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 is designed to help improve the health and condition of your hair. It typically contains a combination of natural ingredients such as oils, vitamins, and proteins that are intended to nourish and strengthen your hair. Hair serum can be applied directly to your hair or mixed with other products like shampoo and conditioner.
