Sally HansenNailgrowth Miracle®, Nail Strengthener, Nail Protectant, Nail Serum, Includes Biotin and Peptides

This is still the best thing I've found to strenthen nails and help them to grow.

Love this stuff see results in first week. Great price on Amazon. Always order extra they run out fast. Sally hansen has great products.

Can’t believe the growth of my nails! I highly recommend this product.

Hydrating and feels nice going on the nail but I haven’t noticed any difference in my nails.

When I initially received my order, I wrote a review stating the product did not come with a dropper, and that the serum was extremely thick (or "goo", as I called it). I found the dropper was actually tucked in the corner of the box, so it was an oversight on my part, the vendor was not at fault. And, from the research I've done, apparently, the serum is thick. I will follow up later to speak on the how well the product works on my nails.Note: The vendor immediately responded to my negative review to address my concerns and ensure that appropriate action was taken to make sure I was satisfied with my purchase. I appreciated that.

I had severe damage on my nails after more than a decade of using acrylic and/or press on nails (even had some damage to my nail bed on a few fingers). They looked AWFUL. I needed something that would help strengthen, heal and help my nails grow fast. This stuff was cheap, and had some rave reviews on beauty blogs. Short story: it WORKS. It (for real) instantly strengthens nails so they don't bend or tear. It allowed me to grow out my damaged nails quickly. I used it daily, under and over polish. It just worked when nothing else did. It only took about a week for me to notice significant improvement and growth.Note: unlike some hardeners, this one doesn't make your nails brittle, so no chipped nails! It does nothing for cuticles, but there are other products for that. This product is fantastic.

Truthfully, this stuff has made a huge difference for me. I have a problem not only biting my nails, but also my cuticles and other over grooming things. I've tried lots of things and the biggest help was fake nails but my nails were so fragile after wearing fake nails that it made it harder to not bite them. Not to mention its embarrassing and often painful to have nail technicians work on your hands when they're so bad. But THIS stuff has made a few big changes for me. For one it grew my nails FAST so it was a feeling of pride and accomplishment quickly which made me not want to bite them and made me stop when i noticed myself biting them and for two I get bad about it when I'm doing something mindless, especially watching TV in the evening, so instead I take time taking care of my nails during that time EXPECIALLY using this serum. I love the little dropper, its satisfying and easier to do when your laying back as opposed to the brush method. After letting the oil soak in I'll often use the sally Hanson nail hardening polish, which gives me something to mess with and pick at the day after. I highly recommend this stuff, especially if you have a nail biting habit or disorder. My nails have NEVER been better. I'm 24 years old and I finally have nails I can be proud of!

I can't believe how this product has weakened my nails. It caused my nails to break off, be dry and crack into layers. My nails are in worse shape than when I started using this "miracle" product. Terrible.
