I have brittle nails that never grow more than a mm without splitting and currently very short hair which I absolutely hate! I have read that Biotin and Vit B complex are beneficial for hair and nails. I doubt i'm clinically deficient in anything as I eat a decent diet, but I do remember my Mum giving the cat Vit B (brewers yeast) tablets when her fur was looking tatty and it really helped .
Not that I want shiny whiskers and a gleaming full tail, but still!
Just wondered if it was worth giving supplements a go or whether I'd be weeing money down the drain!
I take high dose B vitamins. They make my pee go bright yellow, and when I ran out a while back my face erupted in a horrendous rash of weird spots which took the next several months to mature into little hard beads which would then be ejected from my suffering skin. I went back on them and haven't dared stop since.
I take vitamin b complex, glucosamine sulphate, iron, omega 3 fish oil and evening primrose oil supplements.
My nails are stronger and less brittle, my circulation has improved and my hair is glossy. I bought them either at the pound shop, Wilkinsons or Morrisons so they didn't cost much. I feel better on them, it's with a try!
