ePhD Bond Repair Nail Treatment, Nail Repair that Strengthens, Restores & Rebuilds Brittle Nails, Strengthens from Within, Formula for Damaged, or Post-Gel Nails, Use Alone or as a Polish Base

I first read about ePhD in an article in Real Simple Magazine "Smart Beauty Awards for 2025". I was further convinced to try this product by the positive reviews on Amazon. I've been using the product for nearly a week and the results are amazing, it really works! My nails have always been thin and brittle and were further damaged by having gel nails. They are noticeably stronger and healthier looking. They haven't looked this good for decades. I have 2 nails that have splits that have never grown out. I have high hopes that ePhD will mend the splits. This product is well worth the $20 investment.

I would’ve given this 5 stars —- but the brush is awfully cheap. For the price, can’t you do better? Otherwise the product works great for me. Noticeably stronger nails.

It's easy to apply and dries quickly. I does have a strong smell when you open the bottle but thankfully the smell dissipates quickly. I've been using it daily for two weeks and my nails are noticeably harder.

I've seen significant improvement of my nail strength since using this product. After years of using dip powder and having the drill and acetone used to remove it, I decided it was time for a break to let my nails heal. They were thin, peeling and had ridges. I've been using this product for 2 weeks and my nails are stronger and they are growing out the ridges. I highly recommend.

Just used it once so far. But I loved the fact that it is not a polish. But this product penetrates the nail to enhance the natural nail strength. Then you can just polish over

I’m going to start with 3 stars and may update over time.It’s a costly product. If it works, then it will be worth it.The bottle was plastic wrapped, meaning no way for any contents to spill in transit.However as others have said, there is not much product in the bottle.Since the bottle is white it’s not like you can see that. I had to angle in with a light to see that there is very little in this bottle.The reason I questioned what was inside is because it’s nearly dry on the brush when it comes out. I had to apply multiple coats tipping the bottle each time.Also it says for use with nail polish on the description here on this listing. But on the bottle says to use under. Yet to also use once a day to a bare nail.I got this so that I could apply first, do my base coat, do my polish and use on top until time to repaint my nails. Using daily on bare nails will only work for people that don’t polish.I hide my damaged nails under polish. So time will tell. Not sure I’ll buy again since the bottle isn’t full and very dry when it does come out.

So far love the product- seems to be working! My nails haven’t been growing in 2 years since have a gel manicure with tips. My only complaint/problem is with the brush.- it separates and seems to go all over the place!

Since it is getting into the summer season and my toe nails looked so bad . I did not want to wear flip flopsI decided I had to do something and started using this on my toes and finger nails around 6 to 8 weeks ago.My toe nails had fungus and looked really bad . what I did notice is this product made my nails stronger and harder .week by week my nails started to look better and get harder. now they look great and the fungus is gone . I personally think it is because my nails are healthy now and fungus can not invade . No matter what they look great and I can wear flip flops again
