Decent, just nothing special

I used this for a while, I’ve tried a fair share of clarifying shampoos and this one is alright. Nothing fancy and tends to dry my scalp out. I alternate shampoos to avoid dryness. It does clean the scalp well but it’s just drying and doesn’t leave much moister.

I love the K18 detox shampoo, a little does a long way, I use this 1x a week and it helps my hair be less oily and heavy. I tried to not like it because the price is a bit much but I think it's worth it after using it for a few months I can tell a difference when you pair it with the leave-in conditioner
