Good Behavior Smoothing Spray

  • Valerie M. - Verified Buyer

    I can't stop raving about this product to my friends who ask me how I get my hair so smooth and soft. I use it after shampooing my hair to keep my curls soft and smooth and I liberally spray it on before I use my straightening iron. It looks like I just left the salon.

  • JoJo. - Verified Buyer

    With this product my flyaways and frizz are at bay! I am so happy I purchased this along with the rest of the Good Behavior line! I also apray on my dry styled hair b4 hairspray. My hair is so happy! My hair looks pretty and I am in tears writing this due to it has been so dry and damaged! Not anymore and only used a couple of times! Do not stop making this product!

  • Amy S. - Verified Buyer

    This is the absolute the best smoothing\heat protectant I have ever used. It totally changed my fragile fine hair into softer stronger tangle free hair. Even after washing it I no longer need my leave in detangler, my hair is already tangle free. I am absolutely in love with this product!!! Wish I found it sooner!!!

  • Sarah - Verified Buyer

    Buy it! It actually works. I have THE worst hair, super thin, brittle, frizzy and to top it off thinning more due to my thyroid. I bought this and it actually makes my hair look good! I spray my whole head after showering and it makes my hair shiny, straight and frizz-free! I don’t ever write reviews but this is a stand up product that I can’t live without.

WHAT IT IS

Spirulina protein in IGK Good Behavior Smoothing Spray strengthens and nourishes hair, while a unique formaldehyde-free bonding polymer, activated by heat, emulates keratin treatment's smoothing effects. This spray reduces blow-drying time, and offers protection against humidity, heat, and UV damage, ensuring soft, shiny, frizz-free hair with 24-hour frizz control and 450°F heat protection.


PRO TIP

The best part about Good Behavior Smoothing Spray is that you can use it any time you heat style. Whether your hair is damp or you need to refresh dry, day 3 hair with an iron, just apply it generously and style!

Worth the buy!

I don’t necessarily have dry hair but my hair is frizzy and this helps calm the frizz and makes my hair feel so soft. I use it after I blow dry my hair and so far love it. The smell isn’t bad but it’s fragrant in case those of you are sensitive to smell.

Witchcraft.

I have no idea how this works so well, but it does. I love doing heartless curls overnight (Eternal Muse products are the best for this) and when I wake up, my hair looks pretty cute. Then I spray this witchcraft concoction and I suddenly—literally—look like I just walked out of the salon. Smooth, shiny, and the curls magically look 10x better?! I have used olaplex and all that, and this looks similar to when I’ve done a length olaplex treatment. Except that it’s just a quick spray. Not heavy, not greasy. Smell is a bit strong, but not bad, and I would saturate my hair with this even if it smelled like bad eggs. It’s that good.
