Photoprotective Effects of a Multifunctional Hair Care Formulation Containing Botanical Extracts, Vitamins, and UV Filters

The aim of this study was to develop and evaluate the efficacy of a multifunctional hair care formulation-Hair BB Cream-containing botanical extracts of Camellia sinensis, Vitis vinifera, and Euterpe orleacea, vitamins, amino acids, UV filters, and silicones for hair treatment and prevention of UV damages. The in vitro antioxidant activity of the botanical extracts was evaluated using the DPPH and chemiluminescence methods. A tensile test, combability, shine, and image analysis were performed to evaluate the efficacy of the formulation. To evaluate protection against UV damage, the hair strands were submitted to UV radiation without and with the application of the Hair BB Cream. The results showed that the application of the Hair BB Cream promoted a reduction in combability values and an increase in break stress and gloss values. After exposure to UV radiation, the hair treated with the BB Cream formulation showed no difference in the mechanical properties test, indicating protection against UV damage. In conclusion, the multifunctional formulation showed several benefits of single product acting in the prevention of UV damage and the treatment of hair damage. Thus, the Hair BB Cream proposed can be suggested as an effective multifunctional hair care product. (AU)
