Product Overview
It carries targeted proteins that bond where damage is greatest, building resilience from inside the strand rather than coating it.
Kera is suited to hair that has been chemically processed, heat-styled, or mechanically stressed, and to anyone whose hair stretches, snaps, or loses shape under tension.
Defined by Science
Pulsar Kera supports the strand by:
- Directing protein support to the areas of greatest damage
- Rebuilding internal resilience rather than surface stiffness
- Improving resistance to breakage under brushing, heat, and tension
- Reinforcing structure without leaving hair rigid or brittle
Balanced by Design
Kera is for compromised, over-processed, or fragile hair that needs structural support added to an existing routine.
Because protein need changes as hair recovers, Kera can be increased, reduced, or paused without disrupting the routine it sits inside.
How to Use
- Add a small amount to a single application of any Sizigē shampoo, conditioner, treatment, or styling product.
- Blend in the palm before applying, then use the product as normal.
- Use alone for a single focus, or combine Pulsars to address more than one goal.
- Adjust the amount up or down as your hair's needs change.
Part of the Pulsars Modify System
Kera is part of the Pulsars Modify System — concentrated modifiers that let any Sizigē product be tuned to the individual without changing the routine around it.
Within the system, Kera is the strength expression — the modifier reached for when structural integrity is the outcome that needs raising.
