Hairstylists face a common challenge with their clients every single day. Most of the clients experience hard water. How does this affect us? The truth is, what is hiding in your water, hiding in your clients hair. Minerals such as copper, iron and magnesium can wreak havoc on the hair. Without knowing about these issues, you could do more harm than good with the services you perform. The moral of the story is prep before you paid. Use Crystal Gel to remove obstacles from the hair to achieve more predictable results.
