Yasiel Puig had 11 of the strongest barbers on the planet give him a brand new look Thursday night ... getting a fresh bald haircut from kids battling cancer!!
The Dodgers superstar rolled into Cedars-Sinai hospital in L.A. where he decided to get his head shaved as a show of solidarity with all the tough kids in the hospital going through chemotherapy.
The kids loved it -- and so did Puig, who addressed every kid as his "new barber."
Puig your friend.
