Abstract: Hair is considered to be a major component of an individuals general appearance. It is also psychosocial important and patients both men and women with hair loss (alopecia) often deeply suffer. Demand for medications that alter hair growth and appearance has led to a multibillion-dollar industry and thus far few natural effective products are available. For the purpose of ascertaining natural products which possess hair growing activity we looked over onto ethanolic and aqueous extracts of E. cottonii. Hair follicle epithelial stem cells and their contribution to skin healing have attracted particular attention. Oral treatments commenced soon after shaving the dorsal interscapular area of healthy male Sprague-Dawley rats. Microscopic observations of skin were performed. This study showed ethanolic extract of E. cottonii enhanced hair growth by higher proliferative activity. Ethanolic extract of this seaweed increased the rate of wound contraction and epithelization when compared to positive and negative control groups. The ethanolic extract of E. cottonii was approximately 20% more effective than aqueous extraction. The extraction also possesses several antioxidant compounds which may be responsible for the accelerated hair growth and wound healing. We demonstrated for the first time in the present study that this seaweed extracts revealed faster healing and hair growth even when compared with positive control group.
