The present invention relates to a composition for improving or promoting hair growth, which contains, as an active ingredient, a photosensitizer-peptide conjugate, and to a method for screening for the hair growth promoter using the active ingredients. ALA, which is the photosensitizer of the present invention, is preferably activated by LED radiation, and more preferably activated by radiation having a long wavelength of 650 to 675 nm. The peptide of the present invention is a peptide in which 3 to 7 amino acid residues are incorporated (most preferably, glycine-histidine-lysine), and may cooperate with the photosensitizer to enable very superior hair growth improving or promoting effects using light radiation. Further, the composition of the present invention may exhibit further superior effects when natural extracts (for example,
Cimicifuga heracleifolia
extracts,
Scutellaria baicalensis
extracts or
Codonopsis lanceolata
extracts) are added. Thus, the composition of the present invention can be significantly advantageously applied to drugs, quasi-drugs, and cosmetics.
本发明涉及一种用于改善或促进头发生长的组合物,其包含作为活性成分的光敏剂-肽共轭物,并且涉及使用该活性成分筛选促进头发生长的方法。本发明的光敏剂A
LA最好由LED辐射激活,更好地由长波长为650到675纳米的辐射激活。本发明的肽是一种包含3到7个
氨基酸残基的肽(最好是甘
氨酸-组
氨酸-赖
氨酸),并且可以与光敏剂协同作用,使用光辐射实现非常优越的头发生长改善或促进效果。此外,当添加天然
提取物(例如,升麻
提取物、黄芩
提取物或刺参
提取物)时,本发明的组合物可能表现出更优越的效果。因此,本发明的组合物可以显著地优势应用于药物、准药物和化妆品。
