Best Hair Product Ever !!
IGK Good Behavior Supreme Seal Anti-Frizz Serum Review This is my absolute favorite hair product — nothing else controls my frizz like this. I have naturally frizzy, unpredictable hair that usually poofs up the second I step outside, but this serum actually works. I wore it to a game in hot, humid ...

A little improvement in frizz with added shine
[I received this product in exchange for my honest review] I have very wavy hair that tends to turn to ringlets easily. I washed and conditioned my hair and let it air dry for this test. My hair does react strongly to humidity, getting curlier and frizzier where the curls are dry and unconditioned. ...

Silky, Sleek, and Weather-Proof!
[I received this product in exchange for my honest review] I've tried countless serums, but IGK's GOOD BEHAVIOR Supreme Seal is next-level. My hair is naturally wavy, frizz-prone, and reacts to humidity like it's trying to escape my scalp—but this serum tames everything without weighing it down. It gives me that smooth, glassy finish and lasts all day, even in sticky weather. The scent is salon-fresh but not overpowering, and I love that it protects against heat too. A little goes a long way, and my hair feels soft, shiny, and manageable every time I use it. Definitely a staple in my routine now!
Prefect for living in Florida
I love it FL and I have waist length naturally wavy hair. This is one of the best products I have found to beat the frizz and it leaves my hair shiny with out being oily. I have been able to keep my blowout sleek for the last 4 days they rainy days and 100% humidity.

I would buy it again
I received this product in exchange for my honest review. For the most part my hair is always in a sloppy bun. So I don't use many hair products. I wanted to tru this to see if it would help with my frizzy bun. From what I could tell it did help. Its not a product you can use everyday. About every 3-4 days. I liked how it smelled and felt in my hands and hair. No sticky residue. Which is great. I'm definitely going to finish this bottle. Personally I wish it was something I could use every day cause I always forget things in my routine if it's something that is not constant. But that's a me issue.
Love it
[I received this product in exchange for my honest review] I have wavy hair but most hair oils are way too greasy and heavy for me. This stuff works great for my hair type and texture, it adds smoothness without making my hair look oily and it smells so good.
Good, but a little heavy for fine hair
[I received this product in exchange for my honest review] I liked this serum, though I'm not sure it's the best product for me. I used way, way too much the first use because I expected more of a liquid-y lotion and it's really almost a hair oil. It weighed my fine hair down significantly. The next time I used it, I did remember to use much less and I liked it more. I do less than a pump and evenly coat my hands. I run it through my lengths and ends and then finally go over the crown of my head with the little that remains. I think this would be better for courser, thick hair. However, I do think it helped a bit with my frizz and it honestly smells incredible.
