My nails are just a hot mess they are literally paper thin, I zip up my jeans and I have torn or broken 2. So I always keep them short and try have gel on them to harden them (which can get expensive) so I found this product at Dischem actually and started using it at home under the nail polish I would use. To be honest, I really did help, lasted about 2 weeks or so - which I know sounds short but for me that is amazing. But I recently I learned that there are 7 layers to your nail and I am apparently on the last layer which is why my nails are so weak.
So despite my nails needing salvation lol, the product did work me and I did see a difference. :)

I usually suffer from brittle nails and they don't grow very long without breaking
I found that this is made my nails strong and aided it's growth.
But as soon as I took it off to give my nails a break... my nails would chip immediately and left a yellow hue on my nail bed. But it helped my grow my nails though
