Fermented Probiotics, Cationic Hyaluronic Acid, Niacinamide (Vitamin B3) and Panthenol (Vitamin B5) are layered together with gentle ingredients and natural oils to help soothe a dry, flakey, sensitive scalp, support follicle health, protect thinning hair while supporting collagen.
This purposely gentle formula delivers deep hydration to enhance manageability, restore shine and nourish ageing or environmentally damaged hair.
A conditioner that and adds shine, softness, and hydration.

CATALINA'S NOTA
Use root to tip
I designed this conditioner to nourish both ends and scalp. I love how it adds moisture if I am experiencing dryness or itchiness. Thanks to fermented probiotics, I also find it lets me stretch a little longer between wash days wash days, which is always a win.
CATALINA'S NOTA
Leave In!
Our shampoo and conditioner are designed to work in harmony - while the shampoo gently cleanses without stripping, the conditioner locks in hydration, supports the scalp barrier, and seals the cuticle for smoother, shinier strands.
