Sunscreen is the holy grail when it comes to protecting the skin from sun damage and harmful UV rays. Hair is as delicate as the skin and is prone to damage almost every single day. It eventually leads to serious damage in the form of limp, lifeless hair and split-ends. Therefore, the hair also requires protection from the external environment, especially from the sun. The harsh UV rays take away the #proteins and building factors of the hair. Applying hair sunscreen is the best way to protect it from sun damage and heat.
