IGK Good Behavior Anti‑Frizz Smoothing Serum, 1.3 oz — Lightweight Shine & Humidity Protection for Dry, Frizz‑Prone Hair

IGK Good Behavior Anti-Frizz Smoothing Serum is a concentrated finishing serum that seals out humidity, boosts shine, and tames frizz for dry, frizz-prone hair.

Designed as a finishing step for medium to coarse, dry hair, this 1.3 oz serum delivers glass-like shine and long-lasting frizz control without weighing hair down. Its nutrient-dense blend of coconut, chia and cherry seed oils smooths cuticles and imparts a reflective, polished finish while Shine Seal Technology forms a water-resistant barrier to lock out humidity. Lightweight UV protection and a sulfate-/paraben-free formula make it a simple add-on to any styling routine.

How quickly will I see smoother, shinier hair?

Results are immediate upon application: the serum smooths flyaways and creates a mirror-like surface, visibly increasing shine. Continued use preserves the finished look and helps hair appear sleeker through humid conditions.

• Instant glass-like shine on damp or dry hair
• Noticeable smoothing after the first application
• Formula boosts shine by up to 75%

How does Shine Seal Technology protect against humidity and heat?

Shine Seal Technology forms a light, water-resistant seal around the hair shaft that helps prevent moisture from causing frizz. The serum also includes heat- and UV-protective components to defend styled hair from environmental stressors.

• Creates a water-resistant barrier to repel humidity
• Helps maintain styles for up to four days under typical conditions
• Provides UV protection to reduce environmental damage

How should I use this serum for best results?

Apply a small amount to mid-lengths and ends of towel-dried or dry hair, focusing on areas with frizz or flyaways. Start with a pea-sized amount and add more only if needed to avoid buildup; it’s formulated as a concentrated finisher rather than a daily moisturizer.

• Use on damp hair before blow-drying for a sleek finish
• Add to dry hair as a finishing touch to tame flyaways and boost shine
• Work through with fingers or a wide-tooth comb for even distribution
