DIY: Dry Shampoo

One of the best selling dry shampoo is Klorane's, they say it works but... is it worth spending more than 15$ for it? 

Here you can have a look at the ingredients: 

Butane, Propane, Isobutane, Oryza Sativa(Rice), Starch(Oryza Sativa), SD Alcohol 39-C(Alcohol Denat), Aluminium Starch Octenylsuccinate, Avena Sativa(Oat), Kernel Oil(Avena Sativa), CYclodextrin, Cyclomethicone, fragance(Parfum), Isopropyl Myristate Slicia. 

As you can see there are only two active ingredients, oat and rice starch, nothing more. So why don't you take a couple of minutes to prepare your own personalized dry shampoo?? It is lazysafe I promess ;) 
Here below I'm gonna share a simple and effective formula: 
- iris powder 1/2 
- cornstarch 1/2 
- essential oil of your choice (a few drops)  
Mix it all properly, possibly in a coffee grinder and put it in a nice pot with puff! (Always close it well and don't leave it in the bathroom, because of the humidity)
