A BTX treatment is hair botox. "BTX" is simply a short way of writing "botox", and it's the name many salons use for a deep-conditioning, smoothing treatment that fills in dry, porous hair and calms frizz. It contains no botulinum toxin and no needles are involved. Below you'll find what BTX does, how it compares with keratin, how long it lasts and how to do it at home.

What does BTX mean in hair care?
BTX is shorthand for botox. In hair care it doesn't mean the injectable used in skin clinics. It's a nickname for a treatment that makes hair look fuller, smoother and more "filled in". You'll often see the term on salon menus and product labels, and in Spanish and Portuguese as "BTX capilar". Hair BTX, hair botox, botox hair treatment and BTX keratin are different names for the same kind of treatment.
To be clear, hair botox (BTX) has no botulinum toxin in it. It's a topical treatment made from proteins, oils, waxes and conditioning ingredients. You can read exactly what goes into a formula in our guide to Japanese botox hair masks.
What does a BTX treatment do?
Hair that's been colored, bleached, heat-styled or exposed to sun and humidity gets rough and porous. The outer layer (the cuticle) lifts, moisture escapes and frizz takes over. A BTX treatment is designed to:
- Reduce frizz by smoothing the hair surface.
- Add softness and shine, so hair feels silkier and reflects more light.
- Improve manageability, so hair is easier to brush and style.
- Make hair look fuller, because proteins settle into dry, porous spots.
What it doesn't do: BTX is not a permanent straightener. Heat-activated versions can make hair noticeably sleeker, but the final look depends on your natural texture, the condition of your hair and how you apply it.
What's in a BTX treatment?
Every brand has its own formula, but most BTX treatments combine three types of ingredients:
- Proteins such as keratin and collagen, which support weakened strands.
- Lipids such as beeswax, oils and butters, which coat and seal the cuticle.
- Conditioning extracts, such as seaweed or other plant extracts, for hydration and shine.
Our Japanese Botox Keratin Hair Mask, for example, uses keratin, collagen, beeswax and seaweed extracts, and its product page lists it as formaldehyde-free, paraben-free and cruelty-free.
BTX vs keratin vs tanino: what's the difference?
People often mix these three up. Here's a simple side-by-side.
| BTX (hair botox) | Keratin treatment | Tanino | |
|---|---|---|---|
| Main goal | Deep conditioning, smoothing, frizz control | Smoothing, often with more straightening | Smoothing and softness while keeping natural texture |
| Key ingredients | Keratin, collagen, waxes, oils | Keratin and smoothing agents | Botanical tannins, keratin, oils |
| Flat iron? | Usually yes (heat-activated) | Usually yes | Often no |
| Best for | Dry, frizzy, porous or chemically treated hair | People who want sleeker, straighter hair | Curly or coily hair, or anyone who wants to skip the iron |

Who is a BTX treatment good for?
BTX is a good fit if your hair is:
- Frizzy, especially in humid weather
- Dry, rough or dull
- Colored, highlighted or chemically processed
- Thick or textured and hard to manage
If your hair is very fragile or heavily bleached, you can still use it, but go gently with heat. Always do a strand test first, and turn the flat iron down for fragile hair.
How to do a BTX treatment at home, step by step
You don't need a salon appointment. These steps follow the directions on our Japanese Botox Keratin Hair Mask:
- Wash with a clarifying shampoo. This removes buildup so the treatment can do its job. Towel-dry your hair.
- Section your hair. Four to six sections make it easier to cover every strand.
- Apply the mask evenly, avoiding the scalp. Work it from just below the roots to the tips, then comb it through.
- Leave it on for 30 to 60 minutes. Coarse, thick hair can take the full time. Fine or chemically treated hair may need less.
- Rinse about 50%. Don't rinse it all out. You want some product left in the hair.
- Blow-dry completely. Hair must be fully dry before the next step.
- Flat iron thin sections 10 to 15 times. The product page allows up to 450°F, but adjust the temperature to your hair's condition and use less heat on fragile or bleached hair.

How long does a BTX treatment last?
According to our product page, results may last about 8 to 12 weeks. How long yours last depends on your hair type, its porosity, how often you wash and your aftercare. Two things help most: a sulfate-free shampoo and conditioner, and less heat between treatments. Our hair botox aftercare guide covers the full routine.
BTX at the salon vs at home
A salon BTX treatment gives you a stylist's hands and judgment, which helps if your hair is very damaged or you're unsure about heat. The downside is price and time, and both vary a lot by salon.
An at-home BTX treatment uses the same steps: wash, apply, process, rinse partly, blow-dry and flat iron. You control the timing and the heat, and you can do it whenever suits you. If you've ever had a salon BTX and liked it, doing it at home is a natural next step.
Common BTX mistakes to avoid
- Skipping the clarifying wash. Product buildup can block the treatment.
- Rinsing out all the product. Rinse only about half.
- Flat ironing damp hair. Blow-dry completely first.
- Too much heat on fragile hair. Lower the temperature and do a strand test.
- Going back to a harsh shampoo. Sulfates can shorten your results.

FAQ: BTX hair treatment
Is BTX the same as botox for hair?
Yes. BTX is short for botox, and in hair care both names describe the same kind of conditioning, smoothing treatment. Neither contains botulinum toxin.
Does a BTX treatment straighten hair?
Not permanently. It reduces frizz and smooths the hair surface, and heat-activated versions can make hair look sleeker. The result depends on your natural texture and how you apply it.
Can I do BTX on bleached or colored hair?
Yes. Our product page says the mask can be used on color-treated, highlighted and bleached hair. Chemically processed hair can be more sensitive to heat, so strand test first and lower the flat iron. More in our article on hair botox on color-treated hair.
Is BTX keratin different from a BTX treatment?
"BTX keratin" usually just means a BTX treatment that contains keratin, which many do. Our Japanese Botox Keratin Hair Mask combines both in one heat-activated formula.
Do I need a flat iron for BTX?
For heat-activated BTX, yes. The flat iron seals the treatment into the hair. If you'd rather skip the iron, a tanino treatment is the no-heat alternative.
