Fur thinning

[Tiffanyh]

Hi!

I'm just after some advice, I've noticed recently that the hair around my hamsters face seems to have thinned out and his skin looks a little bit red sometimes. (I've attached pictures but they're not the best)

I bought some carefresh bedding that I usually get and I noticed that it felt more rough and was a slightly different colour to usual so I'm not sure if they've changed it in some way and when he's been burrowing it's caused irration on his face.
He's only 9 months old and he's still his usual self but I just wondered if it could be something else? I read that their hair can thin around this time of year but find it odd it's just mainly around his face.

Is there anything I can give him to help it grow back a bit? I've seen that flaxseed is supposed to be good for that.

I've also bought the carefresh confetti bedding which felt a lot softer than the plain brown coloured one, so hopefully that will help as well.

Thanks
