Description

A composition for hair protection containing brown mealworm larva oil as an active ingredient {COMPOSITION FOR PROTECTION OF HAIR COMPRISING TENEBRIO MOLITOR MEALWORM OIL AS ACTIVE INGREDIENT}

The present invention relates to a composition for hair protection containing brown mealworm larva oil as an active ingredient, and more particularly, to a hair protection composition containing brown mealworm larva oil as an active ingredient, which has a regenerating effect of damaged hair and a hair protection function. .

Although hair is not directly related to life, it has functions such as protection of the body, warmth and touch, and also acts as a cushion against friction from the outside, and protects the head from direct sunlight, cold and heat. plays a role In addition, eyebrows, eyelashes, nose hair, ear hair, etc. have a protective function against intrusion of sweat, dust, and insects. Hair not only protects the head, but also absorbs heavy metals such as mercury, arsenic and lead that are not needed by the body and discharges them out of the body. In addition, hair plays an important role in representing the characteristics of men and women in terms of decoration. Even the same person can give a different impression by changing the hairstyle and hair color. In this way, hair not only protects the head, but also plays a decorative role.

Hair is a thin and thin protein structure with an average thickness of about 0.07 mm, and can be broadly divided into a hair shaft outside the skin and a hair root inside the skin. The scalp has a basic structure and physiological function similar to that of the skin, and the hair follicle of the scalp is characterized by more complex and more sebaceous glands than other areas. The hair root is the part inside the hair follicle, which is buried in the scalp, and is about 2-4 mm deep. The bottom part of the hair root is swollen like a bead, and this part is called the hair bulb, and the thickness of the hair is determined by the size of this part.

If you enlarge the cross section of the hair, it is divided into three parts: the innermost part and the center, the medulla, the cortex surrounding the medulla, and the outermost part, the cuticle. The epidermis covers the surface of the hair and is a highly chemically resistant place that surrounds the inside of the hair. It is composed of three layers called epicuticle, exocuticle, and endocuticle from the outside. The cortex is located inside the epidermis and occupies most of the hair (85-90%). Its main component is keratin protein, and it is composed of cortical cells and intercellular binding materials. . The medulla is present in the center of the hair and contains some melanin pigment particles, and there are many large and small vacuoles in the medulla and contains air.

Modern people do a lot of damage to their hair by perming, drying, and dyeing, and frequent washing has become unavoidable due to the use of various hair dressings and air pollution. However, despite many efforts to restore the damaged hair to its original healthy state due to frequent chemical treatment and washing, the results have been few. This is because hair is a dead tissue unlike other living tissues, so there is a limit to revive the damaged area.

Therefore, there is an urgent need to prepare a new hair composition capable of effectively regenerating damaged hair, improving the hair protection function, and enhancing moisturizing power.
