Product Overview
It reduces irritation, tightness, and imbalance, making the scalp feel better and more settled in the same step you are already performing.
Seren is suited to reactive, tight, or easily irritated scalps, and to routines that are working well on the hair but asking too much of the skin underneath it.
Defined by Science
Pulsar Seren supports the scalp by:
- Easing irritation and the sensation of tightness
- Supporting balance where reactivity or dryness occurs
- Delivering comfort quickly rather than over weeks
- Leaving hair movement, styling, and finish unaffected
Balanced by Design
Seren is for anyone whose scalp limits what their routine can do — sensitivity, tightness, or discomfort that makes stronger products hard to tolerate.
Adding it to an existing product is often what allows that product to stay in the routine at all.
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
Seren 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, Seren is the soothing expression — the modifier reached for when scalp comfort is the outcome that needs raising.
