  • No need to flat iron anymore!
Size: 5.6 Ounce (Pack of 1)
I have tried many different anti frizz products and this one by far works the best for me. I have fine naturally straight hair that is prone to frizz and needs to be blown dry. I section my hair and spray this on before drying with a flat brush and it works amazingly well! I do not need to flat iron after blow drying anymore. It does have a strong smell while applying that dissipates and is not overpowering when done styling. Hair does not feel sticky at all afterwards - feels very soft and light! ... show more

Size: 5.6 Ounce (Pack of 1)
Nice product if you are interested in a glossy shine using a flat iron. The fragrance is a bit strong. Wish it was fragrance free.

  • Can’t go without it!
Size: 5.6 Ounce (Pack of 1)
This stuff is a must have! Smells great, leaves my hair soft, shiny and frizz free. Doesn’t take a lot so it’s a good price point and I don’t use daily as it last for a few days.

  • It actually works!
Size: 2.4 Ounce (Pack of 1)
I’ve tried a lot of anti-frizz products, but GK GOOD BEHAVIOR really impressed me. It leaves my hair noticeably smoother, shinier, and more manageable without weighing it down. The spirulina protein feels like a healthy boost for my hair, and the scent is light and fresh. I also love that it offers heat protection—perfect before blow-drying or flat ironing. Definitely a new staple in my routine! ... show more

  • Update: does work in a particular way. DOES NOT WORK!!
Size: 5.6 Ounce (Pack of 1)
Update: this product does work, however, I found the trick to ot is to wash your hair and while it is still wet spray this product in and blow dry with brush or air brush. I have curls and it will take out all your curls but it will keep your hair from frizzing and give it a nice shine if you put it on while your hair is wet, not damp. Flattens, straightens, makes it crunchy NOT SOFT, the scent is HORRIBLY OVERWHELMING, does not make it Shiney, and does not take the frizz out ... show more

  • Honest review
Size: 2.4 Ounce (Pack of 1)
I preface this with the fact that I have naturally curly hair that is coarse and thick. (Picture 1 is of my hair on a “normal” day. ) I read several complaints about fragrance. It does have a fragrance. I can see how some may not like it. I’m fine with it. Has an underlying black pepper scent. I Don’t find it unpleasant. It’s an aerosol so, yup, spray and hold your breath like you would hairspray. It’s a “protein” spray so I did expect it to make my hair feel a little stiff I used it exactly as recommended. I did pair it with the IGK Expensive Clear Gloss Too Coat in the shower. My hair dried in 50% of the time it normally takes so that is a plus. I used a brush blowdryer. I think it did what it is suppose to do. Why it gets 3 stars is that the claims it makes are unrealistic. I cannot just walk out the door after blowdrying. It’s a frizzy mess. (Picture 2) (Although better than what it would be without it ) I will still need to flat iron it. I’m in my late 50’s and have tried virtually every product imaginable in my 59 years I think it earns 3 stars. It’s an average product with unreasonable claims for me. 3rd picture is after flat iron and no other products used on it yet. I typically use a moroccan oil after ... show more

  • One of the best hair products I’ve used
Size: 5.6 Ounce (Pack of 1)
Love this hair product! I was excited when I was able to find it on Amazon. This works great when I flat iron my hair. It instantly makes it smooth and shiny. I highly recommend this product if you want something to help smooth frizz and add shine when straightening your hair.

  • Very strong perfume smell
Size: 5.6 Ounce (Pack of 1)
This works very well, but it has such a strong perfume smell I can’t stand smelling it all day. If it wasn’t for that I would have given 5 stars
