Dancing, I have tried several brands of so-called nail hardeners, including Sally Hansen, but I have found that, as Chevaux posted, leaving them bare keeps them stronger.
I don't want them long, that's for sure. I am out doing physical work too much as well to have to "worry about my nails". But I would like them just long enough that I can actually use them for something, like picking off tape, wrap, etc., and that I look presentable at my office job. Due to the type of employment I have, people look at my hands alot and it's kind of embarassing.
I have tried googling, but not much success there either. I look at the recommended vitamins and minerals and according to what I eat, I think I am getting enough. There are no telltale signs of deficiency in my nails (white spots, moons, ridges); my hair is lovely and strong. I just looked up biotin and it's available in nuts, which I eat, but maybe I'll take up putting some gelatin in my diet.
It's hard on the internet because many place equate soft with brittle and that is definitely not the case. Soft is bendy. Brittle is hard.
Thanks for the ideas.
