Karma Naturals Deep Nutrition Nail Strengthener – Ridge Filler, Nail Hardener & Growth Booster for Thin or Damaged Nails (0.43 FL oz)

I went cruelty free a couple years ago and although this was easy for most makeup and beauty items, the struggle has been real for nail polish. I was a die hard OPI fan and have been having a terrible time finding quality nail polish since giving them up.I have literally had polishes that were "recommended" by people's reviews on Amazon that just peeled off the first day you used them. Terrible.This is a LIFE SAVER nail polish. I have the weakest worse nails. They literally rip off every time i try to grow them out! It's also worse because I'm an ex nail biter so I have a tendency to mess with my fingers with my teeth a lot. Usually, I use some nail polish to keep them "strong" enough to not ruin them with my mouth. But all the cruelty free polishes were so weak. This polish, the reviews I read were all true. It took a couple weeks. The first coat you can tell is at least a decent polish. Seems pretty normal compared to regular polishes. Then the longer i used it, a few weeks in, I noticed that my nails were rock hard (for me at least, they're usually all bendy). I kept them "short" by filing them for a few weeks trying to let them really build up some strength before letting them start to go long. Now, they're really nice nails. They are sturdy, hard to the tap on the table, and the shade of this polish is pretty much clear with a hint of baby pink to it so it actually makes your nails look better, less yellow tinted. I cannot say enough great things about this polish. It has allowed me to have strong long nails for the first time in my life without having to get gel or powder nails at the salon. I highly recommend trying this polish, it is worth the expensive price.

I have been battling splitting and peeling nails for several months and have tried several products billed as "nail strengthener" with little success. My first mistake was to use acetone nail polish remover to strip off one of these products that suggested using one coat per day for a week, then stripping and starting over with clean nails. I believe the acetone really wrecked my already weak nails. I tried Karma Naturals soy-based polish remover and my nails started improving immediately. So I tried their deep nutrition nail strengthening polish and I knew I was on the right track. Unlike other products (like OPI Nail Envy), this polish stays on and looks natural. It has a very slight peachy pink tint that looks neutral on my fingers. It hides the split and peeling areas so they are pretty much undetectable. I'm also using rubber gloves when I do dishes or clean, which is helping as well. I will update after I have used Karma Naturals for a month and see how I've progressed. For now, two thumbs up! [Update 3 weeks later: I'm using either the "Deep Nutrition" polish or the 2-in-1 base and top coat. I still have peeling on two nails, but I'm cutting them short and using a gentle emery board/nail buffer. I only use Karma Naturals remover--you need to wash hands after using because it is very oily--and my nails have improved dramatically. I believe all the peeling and splitting will be gone soon. All ripples have disappeared already. I love this stuff!]

Stays on without chipping. . Have used this for many years.

I like the color but I have not used it long enough to see if it's helping my nails get stronger. I see that it's peeling off quite fast so I have to redo it often.

It claims to be less toxic/ non-toxic, but smells like any other nail polish, so that’s a little concerning. I wish it had zero opacity, because putting a second coat on after the first coat without removing the first coat (as per instructions) creates a weird, streaky, uneven layer, and it’s quite ugly in my opinion. I’m fairly low-maintenance (thus the unkempt cuticles), but I also want my nails to look tidy and somewhat maintained, so a product that requires multiple coats and a lot of fussing to make it even is not going to work for me. The photos show 3 coats, and they are still uneven. It is entirely possible that my technique leaves something to be desired, and yet I don’t want a product that requires advanced technique to make it look decent. It looks fine with a single coat on.Update: my nail chipped and broke even with 3 coats of this polish on, and I would return it, but it is not eligible for returns. 😕

Nice product no odor see a slight improvement in nail growthWould buy again

Great product!! Using fora couple of weeks and my nails are getting stronger!!

Honestly - meh. I mean, the color and coverage I like, but as far as "deep nutrition" -- it isn't improving the health of my nails. They are still thin and splitting.
