Shampoo Bars for Color Treated Hair

Color-treated hair has one enemy above all others - sulfates. They strip the hair shaft aggressively and take your color with them.

Le Silo Bleu's shampoo bars for color treated hair are completely sulfate-free, formulated with plant-based cleansing agents, gentle enough to clean thoroughly without accelerating fade. The Purple Toning bar is the star of this collection - neutralizing brassiness in blonde, silver, and highlighted hair while cleansing. The Nourishing bar keeps color-treated hair moisturized and healthy between toning washes. The Balancing bar is the everyday gentle cleanse that maintains color without any buildup. 

All made by hand in small batches in New York. Wash in lukewarm water and rinse.  Use cool temperature water, as that matters as much as formula when you're protecting color.

What Makes Our Haircare Different?

We believe haircare should be easy to choose, effective to use, and thoughtfully formulated.

While many solid bars focus on one-size-fits-all formulas, our collection is designed as a system. Each shampoo bar is formulated for a specific scalp or hair need, and each conditioner bar is designed to pair based on hair length and moisture needs so you can build a routine that actually makes sense.

Our botanical haircare also includes targeted leave-in products such as detangling mists, scalp sprays, and nourishing oils designed to support the routine between washes. These lightweight formulas help soften strands, improve manageability, and support balanced scalp care.

We take a botanical-forward approach, using gentle cleansers, targeted plant ingredients, and conditioning agents selected for how they support real hair concerns. You’ll also find clear guidance throughout our site, from pairing charts to ingredient explanations, because understanding what you’re using matters.

Our products are made in small batches, thoughtfully balanced, and intentionally simple to use. Just well-designed botanical haircare that fits into real life routines.
