These flashbacks are from before he was in the rift.
It's not a plot hole, but I won't say more than that.
His real color hair color is black, it only turned white as a side effect inside the rift and remained white when he came out. Rn he uses hair dye to cover his white hair but his original hair color is black
I thought his hair was white. In chapter 2, when his past was shown where he was pushed out from the Rift and when he first went to the Hangover Soup Shop, it looked white. He even colors his hair a darker shade in chapter 7. So, what is his real hair color?
