Oh my gosh I am in love with this stuff! I put it in my hair after my leave-in conditioner and my hair is super soft on top of being less frizzy. It is definitely a lot better than argan oil, which is what I've been using. (Say what you want, but argan oil is still oil, and made my hair kind of greasy.) This is the cashmere touch hydrating serum from TRESemmé nourishing rituals. You can get it for $8.66 on Amazon. (Or do what I did and borrow it from your little brother. Whatever works.)
