A post-color shampoo is specially made to protect and prolong your hair color by cleansing gently while locking in pigment. The 2.Oh! Post Color Shampoo features a Color Protect Compound and a pH-balanced formula (4.5) that helps seal the cuticle after coloring, preserving color and boosting shine.

Its Tri-Surfactant Formula cleans effectively without harshness, while argan oil and glycerin nourish, soften, and reduce frizz. This shampoo is a must-use for everyone who colors their hair—whether you’re covering greys, sporting cool blondes, rich browns, bright reds, or fun fashion shades. It works after any hair coloring service to lock in color and maintain hair health.

The best shampoo after coloring is one that keeps your hair color vibrant and your hair healthy. The 2.Oh! Post Color Shampoo does both, thanks to its Color Protect Compound, pH 4.5 formula, and Tri-Surfactant cleansing system. It prevents color from fading and helps maintain softness and shine.

It’s ideal for every type of colored hair—from natural tones to bold colors, including greys, blondes, deep browns, reds, and vibrant or pastel hues. This is the shampoo to choose when you want long-lasting color and soft, smooth strands from root to tip.

Your first wash after coloring should always be with a shampoo designed to protect color. The 2.Oh! Post Color Shampoo is ideal for immediately after coloring because it has a pH of 4.5 to rebalance the hair and lock pigments in.

The Color Protect Compound prevents early fading and keeps your shade— whether it’s grey coverage, blonde balayage, chocolate brown, red, or bold violet—rich and even. It cleans gently while preserving color and restoring moisture, making it the best first step after any coloring service.

Use a post-color shampoo like 2.Oh! Post Color Shampoo from your very first wash after dyeing and continue using it regularly to extend the life and brightness of your color. It’s designed for all types of colored hair, whether you’re covering greys, maintaining chocolate tones, caring for ash blonde, or enjoying bold fashion colors.

It keeps color true, reduces dullness, and improves hair texture—making it a smart choice even weeks after coloring, especially if you're looking to stretch that salon-fresh look a little longer.

Yes—each serves a different purpose. The Post Color Shampoo is designed to lock in hair color, protect pigment, and balance pH to reduce fading—making it a must for anyone with colored hair, from root touch-ups and grey coverage to bold or pastel color.

The Reconstruction Shampoo focuses on repairing damage, softening texture, and building strength with its Tri-Surfactant Formula + argan oil + glycerin. It does not contain color-locking elements, so for the best results you can alternate both—one for color care and the other for long-term repair—as part of your Healthy Hair Ritual.
