Got hair that frizzes in humidity? I do. But I recently discovered a new anti-frizz treatment from my favorite haircare brand, IGK.
IGK recently launched a new line extension to their Good Behavior collection: Supreme Seal Anti-Frizz Serum. I washed my hair on Friday with IGK More Life Color Extending Gloss Shampoo and Conditioner and IGK Expensive High Shine Gloss Treatment, as I usually do. It was a warm day and the weekend called for intermittent rain and higher humidity.
After drying and styling my hair, I applied new IGK Good Behavior Supreme Seal Anti-Frizz Serum. The directions say to apply Anti-Frizz Serum to hair from mid-length to ends. I pumped out some of the lightweight “oil” and applied it to all of my hair because I get frizz above mid-length. I applied it with my hands and ran my fingers through my hair. Smoothness ensued!
Here’s my hair on Day 2, the day with the most humidity:

Today is Day 4 since I washed my hair and applied Good Behavior Anti-Frizz Serum. In spite of doing some gardening, hiking and mowing the lawn today, my hair is still smooth. No frizz!

IGK Good Behavior Anti-Frizz Serum is supposed to provide frizz-free hair for 4 days. It worked for me! In fact, I usually wash my hair every 5 days, so I will be curious to see if my hair still looks as smooth tomorrow.
In addition to keeping hair frizz-free, Good Behavior Anti-Frizz Serum:
- boosts shine By 75%
- provides UV protection
- tames flyaways even in high humidity.
I’ve been using IGK Expensive to make my hair shiny, but the next time I need Anti-Frizz Serum I will skip using Expensive to see if Anti-Frizz Serum will make my hair shiny and glossy on its own.
As we move into summer and I’m outside a lot, the UV protection is very important to me.
So this is my first impression of IGK Good Behavior Supreme Seal Anti-Frizz Serum. I truly hope that this serum will become a product that I can depend on this summer for smooth, frizz-free hair that doesn’t fade quite as fast as it has in the past.
IGK Good Behavior Supreme Seal Anti-Frizz Serum contains 1.7 fl. oz./50 ml and is priced at $34.
BTW, IGK is offering 25% off on everything on Memorial Day. It’s a good time to try out this new product if you have frizzy hair like me. And if you do shop IGK, sign up for loyalty points. I am qualified to get $10 off in addition to the sale price. Good one!





This is so interesting. I find the frizz spray to have some fragrance, what about this?
This product is not a spray. It is a lightweight oil delivered by pump. But you are correct, fragrance is on the ingredient list that I forgot to post. I will update it. The fragrance is almost imperceptible, but for you, it would be a no-no.
