It will do more than wearing nothing at all if they get hit in the head with the ball or a stick. If you are concerned about how your daughter looks on the lacrosse field maybe she should be in beauty pageants instead of playing lacrosse. My daughter played and suffered a concussion from taking a shot to the head - and yes, she was a good player, and certainly not a "WUSS" as you so eloquently put it. It will not be a choice you need to make for you daughter much longer. It will be a mandatory piece of equipment shortly. If you feel strongly enough that the current style of helmet does not provide you daughter with enough protection, contact somebody at Cascade and voice your concern rather than spewing your ridiculous opinion on a message board.
