Do vitamins work and is 2% Ketoconazole much better than 1%?

[BillButcher]

I'm talking about these vitamins, which are by the same company that makes Regenpure NT and DR, http://www.amazon.com/gp/product/B00YSZCSLC/ref=pd_luc_rh_sim_01_03_t_img_lh?ie=UTF8&psc=1

And I'm wondering about the shampoo, DR or Nizoral, will there be a difference if I get a 2% prescription rather than over the counter 1%?

And from our own site, has anyone tried these, and do they work? https://www.hairlosstalk.com/hair-loss-treatments/spironolactone-topical/index.php

The only thing that vitamins will do is help to correct any nutritional deficiencies, they won't help with androgenic alopecia at all. As for various ketoconazole shampoos, the 2% formulation is the most well studied and the only formulation studied for androgenic alopecia (both 1% ketoconazole and piroctone olamine have only been studied for dandruff/seborrhoeic dermatitis and telogen effluvium). In short, I'd highly recommend the 2% formulation, I can't imagine getting a prescription for it would be difficult.
