For extension-worn hair.

Your ends never meet your scalp. Everything they get, you give them.

The hair at your ends is the oldest hair you own and it gets nothing from your scalp. Nera³ is four steps built to put back what that hair never receives.

Scalp oil travels down a hair shaft. It has never once traveled down an extension.

So the hair people see most is the hair getting the least. That isn’t a flaw in the install. It’s a gap in the routine around it.

Mid-lengths and ends.

Most of this ritual belongs where your own scalp can’t reach. Start below the attachment points and work down. The richer steps stay on the mid-lengths and ends, where the hair is oldest and driest.

The daily leave-in is the one that earns its place every morning. It’s weightless, which is the whole point of it. Anything heavy near the roots is a problem you’ll feel within a week.

Weightless, and not protein alone.

Three proteins of different molecular sizes reach different depths of the cuticle, alongside a bond-repair complex working on the hydrogen and ionic bonds inside the cortex. Moisture goes in with them, never after.

Protein on its own leaves hair stiff, and stiff hair at the ends is how tangling starts. The formulas work together, following the science. Not a single product doing everything.

What we don’t claim

We’re not going to tell you this is safe for your attachment type. We don’t know what’s holding your hair on, and anyone who tells you otherwise without asking isn’t being careful with something you paid for.

Your stylist knows. Ask her before you change anything, the way you would before a color service.

We’ll tell you what’s in it, where to put it and what it’s for. The rest is a conversation with the person who did your hair.

Care notes

Can I use this with tape-ins, wefts or bonds?

What’s in it is on every bottle and the full list is on each product page. Whether it suits your attachment type is your stylist’s call, and she’s the right person to ask before you change your routine.

Where do I put the treatment?

Mid-lengths and ends, below the attachment points. That’s where the oldest, driest hair is.

How often do I use the Protein Treatment?

Not every day. It’s a targeted step, not a daily one. How often depends on how much repair your hair is asking for.

Will it weigh my hair down?

The daily leave-in is built to be worn every day without weight. It’s the step we’d expect you to use most.

You chose the hair. Choose what goes on it.
