Abstract

The present disclosure relates to heat-treated Limosilactobacillus fermentum LM1020 for preventing hair loss and promoting hair growth, and more particularly, to heat-treated Limosilactobacillus fermentum LM1020 for preventing hair loss and promoting hair growth by promoting the proliferation of dermal papilla cells and a composition containing the same. Heat-treated Limosilactobacillus fermentum LM1020 of the present disclosure and a composition containing the same promotes the proliferation of dermal papilla cells, has excellent 5α-reductase-1 inhibitory activity, and promotes the expression of FGF7, FGF10, and EGF, which are growth factors, and thus have the effect of effect of preventing hair loss and promoting hair growth. The subject cell line referred to as Lactobacillus fermentum LM1020 has the International Depositary Authority accession number KCCM12918P, having been deposited on Dec. 23, 2020.

Claims (22)

1 . A cosmetic composition for proliferating dermal papilla cells, comprising:

heat-treated Limosilactobacillus fermentum LM1020 deposited under accession number KCCM12918P as an active ingredient.

2 . The cosmetic composition for proliferating dermal papilla cells of claim 1 , wherein the heat-treated Limosilactobacillus fermentum LM1020 is derived from fermented dough.

3 . The cosmetic composition for proliferating dermal papilla cells of claim 1 , wherein the heat-treated Limosilactobacillus fermentum LM1020 has a ratio of saturated fatty acids:unsaturated fatty acids:cyclic fatty acids of 0.1 to 2:0.25 to 5:0.03 to 0.6.

4 . The cosmetic composition for proliferating dermal papilla cells of claim 1 , wherein the heat-treated Limosilactobacillus fermentum LM1020 increases the expression of CDK2, CDK4, cyclin B1, and cyclin D1.

5 . The cosmetic composition for proliferating dermal papilla cells of claim 1 , wherein the heat-treated Limosilactobacillus fermentum LM1020 reduces a gene expression level of 5α-reductase-1 and increases gene expression levels of FGF7, FGF10, and EGF.

6 . The cosmetic composition for proliferating dermal papilla cells of claim 1 , further comprising:
