Good Behaviour Spirulina Protein Smoothing Spray by IGK – A Review


The Intro

You know the scene in Harry Potter when Hermione walks down the stairs into the ball? She’s in that gorgeous pink, flowy dress and for the first time, her hair is gloriously smooth and shiny. This is what IGK’s Good Behaviour did to me. That’s right, it gave me a princess moment.

My hair has always been frizzy and even though my hair is as fine as spiders legs, given enough humidity, my hair can certainly give Hermionie’s a run for its poofy money. I’ve got all the frizz types. Fuzzy flyaways on top of my head, frizz in my curls, (I have mixed texture hair, love that for me). I also have poofy frizz, static, and I don’t even know how this is possible given that the frizz usually makes my hair giant and poofy, it sometimes does the opposite, making my hair flat on top with extra fuzzy frizz on the top of my head. It’s bizarre. So as you can imagine, I spend a lot of time, money and agonizing emotions trying to get my hair to behave itself and smooth out. Most of the time, frizz-reducing products only slightly tame my frizz, but it still rebels and fights back in all sorts of ways. Then I happened upon Good Behaviour and let’s just say, my hair met its match and finally decided to obey.

The Down and Dirty on Good Behaviour, Smoothing Hair Magic in a Can 

Good Behaviour is a keratin-like treatment, featuring Spirulina proteins and special bonding polymers that smooth the hair and protect it from damage. It’s lightweight and will not weigh hair down (even the finest of hair, like mine). It’s formaldehyde-free as well, which is the major win in my opinion (usually bonding treatments involve some sort of formaldehyde, check out this article for more on keratin treatments).

The Breakdown 

Good Behaviour is $32 for 5.6 oz of product. It’s a heat-activated spray that uses spirulina protein to smooth and protect the hair. It’s very easy to use, they say you can flat iron to get the best possible result, but I’ve found that all you need is a blowdryer and round brush for an amazingly smooth result to die for. 

The Scoring 10/10 

Good Behaviour is the most amazing smoothing product I have ever used. It feels magical. It’s easy as pie, no learning curve to get it right, plus it’s actually good for your hair and it protects it from heat, oh right, as if it couldn’t get any better, Good Behaviour smells incredible too. It’s everything a hair product should be, it holds up to all it’s claims brilliantly, as in it works, it really, really works. It also is good for the hair and doesn’t have bad unhealthy ingredients (love that). Another bonus is that it has UV protection, ugh, Good Behaviour really is the gift that keeps on giving. So if you want your own Princess reveal moment, grab yourself up a can of Good Behaviour, she’s like the fairy godmother of smooth, shiny, frizz-free hair. 

The Pros & Cons 

No Cons, only pros, I’ll just leave it at that. 🙂 

Tips and Tricks

Instead of writing out my tips, I’m going to give you the gift of visuals, as in, some of my favorite hair tutorials that feature great blowout techniques so you can get the most out of Good Behaviour and have the smooth, smooth hair of your fairy tale dreams. 

  1. This is a blowout tutorial by the great Anna Lee from the Chaz Dean Salon. This video actually helped me understand and (start to) master the blowout. It’s very in-depth, but also easy to understand, I highly recommend. Also, fun fact: When I went to school in LA, I got my hair done by Anna and her blowouts were to die for, also she was unbelievably sweet and cool.
  2. This is a great video by The Small Things Blog where you’ll see a blowout technique featuring a flat brush. She also goes over several common mistakes you might not realize you’ve been doing with your blowout and how to fix them.
  3. I wanted to also give you a quick video that features Good Behavior so you can see how it’s designed to be used.
