3 of 5 starsTook this vitamin for four months. Had awful breakouts down my back and on my forehead. I stuck with it because my nails were so brittle, they hurt. Four months on, my nails peel and are still ever so brittle and forehead still has massive breakouts. Hair line too. I wanted this to work so bad. It's important to give it an honest try.Feb 8, 2022Kaelie

5 of 5 starsI have been taking this vitamin supplement for a month and it has greatly improved my nails and hair! Before I took this, my nails would break and split, now they are strong and do not break at the end. When I showered before, chunks of hair would come out, now it is considerably less. I highly recommend this vitamin supplement to anyone that has breakage at the end of their hair and weak nails!Feb 7, 2022Nina

5 of 5 starsYeah! It doing what it said it would! My nails were so thin and brittle, they were weirdly shaped and they would break so easily. But not no more! My nails are long and sturdy and back to a good shape! I'ma keep taking these! Also, my memory is shit from my partying days, so I don't even remember to take them every day, prob closer to like 3 times a week and it's still doing the damn thing! so if i did remember to take them every day i bet they'd be even stronger! so yeah! get you some!Jul 23, 2021Makayla

5 of 5 starsDue to glue on fake nails, my natural nails had become warped and full of deep ridges and waves. Not cute. I started taking these every day (small pill, really nice) and I can literally see the line where my nails started over again. No ridges, just a smooth strong nail. They’ve gotten pretty long and I haven’t needed to cut them yet because of how strong they are. I used to have scaly looking weak nail tips over time and that hasn’t come close to happening either. I’m a fan of Killer Nails.Jul 6, 2021Jordyn

5 of 5 starsI didn’t have trouble with my nails breaking or being brittle until about 4 months ago. I didn’t try anything to help my nails until a month ago when I tried this! I noticed a difference in about 2 weeks of taking one tablet daily. Definitely recommend for anyone with nails that break easilyMay 12, 2021Savanna

5 of 5 starsI don't naturally have brittle nails but my new job has me constantly handling rags with chemicals, so I was noticing they were dry and breaking easier. So I decided to get Killer Nails to see if that would do anything and it actually works! My nails are definitely stronger and I notice way less breakage, so now I can grow them to the length that I want. I noticed my hair is looking healthier at the scalp and I feel like it is growing a little faster. Its hard to tell with my hair because its already so long and its only been 2 months but my baby hairs have for sure gotten longer. Try these out, you'll be impressed!May 4, 2021
