I remember seeing this advertised in a magazine years ago, back when I was at school. This really appealed to me as I rarely consume any form of calcium. (Yes, I’ve tried taking vitamins but I am so forgetful!) Which in turns make my nails really weak and the top layers always seem to peel away.

I persuaded my Mum to get it for me and I’ve been using it ever since. I know some people much prefer O.P.I Nail Envy but it’s twice as much as Nail Growth Miracle, which does exactly what I need it to.

I’ve recently heard formaldehyde can be bad for nails as it makes them peel but I don’t find this a problem at all. I Googled this the other day and found out that only prolonged use of formaldehyde causes nails to split. So I guess it'd be fine to use this till I get my nails the length I want!

I hadn’t used this for quite a while, I was trying to let them grow on them own but they just kept breaking. So I repurchased this last Friday. So I’ve been using it for just over a week. I forgot how good it really is. It makes my nails grow faster and look a lot better! This is definitely my holy grail for nails.
