Definitely not every week!
Clarifying shampoo’s are designed to really
really clean the hair, which is a good thing, but not a good thing too often. I would recommend using a clarifying shampoo when your hair feels weighed down from tons of product, the shampoo will rid the extra gunk.
A lot of times our hair seems to stop responding to our favorite products not because our hair just decided not to like it anymore, but the majority of the time its because our hair is weighed down with moisturizer, oil, bits of conditioner, & residue.
So the use of a clarifying shampoo is definitely beneficial on average once a month, but it depends on your hair & the amount of product that’s sitting on top of it.
