I am a long time user of the 5% minoxidil Equate brand from Walmart and am going to switch to Kirkland 5% brand minoxidil to see if it is any better at keeping side effects at bay. I have a big problem with dizzy spells and psoriasis and I do think the minoxidil plays a part in both. Has anyone else tried both brand and could you tell any difference between the two? Kirkland from costco is also cheaper.
