Sally Hansen Hard as Nails

I found this works for me, made my nails a lot harder and stronger, so it definitely done what it says it would do. I sometimes use it as a base coat or alone making my nails look smooth & shiny. However, I found that after a few days it starts to peel off making my nails look dry & flaky so you will need to apply regularly for the best results.

I started using this product a few months ago, hoping to strengthen my bendy, breaky nails. I continue to use it regularly under every nail polish, hoping to see results. I continue to use it, and would repurchase because it's a smooth base coat, but I'm not quite sure if there have been any changes in the strength of my nails. Some of my nails may have become tougher, but some of my other nails are still incredibly bendy. After reading other people's reviews though, maybe it's not meant to strengthen nails which are already there but somehow make new nails strong?

I have very weak, thin nails and this product did not work very well to strengthen them. I followed the instructions exact (apply the strengthener every 3rd day for 7 days in total, remove then repeat the process again).

I did notice on the first day (coat one) that my nails felt harder than what they did without it but by the time I added the second coat (day three) my nails didn't improve in hardness and the nail treatment started to bubble on my nails.

Using this product with the intention to solely act as a nail hardener it does not work for me but I do find it alright to use under nail varnish as a base coat.

For anyone with nails like mine (dry cuticles, weak paper think nails) I would not recommend this as a nail hardener but it is only 8.00 so it is cheap enough to have a go to see if it works for you. Worse case just use it as a base coat :)

It works.... not much more I need to say finally a nail hardener that actually works.

I finally have stronger nails not as hard as they could be used as tools but they aren't breaking as easy. This product is amazing,as long as your consistent in using it. I find I need to apply every few days but its quick drying. Slightly strong odor but doesn't last long.

I picked this up from The Warehouse on sale a while ago as I was looking for a nail hardener to use, and had heard good things about this one.

It comes in a clear bottle, with a normal brush. This doesn't smell too strongly, which is good. It's an average consistency, not too thick or thin however one time I went on holiday for a couple of weeks and when I came back mine had gone all goopy and thick, not too sure why that happened as I screwed the cap on tight but oh well. This did help my nails, but you have to use it continually or it stops working as well which is quite annoying.

I would probably buy this again, it's a good product for strengthening nails but when you stop using it the effects reverse a bit.

As a nail biter growing my nails is a struggle! I go through stages where I give up for a while and always use Hard As Nails to help me. If you are a biter you will understand how weak your nails get when you attempt to grow them. This definitely helps strengthen them and gives them a nice sheen too. I now just need to learn to give up permanently!

I have used this as my nails are not the greatest and often break and peel so I thought this would be the answer for me. I used it regularly and my nails did go really hard but they snapped off with any resistance .At first I thought the product was brilliant and my nails certainly were hard but I was forever having to file my nails as they were broken so yes it works but not suitable for me.

I bought this a couple of months ago when I ran out of the usual stuff I use (Sally Hansen Nail Growth Miracle) and they didnt have it in stock. Its definitely a great product that does what it says it will. Hard, strong nails that definitely dont break as easily as normal :) It dries really fast too which is great if you're using as a topcoat over colour!

i have very thin fragile naisl, im quite low in iron so my nails arent the strongest regardless but this product definitely helps keep them less brittle and prone to breakage, i wouldnt say that this makes my nails hard as such not on its own anyway but i did use it with sally hansen anti chip top coat with nail polish and my nails were so hard! but this product on it own isnt really perfect but still good and worth a try!
