I am a 19 year old male and since August of 06 I have lost a significant amount of hair due to shedding and maybe miniaturization (some hairs that fall out look much thinner than others). From about february 06 till august 06 i was on a very reduced calorie diet and lost about 80 pounds. I can’t help but think there is some connection between the weight loss and hair loss.
My first question is: could that restrictive diet have caused my early and rapid onset of hairloss? Also, I have currently been taking propecia for the last 2 months.
My second question is: will taking vitamins (which ever ones they say promote hair growth. ex.Vitamins B6 and biotin) along with propecia help promote new growth? or are vitamins ultimately uneffective against hairloss (assuming its MPB)?
Thanks for your time, and your site is by far the most informative i’ve found so far.
Nutritional deficiencies (or as you put it, restrictive diet) can cause hair loss. In addition, this may trigger a stress response and turn on a gene that may kick start your male pattern hair loss. Unfortunately, after the process has started it is difficult to stop the progression of hair loss.
In either case, you should have a balanced healthy diet. And if you are concerned about male pattern (genetic) hair loss, you should see a doctor to get the correct diagnosis. Propecia can only be prescribed by a doctor and even if it is readily available over the internet you should see a doctor for a correct diagnosis and appropriate follow up.

After receiving your email, I wrote to a group of well-respected doctors to inquire about experience in this area, and the general consensus was that this should not be treated surgically. Most of the doctors I wrote to were dermatologists who may have an aversion to scalp reductions in this situation. You need to be evaluated by a surgeon, perhaps a very specialized plastic surgeon who has experience doing this surgery in a patient with your diagnosis. Logically, scalp reductions should work, but I wouldn’t recommend that you be the first patient to attempt surgery to correct this condition.
