I've been hearing a lot of buzz about a new type of hair care product called "hair serum." What is it, and is it safe to use?

Hair serum is a type of hair care product that contains natural ingredients designed to nourish and strengthen hair. It's typically applied after shampooing and before styling, and can help improve the overall health and texture of your hair. Hair serums are generally considered safe when used as directed, but you should always consult with a professional stylist before using any hair products for optimal results.
