The hair is comin' off! Scott Disick has ditched his wild, wooly, mountain man look for a cleaner, preppier look for fall and we love it!

Of course we love ALL of The Lord's looks and the mountain man look was pretty hot, but this'll do, too!

Rumor has it, girlfriend Sofia Richie wanted Scott to ditch the wavy locks and the scruffy beard ... so did he do this for his lady?
