Serum or cream — which for which hairSerum or cream — which for which hair

Fine or oily hair: start with the serum. C12 is weightless, never heavy, and gives shine without film. The cream comes later, when you want deep repair on the lengths.

Dry, bleached or coloured hair: start with the cream. CX rebuilds the cortex from within and restores elasticity where chemistry took the structure. The serum is then daily shine and protection.

If you can have both — take the box. Serum opens, cream builds, comb seals: together they cost less than the sum of the parts and do what none does alone. The box isn't a bundle, it's the whole ritual.
