Answer
Hi,
thank you for your question.
You need to see a vet with both mice to find out what causes the bald spots. It can be mites or a fungal infection or something completely different. Both mice will need to be treated anyway.
www.rmca.org/Vets has a list of rodent vets.

Since you separated them, you will need to reintroduce them because by now they have lost their group scent and will not recognize each other.
Introduce them in the bathtub or somewhere else where they both haven't been before. If they get along there, put them in a kritter keeper or small cage without a house, just food, water, bedding and some hay to hide in. If they get along there, they can move into their normal cage after a day. The cage must be cleaned with hot water and vinegar to get rid of the smell and must be just as empty as the small cage. If they continue to get along, you can give them toys and furniture, one item per day.

It's usually better to leave sick mice with their group. Separating them is just stress and may worsen their condition and when it's something infectious, the whole group will be affected by the time you noice something is wrong (mice are very good at hiding illnesses).

I hope I was of some help to you
