    Love this! I have weak nails, that tend to break and chip at the ends, making it hard to wear nail polish. The chipping goes away when I take Killer Nails!

    My whole life I've had a bad habit of either nail biting or picking skin and ever since I was introduced to HUM (March 2020), no lie, my nails are completely restructured. And the little amount of time it took was amazing. I definitely won't change up this one. I notice my hair grows pretty quick as well. But the change in my nails is amazing. I can FINALLY get a REAL gel manicure without having to add a tip or add acrylic on my nails to make them last longer or stress about breaking within 2 weeks. I LOVE this product.

    Legit. Love. I have little patience for nail growth and these surpassed all expectations and showed a lot of progress in a short amount of time!

    It's ok, not magnificent. Not sure if I was seeing results or imagining it.

    I have brittle and thin nails as well as super fine hair. Both need lots of lovin! This product did a great job! I decided after a month of just Biotin that I needed something else, like Hair Sweet Hair. I'm thankful for the Killer Nails boost for the time I was using it!

    I love this so much. It’s the only biotin product I have found the really helps my nails grow stronger and stop peeling. It takes about a month to see real results but it’s definitely worth it.

    I started taking killer nails because I loved Skin Squad, and my nails had been breaking really easily. It definitely worked a bit, my nails seem stronger and the roots of my hair are soft. However, my nails still split easily and my hair breaks easily as well. More importantly, this was TERRIBLE for my skin. I have hormonal acne, and I started getting cystic acne on my chin and cheeks around the same time as I started this. I chalked it up to mask wearing, but my roommate told me she'd read that biotin was bad for acne in those exact areas of the face. I stopped taking it, and within a week my skin cleared up. Maybe the 1 star is too harsh, given that it did have some benefit for my hair and nails, but I wish I'd known that this could cancel out the really positive effects that Skin Squad had for my face, which the reason I started taking HUM supplements in the first place.

    I’ve been using killer nails since the lockdown first started in Mar/April — and OMG. In the 2”31 years of living I have neverrrrr been so happy with the strength and length of my nails. Seriously the BEST vitamin I have taken for my nails. It’s helped soooo much. I won’t ever stop taking these.

    Before I had very week nails that would not grow and were brittle. I have been taking this for a few months and have noticed my nails are stronger and thicker. They still break as they are growing out but its an improvement!! Very happy I have not noticed anything with my hair
