Flouf Factor Growth™ Leave-In Mask

Flouf Factor Growth™ Leave-In Mask

NO-RINSE FORMULA LEAVES STRANDS GLOSSY AND SILK-SOFT ENRICHED WITH BAOBAB

DESCRIPTION

STRENGTHENS STRANDS, VISIBLY THICKENS AND SUPPORTS HAIR GROWTH.

A once-in-a-while leave-in hair treatment that takes two seconds to do with visible results that last ages: improved elasticity, tamed frizz and flyaways, increased shine, and silky soft strands.

With regular use, hair is noticeably thicker, healthier and shinier looking. Tick tick tick!

Size: 150mL

HOW TO USE

This hair mask is about as low-maintenance as it gets.

Apply a generous amount to the ends of washed, towel-dried hair and comb through with fingers or a wide-tooth comb. That's literally it.

WHY YOU'LL LOVE OUR LEAVE-IN HAIR MASK

For a leave-in hair treatment that not only smells good but also leaves hair shiny and hydrated, you'll love the Flouf Factor Growth™ Leave-In Mask. It's an ally to hair health and perfect for styling that slick back look, without being too heavy or buttery. 

This simple hair treatment gives fine patchy hair a fuller look, especially when used with the rest of our Flouf Factor Growth™ range. And with all that new growth popping through, who knows what else is possible (hello lucky girl syndrome)!

WHO IT'S FOR

Unlike other hair masks, ours is powered by effective hair tech that's engineered for most hair types. If you have thinning hair or are experiencing postpartum hair loss, it's just the kind of stress-free hair treatment you may need. 

Apply, comb through and leave in – then wait for the magic to happen.

FLOUF FACTOR GROWTH™

FGF5 is a protein that tells your hair when it’s time to stop growing and fall out. Think of it like a timer – when it goes off too soon, it shortens the hair’s growth phase. This can lead to thinner, weaker hair or more shedding. Managing FGF5 helps keep that timer from going off too early, so your hair has more time to grow thick and strong. Think of our FGF5 hair tech as the snooze button.

No sulfates, phosphates, silicone or phthalates.

Bouf's hair mask is formulated with 100% natural actives.

Colour safe, keratin safe and extension safe.

FAQ's

The answers to your ‘wait, what?’ moments

What does a hair mask do?

A hair mask is one of those hair treatments that often feels bougie, but isn’t. Why? It uses time and deep-conditioning to restore moisture, boost hair shine and softness, tackle frizz, and repair the damage caused by heat, coloured dyes and/or bleach. 

Are hair masks good for your hair?

They can be... if you choose the right one for your hair type and #hairgoals. A hair repair mask like Bouf's leave-in hair cream is a fabulous option to turn up your hair's volume and improve scalp health. Especially when you use it with other Flouf Factor Growth™ products, like our Tonic, Shampoo and Conditioner.

Do I use the Flouf Factor Growth™ Leave-In Mask on wet or dry hair?

Either! Apply a small amount to dry ends or add a larger amount combed through wet hair to use as a styling product for a slicked-back look. Heck, you can even use it as a heat protectant before blow-drying or using heated tools. However, we recommend using as little heat as possible on hair to protect it from damage.

Is the Flouf Factor Growth™ Leave-In Mask suitable for all hair types?

Yes! The FGF5 technology makes it perfect for thinning hair but it is suitable for all hair types. It’s safe to use on dyed hair and hair with extensions or treated with keratin.

Do I have to leave the Flouf Factor Growth™ Leave-In Mask in?

You can leave it in all day, overnight for a more intense treatment, or wash it out after 3-10 minutes as a quicker step in your routine.

What is FGF5?

FGF5 is a naturally occurring protein in the scalp that plays a role in signalling the end of the hair growth phase. In a typical hair cycle, this is followed by a new growth phase. However, factors such as stress, hormonal changes, nutritional deficiencies, ageing, or genetics may contribute to elevated FGF5 activity, which has been associated with increased shedding and slower regrowth.

Bouf’s formula includes ingredients that have been studied for their potential to inhibit FGF5 activity. By supporting a balanced hair cycle, Bouf helps promote the appearance of healthier, fuller-looking hair over time.

Is Bouf pregnancy and breastfeeding safe?

The Bouf hair care range is formulated with ingredients that are approved for use in cosmetics. They've been tested for quality and safety, and are widely used in the industry.

Bouf products contain a light, naturally derived fragrance to give them their signature scent. While the exact blend is proprietary (as is standard for fragrance), it may include trace amounts of essential oils or other plant-based ingredients.

These are common in cosmetics and are used at very low levels. But because every pregnancy is different, our testing lab advises against making blanket claims like “pregnancy safe.” This recommendation is made out of an abundance of caution—not because of any known risk. 

We always recommend that those who are pregnant or breastfeeding consult with their healthcare provider before introducing any new topical product, even one designed with postpartum care in mind.

What types of hair fall/shedding does Bouf help?

Hair fall can occur due to various factors that affect the natural hair growth cycle, including:

  • Hormonal changes (e.g. menopause or postpartum)
  • Illness or high fever
  • Stress and lifestyle factors
  • Naturally fine or thinning hair
  • Genetic predisposition to hair thinning.

Bouf is formulated to support the appearance of thicker, fuller-looking hair and to help care for hair that may be experiencing temporary thinning. While it’s not a treatment for medical hair loss conditions, Bouf can be a supportive part of a healthy haircare routine.

    How can I give this product 10 stars?

    I received this product from a goodie bag. I’ve been using it for nearly 2 months now. Everyone, I mean EVERYONE has been asking me about my hair and how it looks so thick and lush. I didn’t even click and was quite confused on why it was actually getting better… 1000% because of using this product! My hair feels very thick, my colour has a gloss and everyone is asking me my secret. Excited to try more from bouf! ❤️

    Instant effect

    The first time I used this on my hair I knew this was something different. I applied it to my wet hair after shampooing, let it dry naturally, then I could really feel and notice a difference. My hair felt stronger immediately, more swishy, more body, not so fly-away. This is the hair product I've been waiting for.

    On fine hair you can only use a pea size amount as your hair does feel like it’s got a lot of product in when dry. Haven’t used long enough to see any benefits yet.

    Hi Amelia,

    Thanks so much for trying our Flouf Factor Growth™ Leave-In Mask and for sharing your feedback! We appreciate you letting us know about your experience with application on fine hair - it's really helpful to hear that a smaller amount works better for your hair type to avoid that heavy feeling when dry.

    We'd love to hear how you get on with it over time, and if you have any questions about the product.

    I have the most silky hair

    Look, I’ve used a lot of leave in treatments before, but never have I had one that gave me the most silky, luscious hair! I keep on glancing at my hair, it looks fake it’s that nice, smooths out my ends, looks like I have no heat damage (which I definitely do haha)
