Which tablet is better for hair growth: Surbex-Z or Perfectil?

This needs an in-person evaluation. I suggest seeing a hair loss expert now to evaluate and go over your condition and provide you information about your best treatment options. There are great non-invasive options like prp/progesterone and/or hair transplantation. See an expert. Best, Dr. Emer

Yes, bloating has been reported, although it is quite rare. I recommend consultation with an experienced hair surgeon to help figure out options. As the swelling could be an allergic reaction, I recommend that you immediately stop taking the medication.
