Best hair treatment for male losing hair(males please)?

My husband is a 25 year old. He has a (very)thin patch of hair in the back of his head and is very stressed out about it. We tried a special hair treatment and spray that was very expensive and gave no results.I was wondering what other men have tried and what works.Also is it normal to be losing hair at age 24? His dad is almost bald but male pattern baldness doesn't run in his family.
