The "Full House" alum revealed Thursday that he wasn't able to shave his head because he's filming a new project soon — and said the criticism "really hurt me."

Now, on Instagram, his “Full House” co-star John Stamos shared images of the lifelong friends together. Stamos was wearing a bald cap and shaving Coulier’s head. “Nothing like throwing on a bald cap and flexing some Photoshop skills to show some love and solidarity with my bro, Dave Coulier,” Stamos wrote.
