Splurge or Save on Shampoo?
Shampoos are designed to cleanse the hair, and any fancy ingredients will probably go down the drain with the suds. If you have normal, non-chemically treated hair, most drugstore shampoos will do the trick. If you love the feel or the scent of an expensive shampoo but worry about the cost, rotate in a less expensive brand every other day or once a week, depending on how often you wash your hair. Recommended product: Garnier Fructis Fortifying Shampoo ($4 at drugstores and amazon.com) is touted by hairstylists as a great inexpensive shampoo.
If you have spent a small fortune coloring or highlighting your hair, you might want to go with the product that your hairstylist recommends to best preserve your color.
