IGK Good Behavior Smoothing Spray 11 oz — Heat Protectant up to 450°F, 4-Day Frizz Control for Sleek, Shiny Hair

IGK Good Behavior Smoothing Spray is a lightweight, heat-activated styling mist that delivers up to four days of frizz control while protecting hair up to 450°F for a keratin-like, glossy finish.

This jumbo 11 oz bottle brings salon-style smoothing to your daily routine with a weightless formula that tames flyaways, shields strands from high heat, and leaves hair looking polished without buildup. Formulated with spirulina protein and a bonding polymer, the spray helps fortify the hair shaft and mimic the smoothing effect of a keratin treatment—without harsh chemicals or downtime. It’s vegan, cruelty-free, and safe for color-treated hair, making it a versatile option for a wide range of styling needs.

How does IGK Good Behavior help protect hair during heat styling?

The formula creates a protective layer that resists temperatures up to 450°F, reducing the immediate risk of heat damage from flat irons, curling wands, and blow dryers. Because it’s heat-activated, the smoothing and shine effects intensify as you style, giving a glass-like finish with consistent protection.

• Heat protection up to 450°F to minimize thermal stress
• Activates with heat for enhanced smoothing and gloss
• Lightweight layer that doesn’t weigh down styles

Will this product actually reduce frizz for multiple days?

Good Behavior’s anti-frizz system is designed to lock down flyaways and resist humidity, offering up to four days of improved smoothness depending on your hair type and environmental factors. Reapplication or touch-ups can extend control between washes, especially in humid conditions or with naturally frizz-prone textures.

• Formula designed for up to four days of frizz reduction
• Humidity-resistant polymers help maintain smoothness
• Suitable for reapplication without buildup

Can I use this on damp and dry hair, and does it work on all textures?

You can spray Good Behavior on damp hair before blow-drying for a sleek base or mist over dry hair prior to heat styling for targeted smoothing. The lightweight finish works across straight, wavy, curly, and coily hair to reduce flyaways, boost shine, and improve manageability without feeling greasy.

• Use on damp hair for full blow-dry smoothing
• Apply to dry hair for spot-control and added shine
• Effective on straight, wavy, curly, and coily textures

What nourishing ingredients help strengthen hair?

IGK blends spirulina protein with a bonding polymer to reinforce the hair’s structure and help reduce breakage while creating a smooth surface. These components mimic some benefits of a keratin service—improving slip and shine—without formaldehyde or salon recovery time.

• Spirulina protein supports structural strength and resilience
• Bonding polymer smooths the cuticle for improved gloss
• Vegan, sulfate- and paraben-free to protect color and integrity

Who is this for? IGK Good Behavior Smoothing Spray is ideal for anyone who regularly uses heat tools and wants long-lasting frizz control with high-heat protection—particularly people seeking a lightweight, salon-grade finish without harsh chemicals. It’s a practical pick for those with color-treated hair, multi-textured households, or anyone wanting a quick route to sleek, shiny styles at home.
