you joke but that's basically true, at least for some people.

I stopped using shampoo outside of special occasions and after like a month of my scalp vomiting grease it realized i wasn't constantly removing it and calmed down. Now my hair just constantly looks like i shampooed it a day ago, and it takes only the tiniest amount of shampoo to be effective.

I recommend just trying ramping down your shampoo usage gradually to nothing, and waiting as long as you can tolerate to see if your scalp stops overcompensating, and then only using as much shampoo as is actually needed for you to be satisfied.

Not only is it way nicer, it's gonna save you a bunch of money too.
