Hi Johnson.
Hair loss primarily is dealt with for men in the way of medication and usually FDA approved such as Minoxidil and Propecia as the most widely used and wise to see your GP or specialist to see if suitable for you personally.
Surgery will not deal with loss as such but with disguising loss and giving an illusion of coverage with skillful surgery be it via FUE or Strip and for that most clinics will offer a free consultation and look age your age, medication, goals, loss, donor etc.
Feel free to post your case if you wish to and have some feedback from the clinic and users here as well as the moderator.
All the best.
