How does this spray protect hair during heat styling?

IGK Good Behavior forms a protective barrier that helps minimize direct heat exposure from blow dryers, flat irons, and curling wands. It’s engineered to resist temperatures up to 450°F, reducing the visible signs of heat stress while supporting smoother styling results.

• Heat protection rated to 450°F for high-temperature tools
• Lightweight polymer film that reduces direct heat contact
• Non-greasy finish so hair remains touchably soft

Will this help control frizz in humid conditions?

The formula targets frizz for up to four days by smoothing the hair cuticle and resisting humidity-driven puffiness. Regular use can keep flyaways in check and extend the life of a sleek blowout between washes.

• 4-day frizz-fighting performance for prolonged smoothness
• Humidity-resistant polymers reduce puffiness and flyaways
• Ideal for maintaining sleek styles through changing weather

Can it improve hair strength and manageability?

Infused with spirulina protein and a bonding polymer, the spray helps reinforce hair structure while smoothing the surface, which makes styling easier and reduces breakage during hot-tool use. Over time, this supportive care can make hair feel stronger and more manageable.

• Spirulina protein supports strand reinforcement and resilience
• Bonding polymer mimics keratin treatment effects without chemical processing
• Weightless conditioning reduces tangles and improves comb-through

How do I use IGK Good Behavior in my routine?

Use on towel-dried hair before blow-drying or on dry hair before flat-ironing or curling. Spray evenly from root to ends, comb through for distribution, then style with tools as desired for best results.

• Apply to damp hair prior to blow-drying for smoother results
• Use on dry hair before straightening or curling for added protection
• Reapply lightly for mid-day touch-ups on frizz-prone areas
