It’s easy to feel overwhelmed by all the types of shampoo available today. They all seem to be “new and improved” and offer benefits that you aren’t even sure you need. This type of advertising has led to some misconceptions among consumers about what shampoo is supposed to do. Modern shampoos may claim to have countless benefits, everything from fattening hair strands to adding color to repairing damage. However, the primary requirement of shampoo has never changed; it has to clean the scalp and hair without causing dryness, damage, or irritation. It should also work well with all types of water.
