Hair Extensions & Keratin: The nighttime mistake ruining your investment

You spend hundreds of euros at the salon for premium extensions, a Brazilian blowout, or a keratin treatment. But after just a few weeks, the bonds start to slip, the keratin wears off, and tangles form at the roots. The main culprit isn't your shampoo—it's the friction from your cotton pillowcase while you sleep.

The Mechanical Stress on Hair Bonds

Cotton is a highly abrasive material. When you sleep, the rough fibers grab onto the micro-bonds of your extensions or strip the delicate keratin coating from your hair shaft. This 8-hour nightly tug-of-war weakens the adhesive, causes severe matting at the roots, and drastically reduces the lifespan of your salon treatments.

Absolute Smoothness is Mandatory

To truly protect expensive hair treatments, the surface you sleep on must have zero catch points. This is why the Silkhouse pillowcase is designed strictly without embroidery, raised logos, or useless decorative seams. Any textured detail can catch a fragile hair bond. We deliver a sober, simple, and flawlessly smooth silk surface. Pro tip: If you wear eyelash extensions too, complement your frictionless sleep with our 3D zero-pressure silk sleep mask to protect your lashes.
