The present invention relates to a colloidal composition for promoting hair growth and a manufacturing method thereof. The colloidal composition for promoting hair growth comprises a first mixture including 10 to 20 parts by weight of palm oil and 3 to 8 parts by weight of rice bran oil or soy oil 1 to 5 parts by weight of an additive, which is additionally mixed with the mixture, including 2-methyl-4-dimethylaminomethyl-5-hydroxybenzimidazol or a hydrochloride thereof as a main component a second mixture, which is mixed with the mixture and the additive, including 10 to 30 parts by weight of an organic solvent, 8 to 15 parts by weight of a saponifying agent, 5 to 15 parts by weight of a surfactant and 5 to 15 parts by weight of an emulsifying agent and 2 to 10 parts by weight of tocopherol mixed with the mixture, the additive and the additional mixture and stirred. Accordingly the present invention can manufacture a hair restorer and a hair loss preventing agent which are not harmful to a human body and are effective, because the present invention includes an additive and a natural material additive containing 2-methyl-4-dimethylaminomethyl-5-hydroxybenzimidazol or a hydrochloride thereof, which is effective in preventing hair loss and promoting hair growth, as a main component, thereby improving the effects of promoting hair growth and preventing hair loss compared with existing compositions.COPYRIGHT KIPO 2014[Reference numerals] (AA) Heat palm oil (BB) Add rice bran oil or soy oil (CC) Mix additive A (DD) Mix lecithin (EE) Add an organic solvent, a saponifying agent, a surfactant and an emulsifying agent (FF) High-speed stirring (GG) Colloidal composition (HH) Add tocopherol (II) Ultrahigh-speed stirring (JJ) Refine colloid (KK) Filtration (MM) Undiluted solution of a detergent composition본 발명은 모발생장촉진조성물 및 그 제조방법에 관한 것으로, 본 발명은 팜유 10~20중량부, 미강유 또는 대두유 3~8중량부를 포함하는 1차혼합물과, 상기 혼합물에 추가로 혼합되는 2-메틸-4-디메틸아미노메틸-5-하이드록시벤즈이미다졸 또는 그 염산염을 주성분으로 하는 1~5중량부의 첨가제와, 상기 혼합물 및 첨가
