Product Overview

The Original Color Out System (COS) is the trusted solution for removing unwanted semi-permanent and permanent hair color. Unlike bleach or harsh chemical removers, COS works gently to lift color from the hair shaft without ammonia, leaving your hair healthier and ready for a fresh start. This 8 fl oz kit contains everything you need for a single application, making it perfect for at-home color correction.

Key Features and Benefits

  • Guaranteed Authentic Original Formula: COS is the original color removal system trusted by professionals and consumers for years. You receive the genuine product, not a copycat.
  • Ammonia Free: The gentle, ammonia-free formula minimizes damage and irritation, making it suitable for all hair types, including color-treated and chemically processed hair.
  • Removes Both Semi & Permanent Color: Effectively strips away unwanted artificial color, whether it's a semi-permanent dye or a stubborn permanent shade.
  • Safe and Easy to Use: Simple step-by-step process can be done at home without professional assistance. No harsh fumes or complicated mixing required.
  • Preserves Hair Integrity: Unlike bleach, COS does not lighten natural hair pigment, so your natural color remains intact. It targets only the artificial dye molecules.

How to Use

For best results, follow the included instructions carefully. Typically, you mix the activator and color remover in a non-metallic bowl, apply to dry hair, and process for up to 20 minutes. Rinse thoroughly, then shampoo and condition. For stubborn colors, a second application may be needed. Always perform a strand test first to gauge the result.

Who It Is For

COS is ideal for anyone who needs to correct a hair color mistake, remove buildup from multiple dye applications, or simply lighten their current color before trying a new shade. It suits all hair types and textures, including natural, relaxed, or permed hair. Whether you're a home colorist or a professional stylist, COS provides reliable results.

Why Choose This Product

With countless color removers on the market, COS stands out for its proven track record and gentle formula. It is ammonia-free, so it's less damaging than bleach-based removers. The authentic original formula ensures consistent performance. Plus, it saves you a trip to the salon, giving you control over your hair color journey.
