Yes; you will find better performance, higher quality ingredients, higher concentration of the product (less water) and a better price per ounce or usage with the professional products. We find that most drug store brands "coat" the hair with a buildup that really affects your drying time! And eventually, will even prevent needed moisture absorption to your hair. Most professional products are formulated for targeted specific hair needs, so they really do need professional recommendation. You may buy something in the stores that will not work well with your hair, even if it is being sold as a "professional" product.
