The present invention relates to a cosmetic composition for preventing hair loss comprising riboflavin and angelica leaf extract as active ingredients.

Riboflavin (7,8-dimethyl-10-(D-ribo-2,3,4,5-tetrahydroxypentyl)isoalloxazine; 7,8-dimethyl-10-ribitylisoalloxazine) is a type of water-soluble vitamin known as vitamin B2. Also called lactoflavin. The molecular formula is C17H20N4O6, the molecular weight is 376.36, and it has the property of being decomposed at 278-282 °C and has the structure of Formula 1 below. Flavin means yellow in Latin, and the aqueous solution is actually yellow, and the anhydrous riboflavin powder has an orange color. Riboflavin is known to be involved in metabolism related to oxidation of carbohydrates and amino acids. It is abundantly present in milk, eggs, and liver of animals. Adults require 1.2 to 1.7 mg of vitamin B2 daily. A significant amount of vitamin B2 is also synthesized by bacteria in the large intestine. Therefore, the hair composition for preventing hair loss of the present invention containing riboflavin having such various functions not only increases the activation of dermal papilla cells but also increases blood circulation, thereby providing an excellent effect in preventing hair loss.

In the present invention, riboflavin was used by SIGMA's RIBOFLAVIN (EC No. 201-507-1). Riboflavin has the structure of Formula 1 below.

The riboflavin is characterized in that it is contained in an amount of 0.00001 to 0.006% by weight based on the total weight of the cosmetic composition. If the content of the extract is less than 0.0001% by weight, the effect of preventing hair loss does not appear, and when it exceeds 0.006% by weight, the degree of increase in the effect of preventing hair loss with respect to the increase in the content is insignificant, and there is a problem in safety and stability in the formulation and economy. not even an enemy

[Experimental Example 1]

Human-derived dermal papilla cells are cultured using DMEM medium containing 10% FBS and 1% antibiotics (100 units/ml penicillin and 100 ug/ml streptomycin). The effect of growth and proliferation of dermal papilla cells was confirmed by MTT assay using 3rd and 4th generation dermal papilla cells. In a 96-well microplate, dermal papilla cells (1×104 cells/ml) were put in DMEM medium containing 1% FBS, and pre-cultured for 24 hours, and the samples obtained from Preparation Example were treated with various concentrations, and then cultured for 4 days. 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) ) was added and incubated for another 4 hours, and then centrifuged to remove the supernatant. After dissolving the precipitate by adding dimethyl sulfoxide to it, the proliferation effect of human-derived dermal papilla cells was confirmed to the extent of the formation of the formazan precipitate according to the reduction of MTT, and the results are shown in Table 1.

In the case of hair growth, if there is hair growth on the entire head and there is an increase in the number of hairs, it is 'Very good', if there is hair growth on a part of the head and there is an increase in the number of hair in a part of the head, it is 'good', if there is no symptom of hair growth In the case of hair nutritional status, it was set as 'Very good' if there was little damage to the hair and if the hair was in a smooth and abundant condition, 'Good' if the hair damage was limited to a part and the hair was smooth. If there was no improvement in hair condition, it was set as 'no change'. In the case of scalp condition, if the scalp is completely free of sebum and there is no itching, if the scalp is clean, it is 'Very good', if the sebum or itching is partially improved and the cleanliness is improved. 'Good', and 'No change' if there was no change in scalp condition before use.

As can be seen in Table 3 above, when the composition for preventing hair loss containing riboflavin was continuously used, the effect of reducing the hair loss rate was shown to 55% or more of users, and the effect of preventing hair loss was shown to all users as well. , had the effect of thickening fine hair or fine hair. In addition, it was confirmed that most of the hair nutritional status had a good change, and the effect was excellent by more than 65%, and the condition of the scalp was mostly improved.
