Leave-In Conditioner tip #471

For an extra dose of hydration, use Prose custom leave-in conditioner alongside custom hair oil. Apply your leave-in on damp or dry hair, then finish with hair oil to lock in moisture without any greasy residue.

Frequently asked questions

Prose leave-in conditioner is custom-formulated for every individual, and isn't limited to one hair type. It delivers the right amount of hydration for your needs, and contains a unique blend of active ingredients to meet your hair goals.


Custom leave-in conditioner can be applied on damp hair as a hydrating mist and styling primer. It can also be used on damp, towel-dried hair as a detangler before or after washing. More instructions and a fully detailed routine will come with your unique formula. Custom Leave-in can also be used as a heat protectant before heat styling—it’s lab-proven to protect strands up to 450°F. In the consultation, we’ll ask about your styling routine; be sure to select whichever heat tools you use, and your custom formula will be thermoprotective.


Our non-greasy formula keeps strands hydrated and soft without feeling weighed down. And since it's meant to be left in until your next wash, you can rest easy—it leaves no trace on your pillowcase or sheets.


Yes—all Prose products are color-safe, and if you indicate color treatments during the consultation, your custom leave-in may contain additional ingredients for color protection.


There's no need to worry—all leave-in conditioner formulas are vegan. Additionally, you can opt for a silicone-free and/or fragrance-free formula during the consultation.


Prose custom leave-in conditioner is free from the following: alcohol, phthalates, GMOs, sulfates, parabens, phthalates, and mineral oil. Like all Prose products, leave-in conditioner is cruelty-free.


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.
