Do you need a new hairstyle? You do need to know some basics of hair care before getting started with long hairstyles though. First, shampooing long hair is best done standing up, preferably in the shower. This helps reduce matting and tangling. You should choose a shampoo that fits your hair's needs. For instance, chemically treated or damaged hair should be treated with a moisturizing shampoo and conditioner. Use several towels to blot your hair dry. Never rub wet hair because this is a major cause of matting and tangling.
