What we mean by Non-Toxic
We avoid toxic preservatives like phenoxyethanol, that studies have shown to disrupt your hormones and reproductive health.
Instead we include a preservative derived by grapefruit seeds. Safe for your hair, scalp, and the planet.
Is it safe for color treated hair?
Yes! Our shampoo bars are pH balanced and free from sulfates, silicones, and harsh ingredients, making them safe for color-treated and chemically processed hair. These bars offer a better alternative to traditional liquid products.
How do I store a shampoo bar for Travel?
Our travel cases are designed to fit both a full-size bar and a bar bag for easy, mess-free storage on the go. If you're traveling, pairing the case with the bar bag lets you hang-dry your bar right over the shower handle—no shelf, no stress and spill-free for wherever you’re headed.
What is a shampoo bar?
It’s just like your traditional liquid shampoo—just without the plastic bottle, water, and fillers. Our bars are concentrated, soap-free formulas made with gentle plant-based surfactants (the molecules that create a cleansing sudz) and nutrient-rich ingredients to nourish your scalp, without the waste.
