Truly Seamless Tape-In Extensions — Double-Sided 20-21″ 42.5g
Original price was: $199.95.$139.97Current price is: $139.97.
Salon-quality tape-in extensions in 100% double-drawn Remy human hair, 20–21″. Instant length and volume with our double-sided method — supported top and bottom by your own hair, so the blend is completely undetectable and gentle enough to wear again and again.
Double-sided tape-in extensions from Truly Seamless add length and volume with a flat, low-profile weft. Each set is 42.5 grams of 100% double-drawn Remy human hair at 20 to 21 inches.
Why Truly Seamless
Traditional tape-ins sandwich your hair between two sticky tabs — heavy, visible, and hard on your hair. Our double-sided method is supported on the top and bottom by your own hair, so the weft lies flat and disappears. The result is a blend no one can detect, with none of the tension that causes breakage.
What you get
42.5 grams of 100% double-drawn Remy human hair in your chosen shade and texture, 20–21″ — falls to roughly mid-back. Reusable 2–3 times with proper care.
Care & maintenance
Treat them like your own hair: gentle sulfate-free shampoo, condition mid-to-ends, air-dry when you can, and store flat. With the right care, your set lasts through multiple re-applications.

How our double-sided tape-in extensions work
Each Truly Seamless weft measures 3 inches wide and half an inch tall. Two wefts sit side by side across the back of the head, which gives about 6 inches of coverage. Instead of sandwiching a section of hair between two tabs, our weft is supported on the top and bottom by your own hair. That is why it lies flat. Read the full comparison in our guide to the sandwich method versus Truly Seamless.
Choose your shade and texture
Pick from Body Wave or Silky Straight. Silky Straight holds a natural bend when you air-dry it. Shades range from 1B Off Black, 2 Dark Brown and 4 Medium Brown to 10 Light Brown, M4/27 Brownie/Caramel, 6A/22 Ash Blonde Mix and red tones. Only shades that are in stock are listed, and once a shade sells out it is gone.
Placement and installation
Wefts go in horizontal rows across the back of the head, below the crown, with your own hair clipped up and out of the way. Thin sections keep each weft well covered. Many clients book a stylist, and our at-home application guide explains each step if you prefer to do it yourself.
Care and reuse
Wash with a gentle sulfate-free shampoo, keep conditioner on the mid-lengths and ends, air-dry when you can, and store the hair flat. With proper care a set can be reused two or three times with fresh tape. The Re-Tape Kit has what you need.
