You will find real healing!
This is a really good product! Apply it every day and your nails get stronger, no longer split or peal. My nails are in better shape than before I injured them wearing the fake nails you get at the salon.

FINALLY~ a treatment that works!!
This product is likely the 15th or 16th one I've tried that makes the same claim, which is that it will strengthen and heal nails~ yet this the ONLY ONE THAT WORKS, in my experience. I am beyond thrilled to finally have fingernails that are not peeling & splitting, and it's all due to this wonderful product! I noticed a difference after the first application, and have now used it for five days, once a day before bed. There is a strong odor that dissipates within a minute or two, and leaves no funky smell, texture, tint or residue~ YAY! Thank you ePhD, from the bottom of my heart. =)

Strong healthier nails
I’ve tried everything, from supplements to professional nail treatments. My nails are ridged and have always broken easily. EPhD brought my nails from damaged and splitting to thicker and stronger in about 3 weeks. It’s not just co wring up the problems. They seem healthy!

I Finally Have Nails!!
This nail treatment has really worked!! I have had trouble getting my nails to grow even close to the end of my fingertips for all 73-years of my life! I have tried alllll kinds of treatments, polishes, pills, etc over the years but none of them did for my nails what this nail treatment has done!!! The only draw back is, if I understand the directions correctly, I can't use any colored polish - at least not for very long. The bottle says to "apply daily to bare nail" so once you polish the nails, they are no longer 'bare' for the treatment to work on them. But, for a special occasion, I would polish them, remove the polish after a day or so and then go back to the treatment on bare nails. BUT, at least I finally have nails!!! One reviewer said they couldn't see the product in the opaque bottle & thought it must not have much in it but I have been using the treatment daily since purchasing in early September and it is now almost December 1 but I haven't run out yet. After accidentally tapping a hard surface with a nail, I have had a couple break over these months. In those instances, I put the product on the bottom side of the broken nail to help strengthen it as it grew out and it matched the other nail lengths again in no time.

It Really Works
Desperate to find a remedy for my brittle, weak, and constantly splitting nails I took a chance and tried this product. To my surprise, it is actually helping. I have been using it for about a month now applying it every night on bare nails. It dries rapidly and there is no build up. For the first time in I don't know how long, my nails have not been splitting. That I can use it as a base coat under nail polish, if I choose to, is a plus. For me, it really works and is comparably priced.

Didn’t work for me
Felt good on my nails but didn’t do much of anything else. Didn’t see any improvement in growth, strength or peeling

Stuck with it ... Amazing!
I just purchased a second bottle of this stuff. I really wasn't sure about it at first, but I stuck with it and it turned out to be amazing. Before using it, my nails were brittle and I was constantly cutting or filing them. Now they are a beautiful natural length...and they don't break when I hit them on something! I did use it daily at first, but once most of the damage was mitigated I now use it every other day or so. I know it doesn't seem like there's a ton in the bottle, but a little bit goes a very long way. Very, very happy with this product.

This really works
I have taken a while to review this, I wanted to make sure it continued to work. I stupidly removed my gel nails at home and wrecked my own nails. This has worked brilliantly to repair the damage and condition my nails. I would definitely use again..

Im picky, but I love this.
After a few uses this stuff actually works! My nails are stronger, less cracking/splitting and not nearly as dry after just a few uses. They look better too. I would highly recommend this to anyone after gel nails, or with weak or brittle nails. I love how quickly it absorbs, no grease, no mess, no stickiness. It’s not like other “polishes” ..I would describe it as the most moisturizing treatment my nails have ever experienced.

If you tried everything and your nails keep splitting
Not like any other nail care I have ever used. This is more like an oil that literally sinks into your nail. I have used it for 2 weeks now and the annoying splitting of both my indexes and thumbs has stopped! I leave the bottle on my coffee table and I put coat after coat while I watch Netflix keeping in mind to not use my hands too much while the product penetrates my nails. It’s a process but so far, I am pleased with this product. It was actually recommended to me by ChatGPT 🤭
