Details

Rinse-free serum with keratin, for fragile, dry or damaged hair. It works mostly on the surface of the fiber: it forms a very thin film that helps control frizz and adds shine. That is the difference with the leave-in, which hydrates and protects, while the serum takes care of the finish. It goes at the end of the routine, after the leave-in. 100 ml format.

Serum or leave-in?

They do different things and can be used together. The leave-in hydrates and protects from heat; the serum forms a thin film on the surface of the fiber and takes care of the finish, the shine and the frizz. The order is leave-in first, serum after.

On damp or dry hair?

Both work and the result changes. On damp hair it spreads more easily and comes out more even. On dry hair the frizz control shows more, because it acts right where you see it.

How much do I use?

Start with less than you think, just a few drops. Adding is easy; removing the excess means washing again. And never at the roots, which weighs the hair down and makes it greasy sooner.

Can I combine it with the rest of the range?

Yes, and the order matters. First what gets rinsed out: shampoo and then conditioner or mask, never both on the same day because they do the same job. Then what stays in: first the leave-in, which hydrates and protects from heat, and on top the serum, which seals and takes care of the finish. The vials work internally, so they do not interfere with anything you apply.

How long does it take to show?

It depends on what the product acts on, and it is worth separating the two. What works on the shaft, that is the visible part of the hair, shows from the first use, because the shaft is already formed tissue and what changes is its surface. What depends on the follicle goes at the pace of the hair cycle: hair grows on the order of a centimeter a month, so any change in new hair takes months to appear. That is why the vial routines are planned by seasons and not by weeks.

Can I mix it with products from other brands?

Yes. What is worth watching is not the brand, but not repeating two products with the same function: two conditioners, or a conditioner and a mask on the same day, overlap. If you already use several products with proteins, go slowly before adding one more.

Where can I buy it?

At the stores. This site does not sell: it is a catalog with the range and its information, and the purchase is made in the store, where there is also someone who can advise you. The Where to buy page has the list with addresses and opening hours.
