  • Patent number: 11771636
    Abstract: The present invention relates to a composition comprising adiponectin-derived peptide fragments and, more specifically, to a cosmetic composition and pharmaceutical composition for promoting hair growth comprising, as an active ingredient, one or more adiponectin-derived peptides selected from the group consisting of amino acid sequences of SEQ ID NOS: 1 to 21. The adiponectin-derived peptides activate the cell division of dermal papilla cells and outer root sheath cells of hair follicles, promote hair growth in the hair follicles, and also increase the expression of hair growth factors in the dermal papilla cells, and thus a composition of the present invention comprising the adiponectin-derived peptides can be effectively used to promote hair growth and inhibit hair loss.
