I have the same problem, After a scalp sample, my dermatologist diagnosed me with Rosacea of the scalp (which apparently is extremely rare in less than 3% of all Rosacea.) Anyways, so I have always had an extremely sensitive scalp with burning and itching, so when I began Rogaine solution it set my scalp on fire to the point of using cold packs and ice. My life was completely changed when my Derm prescribed me Clobetasol Propionate 0.05% scalp solution. I use it twice a day and about 1 hour before Rogaine give or take 15 mins. It's a Class 1 corticosteroid, so it's one of the most potent ones available and it stops all burning and itching and irritation instantly. And personally I experience no side effects. I use to nearly cry when applying anything with an alcohol, like Rogaine, but now it's perfection. Clobetasol is actually used to treat Alopecia Areata and regrows hair on it's own. And ps there is no other solution that penetrates your scalp as a vehicle for minoxidil better than PG I feel, despite what marketing and others may believe. (Rogaine came out in 1988, if there was a more effective vehicle the formula would have been altered within the nearly 20 years it's been available, and the only other form is the foam which is without PG, but is much less effective because your hair absorbs most of it and it does not sit on your scalp long enough) Hit up your doctor, be straight up. Also, all these treatments I use dry out your scalp, so to soothe it I simply use an all natural conditioner and gently rub the scalp while showering and it stops any additional irritation, I use Burt's Bees Very Volumizing. And moisturize your forehead where you place the treatments at least twice a day with a oil-free, dye-free, fragrance-free, gel moisturizer, I use Clinique Dramatically Different Gel, or Soy Face. Good Luck man, hope this helps
