Should I change my shampoo on a regular basis?

Most of us have heard, at one time or another, that the best way to have healthy, shiny and vibrant hair is to change shampoos on a regular basis. But what if you’ve finally found your dream shampoo and really don’t feel like changing? Dream shampoo or not, when you wash your hair everyday, or at least on a regular basis (most of us do!) your shampoo will build up on your hair shaft, as will conditioner and styling products.
This isn’t to say that your products are lacking in quality—even the best products applied on a regular basis will create build-up on your hair. Changing shampoos doesn’t actually get rid of this build-up, but as each shampoo’s ingredients differ, changing products will give it a “new” wash.
If you really don’t want to part with your beloved shampoo, try a natural alternative. A few times a month, apply a vinegar rinse to your hair. This is a gentle and natural way to strip your hair of product build-up and reset your hair’s PH balance, which will result in shinier locks. Cider vinegar is the best variety to use: add one teaspoon to a cup of lukewarm water and rinse your hair with the concoction after shampooing. You can then either rinse out the vinegar rinse with warm (not hot) water, or leave it in. Although vinegar smells strong when applied, fear not, the smell disappears as your hair dries.
For those of you who like tinkering in the kitchen to create your own hair-care products, certain herbs can be added to the vinegar rinse to enhance a particular color. More on that in an upcoming post!
