Good Behavior 4-in-1 Prep Spray, Heat Protectant, Leave-In Detangler | Controls Frizz for 24 Hours, Heat Protection + Shine, Weightless + Vegan, 7 Oz

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.

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

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 genuinely have never used a better product. It makes me hair smooth and cooperative without being greasy AT ALL. I have that kind of hair that’s straight and fine and dries kinda wavy in places and is very porous - this spray makes it silky and manageable. If I blow dry my hair with this spray in it (plenty of pumps) and sleep with a silk bonnet on, my hair loons great for 4 days between washes. Love it so much. A bottle lasts a long time too! The pic is my hair just with the spray and blow dried, no straightening! Edited to add, although it’s pricey, a bottle lasts me 5-6 months. I have really long hair and spray it liberally! Although I will say only wash my hair every 4 days, in between I shower with a shower cap.

⭐⭐⭐⭐ The IGK GOOD BEHAVIOR 4-in-1 Prep Spray is a versatile and multi-use product that I had high hopes for, and while it delivered satisfactory results, I must admit I was expecting a bit more. On the positive side, the leave-in, detangling, and heat protectant properties are convenient and make it a time-saving addition to my hair care routine. I appreciate the lightweight feel and the fact that it doesn't weigh down my hair or leave any residue. The heat protection is crucial, especially for someone who styles their hair frequently. However, I was hoping for a bit more noticeable improvement in the overall health and manageability of my hair. While it did help with detangling, I didn't experience a significant difference in terms of added shine or enhanced smoothness. I have used other products that seemed to provide a more transformative effect. The fragrance is pleasant, not overpowering, which is a plus. The packaging is sleek and user-friendly. In summary, the IGK GOOD BEHAVIOR 4-in-1 Prep Spray is a decent product that fulfills its promises to some extent. It's a practical choice for those looking for a multi-use spray, but if you're expecting a dramatic transformation, it might fall slightly short of those expectations. Four stars for its convenience and functionality, but a small deduction for not achieving the level of improvement I had hoped for. ⭐⭐⭐⭐

Does what it says! Hair is not as noticeably soft as when I use money mist after washing, but I’ve noticed my style lasts a day longer between washes without getting greasy and feels great. Will purchase again. Was using Money Mist combined with Kenra blow dry spray. I replaced both of those with this one product and happy with the results.

I don’t love all IGK product, some are too heavy for my fine hair. And living in Florida heavy products make your freshly washed hair look greasy within a day. However this product is amazing, I spray evenly throughout my hair after the shower and it helps me detangle my knotted thin hair lol It also doubles as a heat protector It’s sort of expensive but the bottle does last me for a few months and I use it everyday, so it’s a good size. The product smells nice It does nothing to curl my hair but it does leave it feel more moisturizing.

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.

It works so well

Was a bit skeptical about this product but it works great for the first 48hrs, soft hair no frizz

Works well. Don’t love the scent, but it’s not bad. Does not make my hair crunchy or stiff. Helps hold waves or curls from wet hair.
