A Study on the Protective Efficacy and Cell Proliferation of Dermal Papilla Cells by Spirulina Extract

The study investigates the effects of spirulina extract on dermal papilla cells, which are crucial for hair growth and cycle regulation. The research found that spirulina extract, containing 26.66 μg/ml of phycocyanin, acts as an antioxidant, reducing reactive oxygen species (ROS) in cells exposed to UVA. It also enhances cell proliferation, particularly at a concentration of 0.10 mg/ml, as evidenced by increased cell proliferation 24 hours post-treatment. These findings suggest that spirulina extract could be beneficial in developing products for scalp protection and hair loss improvement.
