I have been wearing the qwest for a year, I think it was a bit itchy/uncomfortable all along, but it's got really bad this last few weeks/months.
I went for a ride this evening, I had a shower before I went but didn't wash my hair, itch wasn't bad, resisted the temptation to move the helmet abit with the chin bar to sort of itch my head, I think I may have been shampooing the hair too much, I'm going to shampoo only once or twice a week for while to see if it helps, I'll also look into getting a do rag
I have some Motul interior helmet cleaner, it came with a set of free gifts I got with Bridgestone tyres one time, I shoot a spray of that into the helmet sometimes it freshens it up and disinfects I think.
I'll remove the liner and wash it, but I think washing the hair too often could be the issue, I'll see, thanks for the help guys.
