The present invention relates to a composition for preventing hair loss and promoting hair growth, and more specifically, to an agent for preventing hair loss and promoting hair growth, comprising various effective components contained in the extracts extracted from natural plants as active ingredients for inhibiting hair loss and promoting hair growth, wherein the natural plants comprise Fructus Vtticis, Radix Sophorae flavescentis, Cacumen Biotae, Ecliptae herba, Polyporus, Fructus Arcth, Psoraleae semen, Carthami flos, Boraginaceae, Rosa multiflora, Umbelliferae, Acorus gramineus Solander, Umbelliferae, rosin, and Rutaceae. More specifically, the present invention provides an agent for preventing hair loss and promoting hair growth, comprising a variety of substances, such as acetosyringone which inhibits dihydrotestosterone formation by inhibiting 5α-reductase formation and promotes the production of IGF-(insulin-like growth factor-1) and keratinocyte growth factor (KGF), thereby promoting hair growth; and sterol, flavonoid compounds, and flavonoid-based compounds which inhibit activities of 3,4-di-hydoxbenzaldehyde, polryporusterone A, and cGMP phospo-diesterase type 5 (PDE5). In addition, the agent for preventing hair loss and promoting hair growth uses a tree sap as a substance causing the effective substances to be absorbed into the scalp.COPYRIGHT KIPO 2020본 발명은 탈모방지 및 발모제 조성물에 관한 것으로,천연 식물들인 만형자, 고삼, 측백, 한련초, 저령과 그리고 우방자, 보골지, 홍화, 자초, 영실, 천궁, 석창포 백지, 송지, 산초로부터 추출한 추출물에 포함된 다양한 유효성분을 탈모저해 및 발모촉진 활성물질로 포함하는 탈모방지 및 발모제를 제공한다.상세하게는 5α-reductase의 생성을 억제시켜 dihydrotestosterone생성을 저지하며, 성장호르몬 IGF-(insulin-like growth factor-1) 및 KGF(keratinocyte growth factor)의 생성을 촉진시키어, 발모 작용을 할 수 있는 asetosyringone. 3.4-di-hydoxbenzaldehyde 및 polryporusterone A와 cGMP phospo-diesterase type 5 (PDE5)의 활성을 억제하는 , Sterol, Flavonoid화합물 및 Flavonoid계열 화합물 등 다양한 물질이 포함된 탈모방지제 및 발모제의 제공이며,또한 상기 유효물질를 두피에 흡수시키는 물질를 나무수액을 이용하는 특징을 갖는 탈모방지제 및 발모제를 제공한다.[ 색인어 ]저령, 만형자, 우방자. a
