FAQ

We recommend using the Foundation Mask 1-2 per week, or as needed, depending on how much hydration your hair needs. If your hair is feeling especially dry or stressed, you can use it more frequently until things feel balanced again.

The Foundation Mask is a deeper treatment—it’s more concentrated and designed to deliver an extra boost of hydration and repair. Think of it as your weekly reset, while the conditioner is your everyday maintenance.

After using our Foundation Shampoo, wring out excess water. Then, apply this moisture-rich formula and comb through. Leave on for 5-10 min for extra hydration. Rinse out thoroughly.

Jill N. (5/5)

Great Smell and Good Feel!

"I am new to Rōz and decided to do the “try before I buy” approach. I have only had a chance to shampoo and condition once since receiving it a couple of days ago. I decided to start with the foundation mask because my hair has been so dry due to hard water and aging. I can say that I can already see how over time Rōz will improve my hair. The Foundation Mask smells great and my hair felt good after one use. There is less frizz already!"

Q&A

Instead of salt and pepper strands, my natural color has grown in as what I call silver and gold. The silver strands grab the color of any color ingredient in hair products so I tend to use clear or white products. Are there any colorants in your mask? Is it safe for silver hair?
Hi Bonnie! Thanks so much for your question! Our products are formulated without added colorants and are designed to be color-safe, so they should be totally safe on your silver hair. The mask is free from sulfates, parabens, and silicones, which helps prevent dryness and frizz, keeping hair hydrated and smooth while protecting color. Feel free to reach out to us at hello@rozhair.com if you have any other questions! Xx, Team RŌZ
can the foundation mask replace a conditioner, or do you use this alongside a normal shampoo/conditioner routine?
Hi Brigid, Foundation Mask works beautifully in place of conditioner whenever your hair needs an extra dose of hydration. Just cleanse your hair with Foundation Shampoo and follow with Foundation Mask, as you would conditioner. There's no need to wear it outside of the shower to achieve instantly hydrating results.
Is the hair mask scented? If so, what is the scent and has strong is it?
Hi Sue! Thank you so much for reaching out and expressing interest in our products! Our Foundation Mask contains the same signature scent as the rest of our effortless essentials. Inspired by the wildflowers and misty mountains of Big Sur, CA, our scent has subtle notes of Vetiver and Citron.
