Nail strengthener - best tips?

[gonerogue]

Hi,

I have bitten my nails forever and have in the last few months stopped doing it. However, once my nails get to a certain length they just snap at the slightest provocation. I have no idea how to make them stronger, any advice?

TIA

I found Sally Whatshername absolutely crap. Am hoping to get my money back re Dr. Lewinns. Expensive and crap

Most purported "strengtheners" contain formaldehyde, which irritates my skin and make nails so hard that they become brittle and breakage-prone. The Lady Soma Skin Nail cream worked better for my nails, but you have to use it for like a month till you notice a difference.

Vitamins! The pregnancy vitamins make my nails rock solid! I think treat from within so they grow strong rather than trying to make them strong once they arrive
