Terrible for me :(
This was terrible for my nails!! If anything it made them worse. Excited to buy this after a friend recommended this product, convinced this was the answer to my weak nails, I followed the instructions to the letter. My nails would break by brushing them againsty desk. Running my fingers through my hair? The strands would catch in these sliver breaks suddenly in my nails and get stuck. They would break simply by accidentally hitting them on something (my nails aren't that long to begin with) and they'd break right down into my nail bed.
