Tape-in extensions are flat wefts of hair with a strip of double-sided adhesive along the top edge. A thin section of your own hair is sandwiched between two wefts, and the tape bonds them together around it. They are worn for six to eight weeks, released with a solvent, re-taped, and the same hair is reinstalled.
Tape-ins are the extension method with the most vocabulary attached: sandwich, tab, weft, move-up, dwell time. This page defines the method and points you at the words.
Tape-in extensions, defined
A tape-in extension is a semi-permanent hair extension made of two parts: a weft, which is hair joined along a flat base strip, and a tab of pressure-sensitive adhesive on that base. Two wefts pressed together around a thin slice of natural hair make one bond, called a sandwich.
Your own hair isn't glued or coated. It sits between two adhesive faces that are bonded to each other, which is why a solvent can take the sandwich apart again without cutting anything. The hair on the weft is usually human hair bought from a hair brand. The tape is a consumable, replaced every cycle.
You'll also hear tape-ins, tape hair extensions and tape wefts. Wearers usually say tape-ins; stylists talk in sandwiches and tabs, because that is what they count and buy.
How the tape holds
Tape-in adhesive is pressure-sensitive: it does not cure or set chemically. It holds through contact area and the pressure applied at install, then stays tacky until a solvent releases it. Oil, early water, heat at the bond and tension all weaken it, which is why aftercare is mostly about keeping the bond line clean and dry.
That chemistry explains the rules people are given: no washing for 24 hours after install, no oil-based products at the root, and a remover rather than force at the end. The adhesive itself is covered in more depth in our entry on hair extension adhesive.
The tape-in cycle in one line
A tape-in cycle is install, six to eight weeks of wear, then a move-up: every sandwich is released with remover, each weft gets a fresh tab, and the hair goes back in close to the scalp. Your own hair keeps growing and carries the bond down, which is what sets the interval.
- Install: rows from the nape up, a thin section per sandwich, pressed with a tool.
- Wear: six to eight weeks, oil kept off the bond.
- Removal: solvent on both sides of the tab, a short wait, a rattail guided between the wefts.
- Re-tape: old tab off, base cleaned, new tab on.
- Reinstall: same hair, back near the root.
Each of these words has its own entry or hub definition on the glossary.
How tape-ins differ from other methods
Tape-ins lie flatter than beads or bonds, need no heat at install, and reuse the hair at every cycle. They need a move-up more often than some methods and dislike oily scalps. Clip-ins come out daily; keratin bonds are applied strand by strand with heat; hand-tied wefts are sewn to a beaded row.
That is the one-paragraph version. The method-by-method table, with wear time, install time and who each suits, is in tape-in vs other extension methods.
What Vanity makes, and doesn't
Vanity Hair Solutions makes the tape side of tape-ins, not the hair: Replacement Tape Tabs (60 tabs, 4 cm x 0.8 cm, built for a six to eight week hold), The Clean Remover, an oil-free solvent, and the tool to press them. The tabs re-tape double-sided wefts from other brands.
Cost, damage, who tape-ins suit and who should skip them are all answered in full in tape-in hair extensions explained.

Questions we get asked
Are tape-in extensions permanent?
No. They are semi-permanent: worn for six to eight weeks, then removed with a solvent and either reinstalled or left out.
What is a tape-in sandwich?
One bond: two taped wefts pressed together with a thin slice of natural hair between them. A 60-tab pack makes 30 sandwiches.
Is the hair or the tape reused?
The hair. Tape bonds once and is replaced at every move-up; a good weft goes back in cycle after cycle while its base stays intact.
Can tape-ins go in short or fine hair?
Fine hair often suits them because the tab is flat. Very short hair is limited by whether your own hair can cover the tab.
