Assalam o alaikum

I was applying rosemary oil it’s been 3 months the result was so good that I wasn’t seeing any hair at all but I don’t know what happened now since a month I’m facing severe hair fall after using rosemary oil, I had hairfall before as well but not that bad, I diluted the oil with coconut oil but I don’t know what to do now, should I stop using it ? Or continue it ? I don’t have any rashes or irritation
