begin to become active and new hair is generated. This is the time to shed old hair.

Therefore, factors that affect the proliferation of dermal papilla cells or hair follicle cells in hair development, growth, and shedding are important targets for improving hair loss or hair growth.

Meanwhile, alopecia refers to the turning of terminal hair into vellus hair or the loss of hair that should normally exist. Usually, about 50 to 100 hairs fall out per day, but if there are more than 100 hairs, it is highly likely that it is alopecia. Alopecia is divided into cicatricial alopecia, which is permanent hair loss in which the hair follicles are damaged and hair does not regenerate, and non-scarring alopecia, which is treatable because the hair follicles are maintained (Bong-Hyeon Joo et al., 2014). As the average human lifespan increases, alopecia is considered a disease rather than a force majeure, and alopecia prevention and hair growth are receiving attention from many people (Ann N Y Acad Sci. 1991. 26(642):11).

The exact mechanism of hair growth and hair loss is not completely known to date, but the causes of hair loss include a decrease in hair follicle function due to the involvement of male hormones, a decrease in the metabolic function of the hair follicle and hair bulb, local blood flow disturbance due to scalp tension, poor nutrition, It is very diverse, including stress, side effects from medications, genetic factors, autoimmunity, local infections, chemicals, diseases such as leukemia and tuberculosis, and abuse of hair products.

Currently, the most commonly used drugs for hair loss treatment are substances that inhibit the activity of type 2 5α-reductase, including Minoxidil (see U.S. Patent Nos. 4,139,619 and 4,596,812) and finasteride (U.S. Patent Nos. Examples include No. 5547957, No. 5760046 or Republic of Korea Patent No. 375083.

Hair loss treatment requires long-term treatment, so minimizing side effects is key. Accordingly, efforts are being made to discover new hair growth ingredients or materials from natural products that have relatively few side effects on the human body.

Accordingly, the present invention discloses the hair loss inhibition activity of Halla chive extract.

The purpose of the present invention is to provide a composition for promoting hair growth or inhibiting hair loss using Halla chive extract.
