Frequently asked questions

Our Hair Mask is customized to your hair needs and uniquely formulated with the ideal level of moisturizing ingredients to hydrate and repair the lengths and ends of your hair.


The Hair Mask should be applied to damp hair before you shampoo, and left on for up to 30 minutes (if you can spare the time). Usage and frequency will vary according to your hair needs, so check the notes that come with your order--they’ll give you some personalized pointers.


The best hair mask you can use is one that’s suited to your hair type, porosity, density, and local climate — which makes a custom Hair Mask the ideal choice. Geo-aggressors like pollution, pollen, and UV rays can impact the kind of care your hair needs. Your diet and lifestyle can impact your hair too, determining what nutrients your hair needs and what kind of stress it’s experiencing. We make it easy by factoring it all into your Custom Hair Mask to deliver the results you want. Take the consultation to find out what your hair needs.


Our Hair Mask contains the highest concentrations of your most-needed active ingredients, making it a potent pre-wash treatment to round out your hair care routine.


Unlike our Leave-In Conditioner, the Hair Mask should typically be left on for 5-30 minutes, as specified in the notes you receive with your products. It should always be followed by your Prose Shampoo and thoroughly washed out for the best results.


Yes — if you indicate that you have color-treated or dyed hair during the consultation, you can trust that your Hair Mask (and your whole routine) will be color-safe.


Prose custom hair masks work on straight (type 1), wavy (type 2), curly (type 3), and coily (type 4) hair. All of your Prose formulas are tailored for your individual hair density and porosity, so your hair gets the exact care that it needs. That means that your Custom Hair Mask will deliver the results you want, whether your hair is straight (type 1), wavy (type 2), or curly (type 3), or coily (type 4).


Creating your own Custom Hair Mask formula is as easy as 1, 2, 3:
1. Take your online consultation about your hair, lifestyle and environment to understand what kind of care your hair needs.
2. From your answers, we’ll create a personalized hair mask based on 85+ factors and formulated to support your unique needs at this moment in time.
3. You can always share feedback on your hair mask formula after every order using our Review and Refine® survey so we can provide evolving, custom-fitting care.


How frequently you use your Hair Mask will depend on your unique hair needs. External factors like pollution and humidity or stress levels and hormones can impact the sebum production (AKA, the natural oils your scalp produces to nourish your hair). Your unique Hair Mask formula will take all of that into account to keep your scalp happy and balanced — and your hair healthy.


At Prose, we only use ingredients that are high quality and highly effective. That means that every ingredient in your Custom Hair Mask has been meticulously researched by our world-class R&D team and sustainably sourced from trusted partners around the globe. And because Prose formulas are always free from anything harmful, we never use ingredients like sulfates, parabens, phthalates, mineral oil, alcohol, or GMOs.


Prose is not intended to treat medical conditions. Our formulas are a 100% drug-free alternative to prescription products and OTC (over-the-counter) medicines. Instead, we use only the highest quality, naturally powerful and proven-effective ingredients to enhance shine, volume, hair health, and so much more.
