It’s quite expensive but I can’t be without it. Got this size to try and have just purchased the big size. Luckily as you don’t need much it will last. My hair would always feel greasy after washing and I randomly started suffering itchy scalp and dandruff. I use this once a week and my hair stays clean for about 4 days. I have no dandruff and no buildup. The bits are quite sharp if you step on them in the shower lol! 

this is the best thing that happened to my head, I have never had such a clean head, and volume appeared even without styling

Makes my scalp feel lovely and fresh. Really helps with dandruff.

Leaves my head feelings so clean. Only need a tiny bit so the travel size has currently lasted me five washes without even making a dent. 

I have an oily scalp which means I have to wash my hair daily and sometimes if I was to wash my hair at 6am come 3pm it would start to look flat and greasy. I have used this product a couple of times now and I am amazed! It smells UNREAL! My hair doesn’t get greasy and I can strech my hair wash out to every 2nd day. I bought the 75ml to try but I have already repurchased the bigger 250ml size as I will not be without this!
