A good shampoo is an important feature to maintaining healthy hair, and there are many hair care shampoo options available to men and women. Some shampoos are general products used for ridding hair of dirt while other products have moisturizers, fortifying agents, and ingredients to combat dandruff. The Online Drugstore has many types available from leading hair shampoo brands including Suave, VO5 and Herbal Essences. Although some people swear by shampooing their hair every day, many hair stylists believe that washing your hair three or four times per week is sufficient. Many dermatologists also agree that shampooing daily is not necessary. Some believe that hair can become damaged if washed every day, even with the best shampoos for hair. If you have long, thick or curly hair, you can go longer between washes because oils from the scalp do not travel down the hair shaft as fast as seen on short hair. As a result, longer hair is usually drier, requiring less frequent shampooing. Of course, there are no hard and fast rules when it comes to shampooing your hair, so if you insist on washing your hair every day, by all means do so, just use a lighter-weight shampoo.
