To get best results with System 1 Shampoo:

 

  1. Wet hair and scalp thoroughly.
  2. Apply a sufficient amount of shampoo to your scalp; massage gently, especially at the roots, for about 1 minute to allow the active ingredients to work and help lift buildup. 
  3. Rinse thoroughly.
  4. After shampooing, follow with the matching System 1 Conditioner. Using the full three‑step System 1 (shampoo + conditioner + leave‑in) is recommended for visible results. 
  5. Frequency: Use it regularly—often every time you wash; brand suggests using the full system at least 3 times a week for visible improvement.
