Dandruff shampoo is a scam!
I never had a dandruff problem, but I started using a dandruff shampoo for its alledged side effect of helping thinning hair.
Boom! 2 weeks in, granted my hair may be improving a little, but I now have some white flakes taking a peak out of my head here and there.
Or maybe this shampoo does help with dandruff for those with a problem, but just gives it to innocent dandruffless people like myself.
