I also lost most of my hair due to poor nutrition and all the meds I have been on . Especially Prednoisine.
I tried Biotin coconut oil and other crazy stuff nothing helped.
On the advise of my hairdresser I bought a wig.its the same grey color and style of my old hair.
Never looked back , now own 3 wigs.
Iam still too skinny at 98lbs,but hey at my age feeling good at how my hair looks
