I have no concern about helmet hair at all. When I ride to up I usually dewrag w/a braid. When I ride myself I wear a helmet...then I just do a braid usually.
I figure the peeps I'm with are all bikers too. Who really gives a rat's ass?
If I do anything it's ..unbraid it...run my fingers through it...voila.
OK GIRLS THIS IS WHAT YOU GOTA DO FOR HELMENT HAIR ALWAYS CARY A COMB OR BRUSH IN YOUR BACK BACK WHEN YA TAKE OFF THE HELMET LEAN FOWARD AND COMB AND SPRAY SHAKE YOUR HEAD BACK AND FORTH A COUPLE OF TIMES, LOOK IN THE BIKE MIRROR PUT ON SOME LIP GLOSS AND GO !!!
