Histological features of the skin specimen of different extract and/or vehicle control treated mice. Macroscopic observation of hair in the skin surface of (A) control, (B) minoxidil, (C) A. radix, (D) E. alba, and (E) P. ginseng in early hair existing phase. Microscopic observation of longitudinal sections of (A′) control, (B′) minoxidil, (C′) A. radix, (D′) E. alba, and (E′) P. ginseng treated mice skin was harvested and fixed in buffered formalin for routine hematoxylin and eosin (H&E) stained histology (). The broken line indicates defective HFs at the level of sebaceous gland ((A′), (B′), (C′), and (E′)). Note that the straight hair shafts that emerge from the skin surface of minoxidil and E. alba treated mouse ((B), (D) and Arrows (B′), (D′)). Scale bar 100 μm.
