If you ride a horse, a bicycle, or a Harley, drive a really fast car, or choose skates, skis, or football cleats as your favorite mode of transport, one wardrobe item is mandatory – a helmet. While protecting your head, of course, a helmet can wreak havoc on your hair. Some enthusiasts who ride their bikes to work even complain that their colleagues can detect what brand of helmet they wear by the imprint left on their locks! But it’s not just style that suffers from prolonged contact with a helmet. It gets dirty and sweaty in there, especially when the weather is warm. All that extra dirt and sweat lead to clogged pores and excess sebum production, and an oily, irritated scalp that doesn’t respond to ordinary shampoos and conditioners.
