Yes, our products are vegan, meaning they do not contain any animal-derived ingredients or byproducts. This includes ingredients such as dairy, honey, and other animal-derived substances like gelatin, lanolin, and carmine, which we proudly avoid.

Yes, we are proudly cruelty-free! We never test on animals and are certified by PETA. We love our pets too much to do anything else!

Absolutely! Our products are gluten-free, paraben-free, sulfate-free, and free of shark squalene, and sodium chloride. We exclude all ingredients potentially toxic to humans, rare vintage couture and our dear environment.

We are proudly made in the USA using globally sourced ingredients and materials.

Our products are free from parabens and rely on a botanical preservation system. As a result, some natural separation may occur over time. Simply shake the product well to restore its original consistency.

If it is leaking, you may not be pressing down correctly. Hold your finger level and press down firmly. Avoid holding the bottle upside down while spraying. If the sprayer appears to be clogged or has buildup, run it under hot water until the buildup dissipates from the valve.

Reconstructing Hair Masque uses an airless pump system that may be prone to creating a vapor lock. Tap the bottle hard on the corner of the counter and try pumping again. If there is still product left in the bottle that won’t evacuate, you can use a screwdriver to pop off the top portion of the bottle. You won’t be able to reattach it, but you will be able to scoop out the remaining product.

We recommend that you unscrew the pump. Add a little water and shake the bottle. Due to the product's high concentration, adding a small amount of water will not affect its performance.

Ensure the pump is unlocked and then begin priming the pump. This involves quickly pressing the actuator several times in succession to activate the pumping mechanism. It may take a few tries. If you are still not spraying, unscrew the sprayer and ensure the dip tube is attached properly. Then, run the tube under hot water and reassemble.

You may have noticed that our fabulous products have been wearing fewer layers lately. As we seek ways to evolve and care for our beautiful planet, we have made a choice to eliminate the cellophane wrap from our outer packaging (crinkle, crinkle, goodbye).

You may also notice some subtle packaging refinements, but rest assured, these are a testament to our commitment to keeping our beloved brand in perfect harmony with the world, ensuring global compliance. Our soft-touch, FSC-certified Forest Stewardship Council-approved boxes will enhance the wonderful hair care experience you deserve. These sleek and sophisticated boxes have been ship-tested, shelf-tested, and sealed with a sticker to ensure they maintain a beautiful and luxurious quality.
