MONDAY HAIRCARE SMOOTH Heat Protectant Spray — Pack of 2 6 oz, Keratin-Infused Lightweight Shield up to 450°F

If you style with blow dryers, flat irons, or curling wands, protecting strands against high temperatures and friction matters. MONDAY HAIRCARE SMOOTH pairs heat defense and keratin reinforcement in a non-sticky mist that helps reduce breakage, control flyaways, and preserve shine without weighing hair down. The formula is pH-balanced, dermatologically tested, sulfate- and paraben-free, and certified cruelty-free.

How does SMOOTH protect hair from high heat?

SMOOTH forms an invisible protective barrier on the hair shaft to reduce direct thermal damage and friction from hot tools. It’s engineered to withstand temperatures up to 450°F/230°C so styling tools can work with less stress on the fiber.

• Protects against temperatures up to 450°F/230°C
• Creates a lightweight shield to reduce tool friction
• Helps lock in moisture to reduce heat-related dryness

What role does keratin play in this spray?

The formula includes keratin, a protein that helps smooth the cuticle and visibly reduce frizz and split ends. Keratin’s conditioning action supports strand strength, making hair feel softer and appear glossier after styling.

• Keratin-infused to smooth cuticles and tame flyaways
• Helps reduce the appearance of split ends and breakage
• Enhances shine and manageability for polished results

Will SMOOTH weigh my hair down or leave residue?

SMOOTH is formulated to be lightweight and non-sticky so it won’t leave a heavy coating or visible buildup. It sprays on evenly and rinses out, leaving hair soft to the touch while preserving natural movement and volume.

• Non-sticky mist applies evenly to damp or dry hair
• Lightweight finish maintains volume and natural movement
• Dermatologically tested and pH-balanced for everyday use

Is this product suitable for all hair types and routines?

SMOOTH is designed to work with a wide range of textures, from fine to thick and frizz-prone hair. Whether you’re blow-drying for smoothness, flat-ironing for a sleek look, or curling, the spray supports better styling outcomes while respecting fragile or color-treated strands.

• Safe for fine, medium, coarse, and frizzy hair types
• Compatible with heat styling, blow-drying, and chemical services
• Free from sulfates and parabens; PETA- and Leaping Bunny-certified

Who is this for: MONDAY HAIRCARE SMOOTH Heat Protectant is ideal for anyone who heat-styles regularly and wants a reliable, lightweight barrier plus keratin smoothing benefits. It’s a good pick if you need frizz control, added shine, and protection without weight—especially helpful for people with delicate, color-treated, or frizz-prone hair seeking salon-ready results at home.
