Vitamins for hair loss?

My friend is worried about hair loss lately. She's on medications for her thyroid, which might be a partial culprit, but I think she needs better nutrition. I know B vitamins are good for hair loss. Anything else? I was thinking prenatal vitamins, too. My hair was super thick when I was on those!Vitamins for hair loss?
There are two reason for hair loss if she is hypothyroid: 1) being on the lousy T4-only meds like Synthroid, Leovyxl, Levothyroxine, which leave nearly everyone with lingering hypo symptoms, including hair loss 2) having low storage iron, aka low ferritin, which is common with patients on the lousy T4-only meds and causes hair loss.



Read this about why T4 doesn't work and can cause hair loss: http://www.stopthethyroidmadness.com/t4-



And this about low ferritin:http://www.stopthethyroidmadness.com/fer



And she should read the entire Stop the Thyroid Madness website, a thyroid patient advocacy website by Thyroid Patient Activist Janie Bowthorpe. Janie also wrote the book by the same name, and readers report liking it even more than the website, since it's easier to refer to, and has even more info.
