I Have Psoriatic Arthritis and was prescribed daily 20mg Leflunomide last year, but after 4 months as my hair was falling out in clumps and large amounts I stopped. As from January this year the arthritis has flared up very badly again this time affecting my feet which are very painful in addition to me beginning to lose all my finger nails!! The specialist said to try Leflunomide again at 10mg daily. After 3 months no affect what so ever in controlling the arthritis so he has now given me Methotrexate (only had 1 dose so far) to take as well as the Leflunomide. Problem is this week my hair has started falling out again!! A hairdresser suggested i use Nioxin to help combat this, has anyone used this or tried any other scalp treatment with any success?
