IGK Good Behavior Anti-Frizz Smoothing Serum 1.3 oz — Lightweight Shine, Humidity & Heat Protection

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

This lightweight, moisture-rich serum blends coconut, chia and cherry seed oils with IGK's Shine Seal Technology to create a water-resistant barrier that helps keep hair smooth and glossy. The formula is designed to tame flyaways, improve manageability and add a reflective finish without weighing hair down. It provides heat and UV protection while avoiding sulfates, parabens, phthalates, gluten, mineral oil and petrolatum.

How does this serum control frizz through humidity?

The Shine Seal Technology forms a thin, water-resistant layer around each strand to reduce moisture absorption from the air, which helps prevent frizz from returning. This seal is tuned to resist common humidity levels so styles remain smoother for days.

• Creates a moisture-blocking finish that reduces frizz for up to four days
• Water-resistant barrier limits humidity-driven swelling of the hair cuticle
• Leaves hair soft and touchable, not stiff or crunchy

Will this serum add shine without weighing hair down?

The concentrated botanical oils in the formula—coconut, chia and cherry seed—are selected for high-reflective payoff while remaining lightweight. Applied sparingly to mid-lengths and ends, the serum creates a liquid-like gloss without making medium to coarse hair greasy.

• Delivers up to 75% more visible shine when used as a finishing product
• Concentrated formula means a little goes a long way for long-lasting results
• Leaves hair with a polished, glassy appearance ideal for finished styles

How should I use it with heat styling and sun exposure?

Use a small amount before blow-drying or flat-ironing to help protect strands from thermal stress and UV exposure. The serum provides an added protective layer that helps reduce dryness and surface damage from styling tools and sunlight.

• Apply a pea-sized amount to damp hair, focusing on mid-lengths and ends
• Comb through, then blow-dry or style as usual for best sealing and shine
• Touch up on dry hair to tame flyaways and boost gloss between washes

Is this product safe for chemically treated or textured hair?

The formula is formulated without common harsh ingredients and is suitable for dry, frizz-prone textures, including chemically treated, color-treated and textured hair. Its nutrient-dense oils help restore surface moisture and improve combability without adding heavy build-up when used correctly.

• Free from sulfates, parabens, phthalates, gluten, mineral oil and petrolatum
• Concentrated oil blend supports moisture balance in medium to coarse strands
• Works well on color-treated hair when used as a finishing step

Who is this for: IGK Good Behavior Anti-Frizz Smoothing Serum is aimed at anyone with dry, frizz-prone hair who wants a salon-finish shine and longer-lasting smoothness. It’s especially useful for medium to coarse textures, people who live in humid climates, and those who finish styles with heat tools or seek extra UV protection for their hair. Use it sparingly as a finishing step or as a protective boost before heat styling to achieve sleek, reflective hair without heavy residue.
