If you regularly use blow dryers, flat irons, or curling wands, this dual-pack of 6 oz SMOOTH Heat Protectant offers a reliable barrier between heat and your hair.

How does this heat protectant defend hair during styling?

The spray creates an invisible thermal shield that helps reduce the direct impact of hot tools, minimizing friction and moisture loss. It’s rated to protect up to 450°F/230°C and builds a lightweight coating so you can style at higher temps with greater confidence.

• Protects hair from temperatures up to 450°F/230°C
• Forms an invisible barrier against tool friction
• Locks in hydration without adding weight

What role does keratin play in the formula?

Keratin in the formula supports the hair’s structural integrity by smoothing cuticle edges and reducing the appearance of split ends. It helps strands look sleeker and more uniform while lowering the chance of breakage during heat styling.

• Strengthening protein to help smooth frizz and split ends
• Improves manageability and shine
• Supports healthier-looking hair with regular use

Will this weigh down fine hair or leave a sticky residue?

The SMOOTH spray is formulated to be lightweight and non-sticky, so it won’t flatten fine hair or leave tacky buildup. It distributes evenly and absorbs quickly, allowing styling tools and products to perform as expected.

• Non-sticky finish suitable for fine and flat-prone hair
• Lightweight delivery for even coverage
• Compatible with other styling products

Is this product safe and ethically made?

The spray is free from sulfates and parabens, pH-balanced, and has been dermatologically tested for everyday styling use. It carries cruelty-free certifications and is PETA- and Leaping Bunny–approved.

• Sulfate- and paraben-free formulation
• PETA and Leaping Bunny cruelty-free certifications

It suits fine, thick, curly, or chemically-treated hair and is a practical pick for daily stylers, busy professionals, and salon-styled looks at home. If you value a product that combines protection, shine, and ethical credentials in an easy-to-spray format, this keratin-infused protectant was designed with you in mind.
