Dryness of hair strands can be caused by genetics or environmental factors, and this issue can be significantly treated with the Srita protective two-phase serum, suitable for dry and damaged hair. Some reasons for hair strand dryness include improper washing (scrubbing), excessive washing of hair strands, rough drying (towel rubbing), improper combing, frequent hair coloring, overuse of chemicals (such as bleaching), excessive use of heat tools (flat irons and hair dryers), and not using the right protective products (hair masks and serums). This dryness can lead to severe damage to hair strands and ultimately cause frizz.
