IGK GOOD BEHAVIOR 4-in-1 Prep Spray | Leave In + Detangle + Heat Protectant | Vegan + Cruelty Free |

I’ve been using IGK Good Behavior 4-in-1 Prep Spray for a few weeks on damp hair before blow-drying, and it’s become part of my regular routine. It detangles easily, helps control frizz, and leaves my hair noticeably smoother after heat styling. The spray is lightweight and distributes evenly without making my hair feel greasy or heavy. I like that it combines leave-in conditioning, detangling, and heat protection in one step, which cuts down on the number of products I need. My hair looks polished and soft with a healthy shine, not flat or stiff. The scent is clean and subtle, and the vegan, cruelty-free formula is a bonus. For very dry ends, you may still want an oil, but for everyday prep and heat styling, this works really well. Overall, it’s an effective all-in-one spray that delivers on its claims, and I would repurchase.

I love it! It detangles my hair easily, controls frizz all day, protects from heat, and gives it a beautiful shine. My hair feels so much softer and more manageable after using it, and I've noticed that my hairstyle lasts longer without frizz, even on humid days. The texture is lightweight. I'll definitely buy it in a larger size.

I've been using the IGK Good Behavior 4-in-1 Prep Spray for several months now, and it's been a game-changer for my hair routine. My hair is fine, thin, and tends to get oily, so I'm always cautious about using products that might weigh it down. This spray, however, is lightweight and doesn't leave any residue, making it perfect for my hair type. What I Love: Frizz Control: Keeps my hair smooth and manageable, even on humid days. Heat Protection: Provides excellent protection when I use heat styling tools, reducing damage and keeping my hair healthy. Detangling: Makes combing through wet hair effortless, with noticeably less breakage. Shine and Softness: Adds a healthy-looking shine and softness without making my hair feel greasy or heavy. Scent: The coconut scent is pleasant and not overpowering, adding a fresh touch to my hair. Application: I apply it to damp hair before blow-drying, and it distributes evenly without any residue. Size: The 7 oz bottle is generously sized and lasts a long time, even with regular use. Overall, this product delivers on its promises. It's a bit on the pricier side, but considering the results and the fact that a little goes a long way, it's worth every penny.

This spray is the absolute best! I use this after I wash my hair in lieu of any gels/mousse. It makes your hair soft and not sticky or greasy. My hair has gotten so much healthier over the last year of using it! It's a little pricey, but worth it!

It is doing exactly what it promises, but I think the price is too high for the quantity.

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

After two+ years of use, this prep spray remains my secret weapon for salon-worthy blowouts at home As someone in my 50s with waist-length, fine (yet thick) hair that tends to frizz and curl inconsistently, I've tried countless products promising to tame my rebellious locks. The IGK Good Behavior 4-in-1 Prep Spray has truly been a game-changer in my hair care routine. What sets this spray apart is its ability to create the perfect foundation for a professional-quality blowout. My fine strands need products that won't weigh them down, yet my inconsistent texture demands something powerful enough to smooth and unify. This spray manages to do both effortlessly. The heat protection is essential for someone like me who styles frequently, and I've noticed significantly less damage since incorporating this into my routine two years ago. Despite my length and thickness, my blowouts now look polished and stay that way much longer than with any previous product. I sleep with a silk cap at night, and my blowouts last a week. The spray distributes evenly without creating product buildup or leaving my hair feeling stiff or sticky. As you are blow drying, it does have a slight stickiness on your hands, but it's more like a lotion. The ingredients are amazing. It controls frizz remarkably well, even in humid conditions, while still allowing my hair to move naturally. If you're struggling with aging hair that seems to have developed a mind of its own, this prep spray might be exactly what you need. It's become an absolute essential in my routine and delivers salon-quality results consistently. Worth every penny!

Not sure if this really works and it does not smell good.
