How will I know when I found the right staple product for my hair
Either your hair will look exactly the way you want it to, or the way I tell is I ask myself if I want to continue searching. For example, I use devacurl low poo for my cleanser, and when I hear or read people talking about another cleanser they like, I ask myself if I should try it, and the answer is always "no, I love the way my hair looks and feels when I use the low poo, so I don't wanna mess around with my routine". You want a product that you have no interest in changing, and if you do, keep looking and continue to ask yourself if you want to keep messing around.
I like Jessi's answer!If I'm liking the way my hair is lookin', I stick with it. Sometimes I'll like my hair with a certain product for a few months, then all of a sudden... ick! And I have to change products again.
Sometimes you never do!
