#AskThePros: Everything You Need to Know about the Prose Custom Pre-Shampoo Mask

January 15, 2020

4 Min read

Welcome back to #AskThePros, where The Pros—your support team of custom formula and hair experts—break down our biggest customer questions. This month, the spotlight’s on our Custom Pre-Shampoo Mask: a powerhouse treatment that targets your top hair or scalp needs. We’ll dive into how the Pre-Shampoo Mask fits into your routine, and why it’s the perfect complement to your Prose Custom Shampoo and Custom Conditioner.

What exactly is the Prose Pre-Shampoo Mask?

Our Pre-Shampoo Mask provides supercharged care for your hair or scalp concerns, depending on your area of greater need. Used up to twice a week, this product goes beyond the typical wash; it contains the highest concentrations of your most-needed actives, along with additional ingredients that aren’t found in other products.

We offer two types of masks: a Hair Lengths Mask to repair and protect your strands, and a Scalp Mask to soothe and restore balance. Our algorithm will determine which is the right fit based on your consultation; as a heads up, since healthy strands require a healthy scalp and roots, any scalp issues will get top priority. Your mask label will indicate whether it’s for your lengths or scalp, and as always, your leaflet will provide detailed instructions.

How can the Pre-Shampoo Mask help with my scalp concerns?

Dealing with a flaky scalp, excessive sebum, or an all-too-sensitive scalp? A Scalp Mask can tackle all three, using our portfolio of clean and effective ingredients. And when we say that our Pre-Shampoo Mask is packed with active ingredients, we’re not kidding: a Scalp Mask can contain ten times the amount of the scalp-soothing complex found in our shampoo (CBD, Licorice and Pro-Vitamin B5). This concentration may be too high for a shampoo, but it’s just the right amount for a mask that’s used once to twice a week.

In addition to familiar active complexes to promote a healthy scalp and even encourage hair growth, your Scalp Mask contains unique ingredients such as Squalene. This non-irritating moisturizer and soother is even effective for those with dermatitis and psoriasis. Another top-performer is Vitamin F—you already know that vitamins are good for you, but this one helps reduce dryness and flakes.

What if my main concern is my lengths—how will the Pre-Shampoo Mask help?

If your strands could use some deep conditioning and repair, this is where your Lengths Mask comes in. Used once a week to once every two weeks, it can contain ultra-hydrating ingredients like our Nutrition complex—a mix of Argan, Sacha Yushi and Jojoba Oils that restores damaged hair. These oils may be too heavy-duty for certain shampoo and conditioner formulas, but used in a mask, they’ll leave your strands softer and more manageable.

And since your Lengths Mask will be customized to your needs, it may contain additional ingredients for color protection, curl definition, and more. But each and every Lengths Mask will contain natural moisturizers like Mango Butter to fortify strands and smooth split ends, and Glycerin to lock in moisture and protect from heat damage.

How do I use my Pre-Shampoo Mask?

Every mask order arrives with a leaflet containing how-to instructions, along with details on how often and how long you should leave in your mask. But as the name indicates, your Pre-Shampoo Mask should always be used on damp hair and followed by shampoo.

Received a Lengths Mask? Warm it in your palms and saturate your lengths, avoiding the roots. A little heat also helps the product penetrate, so you can apply your mask then heat your strands with a hair steamer or a hot towel.

Now here’s where we might get into foreign territory: the Scalp Mask. But there’s no need to be intimidated! For a quick step-by-step video from The Pros, just click the link here. Be sure to avoid your lengths and massage the product onto your scalp, section by section. Go ahead, give yourself the full salon treatment—your scalp (and your stress levels) will thank you.

Can I leave in my Pre-Shampoo Mask overnight?

If you just read the above and thought “I bet this would work even better overnight,” you’re not alone. The Pre-Shampoo Mask is a luxurious cream, formulated with your chosen Prose fragrance—why wouldn’t you want to leave it on a bit longer? But while it may be tempting to sleep in your mask, 5-30 minutes (depending on your unique routine) is all you need.

Unlike our Custom Leave-in Conditioner, your mask is meant to be fully rinsed off after use, leaving your strands or scalp feeling healthy but never weighed down. It also sets the stage for your shampoo and conditioner to work even more effectively, ensuring that you get the most out of each wash.

  1. Well mine came with the wrong instructions and pouring all out of the top – so it says lengths but clearly I indicated my hair is super oily on top and more dry on ends. This has left me more confused than happy!

  2. All of my instruction leaflets had their ink smeared and nothing was legible. How So i KNOW-HOW to use My PRODUCTS?

  3. After using the mask, do i then wash and cond my hair. I lost the instructions when i received My products.
    Thank you

    1. Yes! After you use your Pre-Shampoo Hair Mask, you should cleanse and condition your hair as usual 🙂

    1. Hi Catrina, we’re so sorry you didn’t receive instructions for your mask! Are you using the scalp or hair mask?

      -Keely, Prose Community Manager

  4. Hello! So after I rinse the mask out, I only shampoo my hair and then dry/style? I do not use conditioner after shampoo? Would love to make sure I’m doing it right as it’s not totally clear on the instructions. Thank you!

    1. Hi Maria, we still recommend using a conditioner after cleansing your hair in addition to the Pre-Shampoo Hair Mask.

    1. Hi there, yes! You can totally use your custom Pre-Shampoo Scalp Mask more than twice a week 🙂

      -Keely, Prose Community Manager

    1. Yes! It is formulated to be used before cleansing so it’s fine if your hair is dirty 🙂

  5. I saw a comment saying it’s okay to use the mask on dirty hair-does this means it’s okay to use on my scalp that I’ve applied dry shampoo to maybe 3 days in a row already? Should I wash once, then use the mask and wash against after?

    Thank you!

    1. Hi there! Our Pre-Shampoo Scalp Mask is formulated to be used before you cleanse your hair so it’s fine if you still have product left in your hair 🙂

  6. It would be helpful if there were online instructions for the at length hair mask. My instructions were accidentally thrown away in a mad cleaning frenzy and I don’t remember the length of time it said to leave it in before shampooing and conditioning.

    1. Hi there! We recommend leaving your Pre-Shampoo Hair Mask in for 15 minutes prior to cleansing 🙂

      -Keely, Prose Community Manager

  7. I didn’t get any leaflet or any instructions on how any of your products are supposed to be used.. very disappointed about that but super excited to figure it out!

    1. Hi Laurie, we are so sorry to hear that! Please contact us at and we will send over a copy of your product info! 🙂

  8. I am sorry but I can’t find my leaflet – how do I know how to use my unique pre-shampoo mask? Thank you.

  9. I did not receive instructions with my hair mask.

    I’ve read to apply to dry hair and I’ve read apply to damp hair.

    I prefer to use it on dry hair.

    Is this ok?

    1. Hi Marie! We recommend applying your Pre-Shampoo Hair Mask to wet or damp hair and leaving on for 15-20 before cleansing. We do recommend applying to damp or wet hair to ensure the hair cuticle is able to absorb the nutrients of the mask.

  10. What do I do if this statement is false? “Every mask order arrives with a leaflet containing how-to instructions, along with details on how often and how long you should leave in your mask.”

    1. We’re sorry you didn’t get your instruction leaflet in your box! Please email us at and we can resend it to you via email 🙂

    1. Hi! It all comes down to what your hair needs and goals are. Our Pre-Shampoo Hair Mask can add hydration, strengthen damaged strands, add shine, and much more. While you will see results from the Shampoo and Conditioner, the Hair Mask can also make a huge difference in the look and health of your hair.

  11. I just started using Prose and so far so good. However the one thing I would note, for the price, the bottles should at least include pumps. The cap is awkward in the shower and can dump out too much shampoo. You may want to think about this addition. Thank you.

    1. Hi Nicole! All of your orders should arrive with pumps unless you opted out of getting them (they’re located under the bottles in the box!) If you’re missing them, please send us an email at and we’d be happy to replace them for you.
