Everyday Cheapskate: The Costly Mistakes You Make with Your Choice of Shampoo
Fact: The only part of the shampoo bottle that's regulated by the Food and Drug Administration (FDA) is the list of ingredients. Manufacturers can make any claim they like on the unregulated portions of the label. Sometimes the hype has some merit. Often it has none. Manufacturers can make just about any claim they can think up!
Myth: Shampoo builds up on hair, so you need to change brands occasionally to counteract.
Shampoo cannot build up on hair. However, conditioners, chemical processes and other products do build up, so you may need to use a stronger type of shampoo from time to time. Or do this once a month: Mix a little baking soda with your shampoo in the palm of your hand. Shampoo as usual, and rinse well. There you go. No need for an expensive "rid" product to wash buildup away.
Myth: Salon-brand shampoos outperform inexpensive store brands.
Not true. Salon brands may have more fragrance, foam more or have more ingredients, but all of it goes right down the drain with the detergent.
REPAIR AND NOURISH
Myth: High-quality shampoo can repair and nourish damaged hair.
