IGK Good Behavior Anti-Frizz Smoothing Serum 1.3 oz — Instant Glass-Like Shine & Humidity Protection

IGK Good Behavior Anti-Frizz Smoothing Serum is a concentrated finishing serum that smooths frizz, locks out humidity, and adds mirror-like shine for dry, frizz-prone hair.

Designed as a finishing step for medium to coarse hair, this 1.3 oz serum blends botanical oils and Shine Seal Technology to create a water-resistant, high-gloss surface. Lightweight but concentrated, it helps tame flyaways and protects hair from heat and UV exposure while leaving a polished, salon-ready finish. The formula is free from sulfates, parabens, phthalates, gluten, mineral oil, and petrolatum.

How quickly will I see smoother, shinier hair?

Results are immediate on application: hair appears sleeker and reflects more light right after you smooth a small amount through dry or damp strands. Continued use maintains the sealed, glossy look while helping control frizz for multiple days in typical conditions.

• Instant glass-like shine on first use
• Formulated to boost shine by up to 75%
• Creates a reflective, liquid-like surface with botanical oils

Can this serum stand up to humidity and daily styling?

Shine Seal Technology forms a water-resistant barrier that helps repel humidity and tame frizz for up to four days under normal environmental exposure. It’s intended as a finishing product to lock styles in place and reduce the need for repeated touch-ups.

• 4-day frizz control claim when used as directed
• Water-resistant seal helps keep flyaways down in humid conditions
• Suitable for sealing blowouts, straightening, or smoothing styles

What ingredients give it shine and protection?

The serum combines nutrient-rich botanical oils—coconut, chia, and cherry seed—for hydration and high-gloss reflectivity. In addition to these oils, the formula includes components that provide UV and heat protection, helping protect hair from styling tools and sun exposure.

• Coconut, chia, and cherry seed oils for moisture and reflective shine
• UV protection to help reduce sun-related color and texture changes
• Heat-protectant properties to support styling with tools

How much should I use and how do I apply it?

Because the serum is concentrated, a little goes a long way—start with a pea-sized amount and increase as needed for length or thickness. Rub between palms, then smooth through mid-lengths and ends; use sparingly at roots to avoid weighing hair down.

• Apply to damp or dry hair as the finishing step
• Distribute from mid-shaft to ends; avoid the scalp for lightness
• Use more on coarse or longer hair, less on fine textures

Who is this for: IGK Good Behavior Anti-Frizz Smoothing Serum is formulated for people with dry, frizz-prone, medium to coarse hair who want a high-shine, sealed finish and protection from humidity, heat, and UV exposure.

If you prefer concentrated, botanical-oil-based finishes and need lasting control in humid environments, this serum is a targeted option to add to your styling routine.
