Yes. The only illegal tackles are the horse-collar (grabbing the jersey collar from the back), grabbing the facemask, or leading with the helmet (e.g., spearing or helmet-to-helmet contact). The NFL also disallows tackling by tripping, but this is rarely called.
If a player wants to have a bunch of hair flying around outside his helmet, he does so at his own peril. It would be an unfair advantage if the defender was forced to carefully avoid the hair when trying to make a tackle.
