Zinc Shampoo for Treating Hair Loss?

What I believe to be a reputable private practice hair transplant specialist here in San Francisco advised that I exclusively use a 2% zinc shampoo, a recommendation he apparently makes routinely for hair loss.

I however have read conflicting information about the value of topical zinc for men experiencing hair loss, and even that it may accelerate the process. Do you have any thoughts on this issue?

BTW I have not yet undergone any transplant procedure.

Thanks, and with regards

Zinc will not help with treating genetic hair loss. There may be such things as zinc deficiency that can cause hair loss, but that is diet related (which has nothing to do with zinc shampoo). Your reputable private practitioner seems like a good entrepreneur, as well. Sometimes I think about going into the shampoo business…

There was a small study published 7 years ago that said there was a modest improvement in hair growth in those that used a 1% pyrithione zinc shampoo, but it also said that the benefits were only apparent to the investigator and not the patients using the product. Some marketers will use that weak study as a sales point for zinc shampoo.
