Science

The Problem: Traditional shampoos contain harmful sulfates which clean your hair by stripping it. They also contain silicones and oils, which build up on hair, attracting dirt and oil, and weigh it down.

The Solution: PhD Shampoo is a revolutionary shampoo that is silicone and oil-free and is powered by our patented Healthy Hair Molecule (OFPMA), which creates a weightless shield around each hair strand that: 

  • repels dirt & oil allowing you to wash your hair less often
  • promotes stronger, healthier and more manageable hair 
  • provides instant results that get better over time
