You should be. It is great to rid your hair of excess oils. It will make your hair look and feel fresh again. I use it several times a week and it helps extend my blowout and my color. If you over shampoo your hair it can damage your hair and if you color your hair it will quickly fade.
There are several choices on the market. I prefer an aerosol spray. I found a great product at Sally Beauty. It is Beyond the Zone Rock On Dry Shampoo, here is the link Rock On Dry Shampoo.
Now to my delight, Sally Beauty is offering two more choices in the Beyond the Zone line. Dry Shampoo For Light Hair and Dry Shampoo For Medium-Dark Hair.
