A Letter from the Founder

I created SIVÈL because I know what it feels like to sit behind the chair and be responsible for results you didn’t have full control over.

I’ve worn extensions. I’ve installed them on real clients. I’ve dealt with fading pigment, green undertones, dryness, broken promises, unpredictable shipping, and brands that stop supporting you the moment the sale is made.

That didn’t sit right with me.

SIVÈL was built differently — intentionally — by a stylist who believes hair extensions are not just a product, but a responsibility. A responsibility to clients who trust us with their confidence, and to stylists who deserve honesty, education, and real support.

There is no gatekeeping here.
No shortcuts.
No selling without teaching.

My goal isn’t just to give you beautiful hair — it’s to give you clarity, confidence, and the tools to build something sustainable behind the chair.

If you’re here, you value integrity over hype and education over trends.
That’s exactly who SIVÈL was created for.
