Blue shampoo that I use to extend time between hair appointments! I used to think I was supposed to use purple shampoo to prevent the blonde in my hair from turning gold but appaaaarently, as a brunette, I should’ve been using blue this entire time. This one works great for me and is under $10! 👱‍♀️ Depending on how often I’m washing my hair, I usually use once every week to week and a half. And I’ll use a hair mask/deep conditioner right after each use. LTKunder20, hair, hair products LTKbeauty LTKstyletip
