A heat-protective blowout spray that mimics the smooth, frizz-free results of a keratin treatment. 100% agreed their hair looked like they got a keratin treatment at a salon.

Spirulina protein strengthens and nourishes while an innovative formaldehyde free bonding polymer mimics the coating and smoothing properties of a keratin treatment when activated by heat. GoodBehavior also helps to cut down on blow-drying time and helps to protect against humidity, heat and UV damage, leaving hair soft, shiny and frizz-free.

24-hour frizz control. 450*F Heat Protection.

How To Use:

  1. Mist over damp hair in sections.
  2. Comb through, ensuring every strand is thoroughly coated from root to tip.
  3. Blow-dry in sections to seal in the treatment with heat.
  4. Style as usual or apply again and finish with a flat iron for maximum smoothing.

I loved using this on my hair when I straighten because it always gets frizzy since I have curly hair. This didn’t make my hair stiff at all or make my hair smell weird either. Really helped it stay straight I definitely recommend.

I love this IGK product!! I personally use it right before I straighten my hair for protection and shine - it not only makes your hair look healthy and strong but it smells SO GOOD I almost want to say the smell reminds me of chocolate in a weird way... weird but delicious.

A little expensive. Bought it at Sephora with the coupon. It tamed my long, wavy, thick brown hair for a few days and did feel like a keratin treatment. It eliminated my hair’s response to humidity, even in a rainstorm.

I prefer Oribe dry conditioner spray to smooth my hair. My hair is very coarse and it needs something heavy to keep it looking smooth. It didn’t really meet my expectations.

I love this!!!! I typically spray on my clients hair prior to a chemical service. This is a good price of course I get it discounted but retail value is awesome!

I found out about this in a magazine. Good Behavior is a fabulous name for this product .I have short hair but it's very wavy so I have to pull the waves out.Good Behavior helps me to really pull it straight and in the morning when I get up it's still straight it has stayed straight for four days Love ,love, this product .It says it's a keratin like product in a can,I believe it.I would recommend this to anyone who has waves and what's straight hair.

I’ve gotten a keratin treatment before and loved the results so the description of this product really intrigued me. I’ve loved a ton of products that I’ve already tried from IGK so I’m really interested in trying this one as well. I have super super long, thick hair that’s curly/wavy when I let it hair dry but if I blow dry I becomes a literal lions mane. It’s so hard to keep up with a tame so I’m curious if this will actually reduce frizz in my hair and make it more manageable? Would love to hear your thoughts if you’ve used this! Thanks!
