LaMelo Ball just changed his image in a big way -- losing his signature shaggy hairstyle ... and replacing it with some killer waves!
There had been rumors LaMelo axed his Odell Beckham-style hairdo after he came back from Lithuania ... but now he's confirmed the change -- posting the pics on Instagram.
Looks like 'Melo's hair inspiration could be his own brother, Lonzo ... who has a similar wavy cut of his own.
It's a bizarre move for 'Melo considering the hair was part of his signature look -- and helped him stand out from the rest of his family.
