I let this sit in my hair for 30 minutes once a week before I wash my hair.
When I’m feeling indulgent
If you have a dry scalp or dry hair, definitely only use every other week. However, I LOVE how clean this gets my hair, especially living in a big city with pollution and hard water.
This is one of my favorite drugstore shampoos! I always go back to it even after trying many higher end brands.
