How Many Tape-In Extensions Do I Need? Letâs Figure It Out Together
Youâve picked out tape-in extensionsâyay! Honestly, theyâre one of the best choices out there. Lightweight, reusable, and practically invisible when installed properly. But here comes the million-dollar question every client (and stylist) asks: How many do I actually need for my head?
Spoiler alert: thereâs no single answer. It depends on your hair thickness, your current length, and the kind of transformation youâre dreaming about. So, letâs sit down, grab a coffee, and decode this together.
First Things First: What Counts as âOneâ?

A quick refresher. Tape-in extensions come in small panels with adhesive at the top. To apply them, stylists âsandwichâ a section of your natural hair between two panels.
-
One sandwich = 2 tape panels.
-
Most packs come with 10 to 20 sandwiches.
-
A âfull headâ usually means anywhere between 40 and 60 sandwiches.
Once you understand that, the math becomes way easier.
The Quick Cheat Sheet
-
For a boost of volume only: 20â30 sandwiches (thatâs 1â2 packs).
-
For length + volume: 40â60 sandwiches (2â3 packs).
-
For thick or short natural hair: 70â80 sandwiches (3â4 packs).
But donât run off just yetâthe details matter.
Why Itâs Not the Same for Everyone
You know how two people can order the same haircut but walk out looking completely different? Extensions are the same way. The number youâll need depends on:
-
Hair density (how much natural hair you have).
-
Your starting length.
-
Your end goalâsubtle fullness or dramatic length?
-
Head size and sectioning space.
Letâs unpack these one by one.
Factor 1: How Thick Is Your Natural Hair?
Thin/Fine Hair
If your strands are fine and your ponytail is on the smaller side, you donât need loads of tape-ins. In fact, adding too many can overwhelm your natural hair. Around 20â40 sandwiches is usually plenty.
Medium Hair
This is the âaverageâ category most clients fall into. Youâll usually need 40â60 sandwiches to balance out length and volume.
Thick or Coarse Hair
The more hair you naturally have, the more extensions youâll need to blend it. Otherwise, youâll see a harsh line where your natural hair ends. For thick hair, 60â80 sandwiches is the sweet spot.
Factor 2: Whatâs Your Current Hair Length?
-
Short bobs: These need more sandwiches to cover blunt edges. Think 60+ sandwiches to blend properly.
-
Shoulder length: A solid mediumâ40â50 sandwiches usually does the trick.
-
Medium to long hair: Sometimes 30â40 sandwiches is enough if youâre only adding fullness, not length.
Factor 3: Whatâs Your Dream Look?
This is where goals matter more than rules.
-
If you just want extra fullness: 20â30 sandwiches is all you need. Perfect for clients who love their length but want thicker braids, ponytails, or blowouts.
-
If you want both length and fullness: 40â60 sandwiches is the standard âfull headâ install.
-
If you want a big, bold transformation: 70â80 sandwiches is your go-to. Thatâs when youâre going from a blunt bob to mermaid waves.
Factor 4: Head Size & Sectioning
Itâs not something we think about often, but head size plays a role. A petite client with a small frame may look amazing with fewer sandwiches, while someone with a lot of surface area needs more to cover every section seamlessly.
Thatâs why stylists always do a consultation first. Charts are helpful, but hands-on assessment is the only way to nail the right number.
Packs vs. Sandwiches: Making It Simple
Letâs translate this into âpacks,â since thatâs how most extensions are sold.
-
20 sandwiches (10 pairs) = 1 pack
-
40 sandwiches (20 pairs) = 2 packs
-
60 sandwiches (30 pairs) = 3 packs
-
80 sandwiches (40 pairs) = 4 packs
So if your stylist tells you that youâll need 60 sandwiches, thatâs usually about 3 packs.
A Stylistâs Real Talk
When clients ask me this in the salon, I usually smile and say:
âIt dependsâdo you want to feel like yourself but fuller, or do you want your friends to do a double-take when you walk in the room?â
Because honestly, thatâs what it boils down to. Subtlety takes fewer sandwiches. Drama takes more.
A Tangent: Donât Forget Hair Quality
Hereâs a little industry secret: you can have the âright numberâ of tape-ins, but if the quality of the hair isnât good, it wonât matter. Cheap extensions might look shiny at first but can mat, shed, or lose their softness quickly.
High-quality hair (like Remy, ethically sourced, cuticle-intact) means you get to reuse it 2â3 times, which makes the investment worth it. So yes, the number of sandwiches mattersâbut so does the quality.
