Hair protection refers to practices and products designed to shield hair from damage caused by environmental factors, heat styling, and chemical treatments. Common protective measures include using heat protectant sprays before styling, wearing hats in harsh weather, and applying leave-in conditioners to maintain moisture and prevent breakage. Additionally, protective hairstyles, such as braids or buns, can help minimize hair manipulation and reduce stress on the strands. Regular trims and using sulfate-free shampoos can also contribute to healthier hair by preventing split ends and maintaining natural oils.
