Sizige Equinox Recovery Mask bottle

Product Overview

This mask delivers layered protein, bioferment, and botanical support during extended contact, helping hair feel stronger, more cohesive, and better able to withstand daily stress. The experience is fortifying yet composed — supporting strength without rigidity, dryness, or loss of movement.

Equinox Mask is designed for hair that benefits from deeper reinforcement while maintaining flexibility and control.

Defined by Science

Equinox Mask helps hair:

  • Feel reinforced and more resilient
  • Improve elasticity and fiber cohesion
  • Detangle more easily with controlled slip
  • Maintain flexibility while increasing strength
  • Appear smoother, more stable, and better supported

The experience is restorative and substantial, delivering strength that integrates into the hair rather than sitting on the surface.

Guided by Nature

Equinox Mask is structured around layered strengthening support designed to reinforce hair integrity while preserving flexibility and movement.

Bamboo Bioferment
Serves as a foundational strength-supporting element, contributing to resilience, structure, and durability within the hair fiber.
Keratin, Wheat Proteins & Silk Amino Acids
Reinforce internal cohesion and surface integrity, helping hair feel stronger, more stable, and less prone to breakage.
Baobab Protein & Camellia Oils
Support elasticity, flexibility, and smoothness — ensuring strength integrates seamlessly without stiffness or rigidity.

Together, these elements deliver strengthening care that feels composed, balanced, and wearable.

Balanced by Design

Equinox Mask is for hair that requires deeper strengthening support.

It is well suited for hair that feels weakened, overextended, or less resilient, as well as hair exposed to heat, styling, or environmental stress. Equinox Mask supports reinforcement without sacrificing flexibility or feel.

How to Use

  1. Apply to clean, damp hair and distribute through lengths.
  2. Leave on for several minutes, then rinse thoroughly.
  3. Use weekly or as needed for strengthening-focused treatment.

Part of the Strengthen System
