HALO

Leave-In Quench Treatment · Hydrate System

Halo is a leave-in treatment that helps rescue dry, brittle hair between shampoo and conditioning services.

Sizige Halo Quench Treatment bottle

Product Overview

It restores softness, improves fluidity, and keeps hair smooth, responsive, and easy to manage throughout the day — without weight.

Halo is built for the stretch between services, where hair is furthest from its last conditioning treatment and most likely to feel rough or unmanageable.

Defined by Science

Halo supports the strand by:

  • Restoring softness to hair that has turned dry or brittle
  • Improving fluidity and movement through the length
  • Keeping hair manageable across a full day of wear
  • Delivering all of this without weight or build-up

Balanced by Design

Halo is for dry, brittle, or high-porosity hair that loses condition quickly between washes.

It is equally useful for anyone stretching time between services, where the routine is right but the interval is long.

How to Use

  1. Apply to damp or dry hair, concentrating through the mid-lengths and ends.
  2. Do not rinse.
  3. Reapply through the week as hair begins to feel dry.

Part of the Hydrate System

Halo is part of the Hydrate System, which builds softness and flexibility without weight or loss of natural movement.

Within the system, Halo is the between-services step — it holds the result the cleansing and conditioning stages created until the next one.
