Thicken It Studios, Inc.

The double-sided tape-in is the one moving fastest, which tracks — it's the method we built the company on.

Supported top and bottom by your own hair, so it lies flat and stays invisible where it attaches.

Marked down through December 31.

Dark hair is the hardest match and the one we get asked about most, because "black" is about nine different colours depending on the light.

Photograph in daylight. Match to the mid-lengths. Send it to us if you're between two.

Marked down through December 31, across the line.

Fashion Strips, in case you've never used them for what they're actually good at:

Hems that won't stay. Wrap dresses that gape. Strapless anything. Bra straps. Costume repairs ten minutes before you leave.

Durable Strength for structured fabric, Soft Hold for anything fine. Both discounted.

Washing extensions, short version:

Sulphate-free shampoo. Condition mid-length to ends only, never the root or the tape. Let them air-dry as much as you can. Brush from the bottom up with a loop brush.

That's most of it. The rest is just not being rough with them.

Office hair, no maintenance: clip-ins that go in before the first meeting and come out before dinner.

Fifteen years in, the thing we're proudest of isn't a product. It's that we still answer shade-match questions ourselves.

Send a daylight photo. We'll tell you honestly if we don't have your match, including when the answer is "don't buy this."

The attachment point is the tell. Always.

Not the length, not the shine, not the volume. Whether there's a visible line where the weft sits against your hair.

Ours lies flat because your own hair covers it from above and supports it from below. That's the entire design.

Silky straight is the least forgiving texture and the best test of an extension.

No wave to hide the transition, no movement to disguise where the weft sits. If it blends straight, it blends anywhere.
