## Description

A multi-tasking, IGK Good Behavior hair prep spray that detangles, protects against heat, controls frizz, enhances shine.

Review: One Product That Does It All! ⭐⭐⭐⭐⭐ - This has become one of those hair products I never want to be without. It does everything I need in one bottle—detangles, protects my hair from heat, helps smooth frizz, and leaves my hair feeling incredibly soft. I use it before blow-drying or styling, and it makes such a difference. My brush glides through my hair with much less tugging, and my hair looks smoother, shinier, and healthier without feeling weighed down or greasy. It also smells amazing, which is always a bonus! A little goes a long way, and I love knowing my hair is protected before using hot tools. If you're looking for a leave-in product that simplifies your routine while keeping your hair soft, manageable, and protected, I highly recommend this one. It's definitely earned a permanent spot in my hair care routine.
Review: Great! - I recently tried the IGK GOOD BEHAVIOR 4-in-1 Prep Spray and here are my thoughts: From the moment I sprayed it on towel-damp hair, I could tell the product was lightweight and non-gummy. It has a fresh, clean scent that doesn’t overpower. As a leave-in formula, it managed to smooth my hair quite nicely—my usual frizz and flyaways calmed down significantly after using it. Detangling was much easier: the spray gave enough slip that I didn’t feel like I was tugging through knots. When I applied heat tools (blow-dryer + flat iron), I felt confident that the “heat protectant” claim had substance — my hair looked shiny and smooth afterward, without that dull or brittle feel I sometimes get. On the flip side: if your hair is extremely coarse or very long, you might need to use more than the suggested amount. Also, while it helps manage frizz and detangling, it’s not a deep-conditioning treatment — you’ll still want a good mask or conditioner in your routine for heavy repair. Overall, I’m impressed with how multi-functional this spray is. If you’re looking for a time-saving step that covers multiple bases—leave-in treatment, detangler, heat protectant—with ethical credentials, this one is definitely worth a try. I’ll likely keep it in my rotation

## Questions & Answers

**Q: Is it non toxic?**
A: Upon researching all ingredients I found this product to be non toxic.

**Q: Customer:  can I use other products in my damp hair after using the Expensive Gloss?  Will it affect what the gloss does after you used in in your sho**
A: As a brand representative for IGK, I will be happy to answer your question! Expensive is meant to be used in place of conditioner 1-2x per week and rinsed from the hair before styling with your favorite products. As long as your preferred products are not mattifying, they should not dull the shine from Expensive. I hope this helps!

**Q: Most prep sprays for me end up making my hair look dull. Does this do that?**
A: It does keep my flyaways down but dull? Not super shiny but not dull either… if your looking for high shine this may not do it….

**Q: What are the ingredients? Does it build up in your hair?**
A: No build up. To my hair
