One-sided extension tape has adhesive on a single face and a fabric or poly backing on the other. It is used to re-back a weft, repair a lifted edge, or build a weft up, not to attach hair to a head. A tape-in install needs double-sided tape.
We do not sell single-sided tape
Our catalogue is double-sided tabs, a remover, an application tool and the kits that combine them. If you need a single-face tape for weft repair, a hair supply retailer is the right place and we are not. What we do make
This query splits into two groups. One group knows exactly what single-sided tape is and wants it for weft work. The other group is about to install tape-ins and has picked the wrong product name.
Both are worth serving properly, so this page covers what single-face tape does and then points the second group to the right thing.
The three real jobs
| Job | What it involves |
|---|---|
| Re-backing a weft | The adhesive strip on a used weft is spent. A single-face tape lays a fresh backing down so the weft can take a new double-sided tab |
| Repairing a lifted edge | A corner that has peeled away from the weft, stabilised so it doesn't travel further along the track |
| Building or reinforcing a weft | Weft construction and reinforcement work, usually at a hair supplier rather than at a station |
All three are weft work. The tape is acting on the hair piece itself rather than on the interface between the piece and someone's head, which is why it has adhesive on only one side.
Why an install needs two faces
A tape-in holds because a section of natural hair sits clamped between two adhesive faces that have bonded around it. One face has nothing to bond to on the other side, so there is no sandwich and nothing holding the section. Single-face tape stuck to a head is a weft resting against hair.
Which one do you need
Attaching hair to a head means double-sided. Working on the weft itself means single-sided. If you're about to do an install, you want tabs.The full diagnostic
The re-backing decision
Re-backing a weft is real work and it is sometimes worth doing on good hair. It is also frequently not worth doing. A weft that has been through three or four cycles has usually lost enough density at the track that the short answer is a new weft rather than a repair.
Our position on this is easy to state because we don't sell either: we sell the tabs that go on the weft, not the weft and not the tape that repairs it.
Why this page does not sell you anything
We don't make single-sided tape, we have no plans to, and we're not about to recommend a brand of it we haven't used.
We also do not sell hair, so we have no interest in telling you whether to re-back a weft or replace it. That is a call for you and whoever supplies your hair.
If you landed here about to do a tape-in install, the tabs are what you want and they're double-sided.

- Replacement tape for tape-in extensions. Frames tabs as the recurring consumable in a move-up cycle and works out the annual pack count.
Questions we get asked
Can I use one-sided tape to install extensions?
No. There is no second adhesive face for the natural hair to bond against, so there's no sandwich and nothing holds.
What is single-sided extension tape used for?
Weft work: re-backing a spent weft, repairing a lifted edge, and weft construction or reinforcement.
Do you sell it?
No. We make double-sided tabs, a remover and an application tool. A hair supply retailer is the right place for single-face tape.
Is re-backing a weft worth it?
Sometimes, on good hair that has not lost density at the track. After three or four cycles a new weft is usually the better call.
