What this is
Treatments don’t disappear overnight. They fade gradually.
Keratin Extend is designed to reinforce the finish between treatments and between “great hair weeks.” With consistent use, hair stays smoother, looks brighter, and feels easier to control without feeling heavy or coated.
It doesn’t reset your hair. It restores it.
How to Use
After cleansing and conditioning, towel-dry hair.
Mist Extend evenly through mid-lengths and ends. Comb through so coverage is consistent.
Activate with heat as you blow-dry or style.
Follow with Keratin Lock to seal the finish and improve longevity.
Why it’s different
This step is designed to respond to heat.
Extend is meant to work with your styling routine, not compete with it. When you activate it with heat, hair becomes smoother, more controlled, and more reflective, with less effort and fewer “fix-it” passes.
This is the difference between hair that looks good once and hair that keeps behaving.
When to Reach for Keratin Extend
If frizz returns fast between salon visits.
If hair starts feeling rough again.
If shine looks cloudy.
If the blowout stops holding the way it should.
Extend is the weekly reset that doesn’t strip the hair.
What’s inside and why
Extend is formulated to reinforce structure and refine the finish without heaviness, so hair stays smooth, luminous, and easier to style.
This is the protocol’s renewal step.
FAQs
Do I use Extend every wash?
Most people use it weekly. If hair is especially reactive, you can use it as needed.
Do I have to use heat?
Heat activation is the point. Extend is designed to be activated during blow-drying or styling.
Do I need Lock if I use Extend?
For the best longevity, yes. Extend reinforces the finish. Lock seals it so it holds longer.
