I found I had slight problems lathering up the nizoral shampoo because I would literally smack on a dollop of shampoo on my head and at times not use enough. I found the best way to apply nizoral on the scalp is by spreading it evenly across both my hands and massaging my hair with my fingers spread out to get deep in my hair. Don't be too gentle or else you'll accomplish nothing, i've always been overly gentle with my hair. Our hair is tougher than we think. O yes also make sure your hair is wet, running your hair in a shower for only 30 seconds doesn't fully soak your hair. I bathe usually when I apply nizoral so it is easier, but I try yo cup the water so it fully soaks my hair.
As ridiculous as it may sound but not properly washing your hair can be really bad.
