Of course I get a lot of hairinspiration too on Pinterest. You often see the most pretty girls with the most pretty hair. It can happen that you become jalouse of it, but you can also get some inspiration from it. I often look at the colours and how they are made and what kind of colours they used. Or how a haircut is done and how pretty it sometimes suits someones face or appareance.
Dangerous is, that I want to change my hair a lot or want to try a different colour every week! Thankfully my colleagues know how to tame me down a bit;)
