When I start building a formula, I often ask a simple question: What is the hair follicle trying to tell me?
Not what I want it to do, but what it is already doing, or failing to do, because when you start looking at hair through that lens, everything changes.
It stops being a strand you condition and becomes a system you listen to.
In cosmetic science, we are trained to think in ingredients: oils, polymers, actives.
But the scalp does not understand ingredients, the scalp understands signals.
