Ojon spraying system is total rubbish. I had 3 separate cans of the their hairspray from John Lewis and each has worked for a short time before completely blocking, despite taking the sprayer off and soaking it in hot water after each use. You really don't expect that from a product costing £24.50. I emailed Ojon UK and they told me they were changing their spraying system and would send me one when they were in stock. I received it last Tuesday but to my disappointment it's identical and is already needing rinsing under the hot tap after every use. I'm deliberating whether it's worth telling them they've sent me the old stock or whether to just give up and put it down to experience. In any event I've lost all faith in Ojon, but that could all change if Dennis happen to knock on my door to apologise in person!!
