This invention relates to a cosmetic composition, which controls sebum secretion of the scalp to thus create an optimal environment for hair growth and activates growth factors for promoting hair strengthening and growth, thereby improving the health of the scalp. A method of preparing the same is also provided. In the cosmetic composition, an oligopeptide functions to create an environment suitable for hair growth by controlling the sebum secretion of the scalp, and also to activate growth factors that are effective at preventing hair loss by promoting hair growth through improvement of blood circulation in the scalp and by strengthening hair through hair follicle activity, thereby improving the health of the scalp and preventing hair loss. The oligopeptide of the invention can exhibit high safety and stability of use and high absorbability into the skin and is thus excellent in improving the health of the scalp, compared to the use of existing peptide compositions.
