How often should I use the Rosemary Leave-In Mask?

For best results use 1–2 times per week or as needed depending on your hair type — e.g. fine or oily hair may benefit from once per week or every other week, while dry or textured hair can tolerate more frequent treatments.

Answer


Should I apply the mask on wet or dry hair — and when during my wash routine?

Apply the mask after shampooing without conditioner, on damp or dry hair and leave in your hair. Shampooing first removes buildup, allowing the mask’s actives to penetrate more effectively.

Answer


How long should I leave the mask on for optimal results?

Leave in for at least 4-5 minutes to let ingredients absorb before any other treatment or proceeding to styling/brushing/additional regimen steps. Do not wash out.

Answer


Can I use the Rosemary Leave-In Mask if I have color-treated or chemically-treated hair?

Yes. The Rosemary Leave-In Mask is generally safe for color-treated or processed hair, and can help restore moisture, strength, and silkiness after coloring.

Answer


What kind of results should I expect — and how long until I see them?

With consistent use, you should notice improved softness, smoother strands, better manageability, less dryness or frizz — and over time, potentially stronger, more resilient hair.
