Nail-Aid Biotin Ultimate Strength - Nail Treatment & Strengthener - Clear, 0.55 Fl Oz (08873)

It works! My nails were damaged from months of gel manicures and they had that odd bump. Weeks 1 and 2: nails crack and chipped as they grew so I had to file them to the quick. I was frustrated but decided to keep at it. Week 3: old nails were fully gone and new nail growth was great. Firm with no breaking. Week 4: even longer, healthy nails. I’m ver pleased with the results. I’m going to use this as an under base coat with my next manicure. It’s a great product!

This stuff is amazing! My nails were getting very thin from my stylist filing down my nails too much to get the dip and gel off. I just bought this on Prime Day (just over a week ago) and I can already notice a difference. My nails that were thin, are definitely stronger. My nails are growing out faster and where they are growing in, they are thicker than before as well. If you decide to give your nails a break from gel/dip, definitely look into getting this for that break. If you just use this, it will flake off around 3 days in but that's because your nail essentially sucked out all of the good stuff on the bad parts of your nail. I was amazed to see the difference it made.

I have been using this for about a week and a half. I do think my nails are getting stronger, but I do find it to be flaky within a day or two after application. Technically the instructions say to remove and reapply every few days, but if you’re not able to do that then it gets flaky.

This nail strengthener applies easily and seems to be working, as described, with no offensive odor. It keeps fragile nails protected. I recommend this product.

This is first nail product that finally produced actual finger nails that grow instead of chipping and breaking. Has stopped the separating layers and weak nails as well. Highly, highly recommend. I remove and reapply every 2-3 days to make sure my nails stay strong. I'm 82 and have never had nails like this has produced. Highly recommend and hope others find it as helpful as I have.

I’ve been using this nail treatment for a few weeks. It goes on smoothly and dries fairly quickly, which is great. It gives my nails a nice clear shine and a slightly stronger feel. However, I haven’t noticed a significant improvement in nail growth or reduction in breakage. It might work better with longer use, but for the price, I was expecting more visible results.

I do not play about nails, I’m always looking for ways to make them stronger, healthier & longer !! This nail biotin is the best thing ever!! Immediately after polishing my nails with them, they instantly were so strong and not flimsy anymore. Also only took less than 10 seconds to completely dry them, which is so impressive. I love that they left my nails so shiny for daysss !!! Also love that it acts as actual clear polish, so it was easy to take off with simple nail polish remover. I’m going to try and apply this every 4-5 days to make my nails stronger and longer. I love this so much ! Will be buying the bigger bottle and will be buying more!!

I seriously damaged the base of my thump nail with a knife. It truly is unsightly as it grows out. This product with 2 or 3 coats has filled in all the grooves and makes that nail feel even & slick. I have used it on all my nails and the product is longlasting and resistent to peeling.
