The mechanism of hair growth has been clarifying itself by the improvement in the culture techniques for hair follicle cells. Recently stem cells inducing the anagen phase in the hair follicle cycle have been discovered in the bulge region of the outer root sheath (ORS). To find growth‐promoting agents for the ORS cells, we evaluated the effect of various botanical extracts on the growth of cultured human hair follicles. We found that Laminaria angustata extract increased the ORS cell growth. Further, hair‐growth in the shaved skin of C3H mice was also promoted by the topical application of the extract.
