I have been using Dualgen 15 for 6 months now, the first 3 months I used the No PG but found it goes kind of sticky and so decided to try Dualgen-15 With PG and I have found it much easier to apply. I have had no reactions with either product and I think the results have been very good.
I prefer to use 15% minoxidil as it means I dont need to be applying it twice a day. I apply it in the evening and wash it out after a couple of hours.
The service from MinoxidilMax has always been good and products have always turned up quickly.
