Flouf Factor Growth™ Leave-In Mask

Either! Apply a small amount to dry ends, add a larger amount combed through wet hairto use as a styling product for a slicked-back look, or 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.

Yes! The FGF5 inhibiting 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.

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

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, aging, 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.

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

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 cosmetic products 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 caution—not because of any known risk. 

Out of an abundance of caution and as some pregnant individuals may choose to avoid fragrance allergens during their pregnancy, 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.

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.
