Attention fellow bloggers I need your help!

Hello everyone! ,
I need some advice for a product and I thought where better a place then my blog? Anyways, I've recently cut my hair quite short like pixie short. I have quite thick flat hair that doesn't frizz or do anything really, but i would like a product I could put in my hair to give it a textured messy look. I have tried a few but none of which worked in the least. Can anyone recommend a product they like and may work? Thank you for all your help in advance!
