What is a one-sentence summary of the following article?
Shampoos are made to cater to hair types. You may come across some brands on the shelf that declare right on the face of the bottle that the product will reduce frizzy hair. Otherwise, look for the words "moisturizing," "smoothing" or "hydrating" on the bottle of your favorite brand. Normal or leave-in — it all depends on what's in the conditioner. When searching for a conditioner, look for conditioners that have one or both of the following ingredients: amino silicones and cationic surfactants. These two ingredients help fight the two main causes of puffiness: damage in the hair shaft and static electricity.  Amino silicones help the silicones in conditioner to grab onto damaged hair shafts, providing more lasting conditioning. Cationic surfactants help cut down on puffiness causes by static electricity by carrying a positive charge. Smoothing serums coat the hair shaft, helping to reduce frizz much like conditioners will. Some of these products, however, are heavy and can weigh your hair down too much. Use sparingly until you discover the right amount of the product to use for your hair.
Choose a shampoo designed to fight frizz or puffiness. Choose the right kind of conditioner. Use a smoothing hair product.
