Dwyane Wade Debuts Black Lives Matter Hairdo Amid NBA Boycott

Dwyane Wade is making a statement without saying a word ... showing solidarity with his NBA friends and former teammates by debuting a Black Lives Matter-inspired hairstyle.

The sports world came to a screeching halt following the shooting of Jacob Blake in Kenosha, WI ... with the NBA, WNBA, MLB and NFL postponing games and practices.

Wade -- who has been outspoken about social justice throughout his career -- revealed the bleach-blonde style with a black fist on Wednesday ... right after the Milwaukee Bucks refused to take the court in honor of Blake.

The future Hall of Famer has also been spreading his message with his wardrobe recently, sporting a "Shoot hoops, not people" shirt.
