What this is
Most shine products look good once.
Keratin Lock changes how hair behaves. It helps create a smoother, more controlled finish that holds up better between styling sessions, without feeling coated or heavy.
This is what makes the protocol last.
Where it fits
Keratin Lock is Step 4 of Keratin Protocol.
It comes immediately after Extend. Extend is the renewal step. Lock is the seal. It’s designed to finish the routine while hair is most receptive, so the result holds longer and looks more consistent.
If you want the full experience, start with the set.
How to Use
After Extend
Once Extend has been applied and combed through, apply Lock to damp hair. Comb through again. Do not rinse. Blow-dry and style.
As a daily blowout spray
Apply to freshly washed, towel-dried hair before other styling products. Comb through, then blow-dry and style.
Why it’s different
Lock is built for performance without weight.
It’s designed to support smoothness, shine, and control while keeping hair soft and touchable. The finish looks cleaner, lasts longer, and requires less “fixing” as the day goes on.
When to Reach for Keratin Lock
If blowouts look good at first but don't last
If frizz returns quickly after styling.
If shine fades unevenly.
If your hair behaves better on day two than day one.
Lock is the difference between a temporary finish and a repeatable one.
What’s inside and why
Keratin Lock is formulated to seal the cuticle, support softness and shine, and help hair stay controlled through styling.
This is a finishing step that works like a foundation.
FAQs
Do I need Extend to use Lock?
No. Lock works on its own as a blowout base spray. Extend makes the protocol stronger and more “freshly done” feeling. Together is the full result.
Can I use Lock every time I style?
Yes. That’s one of its best roles.
Will it weigh my hair down?
No. Use a light, even mist and comb through for consistent distribution.
