The Jury is Still Out

Admittedly, I have not been very consistent about using this product. I am a nail biter and tend to avoid giving much attention to my nails whenever possible. I purchased this product hoping that it would motivate me to take care of my nails/hands, but unfortunately, a magic pill was not included in the packaging. I can say, however, that the SI-Nails is very fast absorbing and easy to use.

Only lasts two weeks

This stuff works quickly to lessen ridges and splitting nails but it’s ridiculous how little you get for the price. I keep buying it because it works so well but it makes me mad everytime and I’ll keep looking for something else.

I don't see a differernce

I have been using this for a couple of weeks and my nails are still brittle and splitting/peeling. I don't know if it takes longer for this product to work or if it's just not worth the expense.

I think it’s working???

There are so many variables when trying to determine whether a product is working, but I think I’m seeing a change. Because I swim, my nails are perpetually splitting. This seems to be helping. I was surprised to see that the directions say to wipe off any serum that gets on skin. I thought that it was supposed to help cuticles. Wiping off makes use a little less convenient.

Hard Pass

This product didn’t help my nails even a smidge. It did apply well and dry fast however.

Perhaps I expected too much

Two of my nails have recently started to split, and I had hoped that this product would stop any additional splitting by strengthening the healthier part of the nail. After a couple of weeks, I haven’t seen any real improvement. This nail serum did seem to moisturize, and instantly improve the appearance of my nails, so there has been a cosmetic benefit.
