Bought larger bottle, shampoo seems thinner?

I have been using this shampoo for about 6 months now and really like how my hair looks and feels. I recently decided to order the larger bottle but noticed when I started using it that it seems watered down. I have to use more shampoo than I did with the smaller bottle which is upsetting. Now I am questioning the quality of your product and the ethics of your company. Please do better.

Just okay

The shampoo smells amazing but it made my hair dry and frizzy (more so than it typically is).
