I’ve only been using this for a few weeks but it definitely stimulates my scalp, so I’m hoping for good results in the longer term. It smells pleasant and doesn’t make my hair look greasy, which is something I was a bit worried about. Be careful when you apply it though - I accidentally spilled some and it ran down my face making it look burnt. Thankfully, I found that applying a wet cloth for half an hour or so eventually calmed it down.
