Why is Ken's hair not as bright as it used to be? Is the curse fading it or smth

i think his hair shines brighter in the moonlight or smth like that?? it was mentioned a few chaps ago but it might just be my imagination

Yeah his hair shines in the moonlight or at night since he's the human of moon and during day time they become dull it was mentioned before when they met with daniel for the first time...in that chp i guess
