Thicker, more voluminous hair in 60 seconds! This perfect hair thickening and volumizing spray gives you light, airy volume and all-day flexible hold. It amps up thin or fine hair, making it appear thicker, fuller, and healthier with mega volume and body. Hair feels touchable and natural, never crunchy or greasy.

Unique non-sticky formula: Our super lightweight formula won't leave sticky residue or buildup like mousse or sea salt spray, which means it won't weigh down your delicate strands! A hair texturizing spray + volume spray without the gunky residue, this natural hair thickener + texturizer washes out cleanly & easily. It’s the perfect hair thickening solution for women and men. Recommended for medium to oily hair of all lengths and colors (including color-treated hair).

Gorgeous matte finish: Say “goodbye” to grease and “hello” to head-turning volume and texture! Simply apply lightly and evenly to lengths of damp hair, comb or tousle through, and dry/style as usual for enhanced thickness and instant volume.

Light hold and manageability: Perfect for use as a pre-styler, our ultimate hair thickening + volumizing spray provides light hold, natural definition, and extra “grip” for easy styling. Add texture, volume and hold to your braids and upstyles (even if you have ultra-sleek, silky hair) by prepping your hair with Thickening Spray. This premium hairspray is often called the “professional stylist’s secret weapon” for achieving salon-level styles!

Natural hair-boosting ingredients: Packed with minerals and nutrients, our thickening spray's ability to absorb excess oil and moisture makes it one of the best volumizing hair sprays for women & men! Rather than harsh chemicals, Boldify Hair Thickening Spray uses gentle, effective body boosters like algae extract, epsom salt and giant sea kelp to nourish and thicken hair naturally. The result is healthy, natural volume and hair that looks (and feels!) amazing.

Made responsibly in the USA, results guaranteed - Boldify hair styling products are proudly made in the USA under GMP guidelines, without harmful chemicals like parabens, and never tested on animals - 100% cruelty-free. You can rest assured you'll see thicker hair and a fuller finish from this pure, potent, safe hair thickener for men and women - or we'll refund you the purchase price.

    Volume and Hold Without Stickyness

    I have very fine hair and have had a hard time finding a product that gives me the volume and hold that I want. After using Boldify just a few times so far, I'm happy with the results. My hair, especially the roots, has more volume and hold when I use this product.
