Abstract

This study examines the role of six species of microalgae, including Phaeodacylum tricrnutum (PT), Chaetoceros gracilis (CG), Nanochloris oculata (NO), Pavlova lutheri (PL), Chlorella ellipsoidae (CE), and Scendedemus obliquus (SO), on hair loss prevention and scalp improvement. To determine the effects of microalgae extracts on hair loss prevention and scalp improvement, antioxidant activity, cell proliferation in HaCaT cells and HFDPC cells, and the inhibition level of 5-alpha reductase activity were examined. In the study of antioxidant activity, the $EC_{50}$ values of DPPH anti-radical activities indicated that the SO, CG, and ST9 treatment groups demonstrate significant antioxidant activity. In the study of the hydroxyl radical scavenging activity, CG (6.6~42.1%), ST9 (26.0~44.0%), and SO (7.8~44.3%) demonstrated significant effects. Furthermore, SO promoted the proliferation of HaCaT cells and a human epidermal cell line during a 6-day treatment. In the study of the proliferation of HFDPC cells, a hair follicle dermal papilla cell line, CG, and SO significantly stimulated cell proliferation. Finally, PT, CG, and SO significantly inhibited 5-alpha reductase activity. These results suggest that among the six microalgae used in this study, CG and SO have antioxidant effects, induce cell proliferation, inhibit 5-alpha reductase activity, and can be used for hair loss prevention and scalp improvement.

이번 연구에서 우리는 6종의 미세조류 ; Phaeodacylum tricrnutum (PT), Chaetoceros gracilis (CG), Nanochloris oculata (NO), Pavlova lutheri (PL), Chlorella ellipsoidae (CE), and Scendedemus obliquus (SO)를 이용하여 탈모 예방 및 두피 개선효과를 살펴보았다. DPPH 라디칼 소거능 실험에서는 SO, CG, ST9 순으로 활성이 높은 것으로 나타났다. OH 소거능 실험 결과, CG (6.6~42.1%), ST9 (26.0~44.0%), SO (7.8~44.3%)으로 유의적인 효과를 보였다. 그외에도 세포증식실험에서는, SO가 인간표피세포주인 HaCaT 세포 증식을 촉진시켰으며, CG와 SO가 모유두세포주인 HFDPC 세포 증식을 촉진시키는 것으로 나타났다. 마지막으로 5-alpha reductase 저해능 실험결과, PT, CG, SO가 유의적으로 효소활성을 저해하였다. 따라서, 이번 연구에 사용한 6종의 미세조류들 중, 항산화활성, 세포증식 효과, 5-alpha reductase 저해능을 보인 몇가지 조류들이 탈모예방 및 두피개선을 위한 제품개발에 좋은 원료가 될 가능성이 있음을 제시한다.
