★★★★★ Nonyx Nail Gel

Xenna: Nonyx Nail Gel, Exfoliant of Keratin Debris, Foot Care, 4 Oz I bought this because it really works … at Walmart,…If your toenails are thick and yellow, then using this works. It does take a while, but it tells you that. Once your nails aren't thick and yellow anymore, you do have to use it 2 or 3 times a week to maintain.

I was skeptical at first thinking this product would not work as advertised. I was very pleasantly surprised to realize that it work perfectly! My nails have never looked better. Love this product!

I think these are great products.  I am an ortho PA and have many patients that have callous build up after wearing a cast for several weeks to month.  I have patients with discolored nails as well.  I do believe in the  product and it really works

Seeing progress!

I tried another brand … but I have been using this item for a month and have started notable changes. This is in regard to lifted toenail areas … and reattaching to the nail. I haven't had enough use to note thickness changes yet. Also, this bottle was more expensive by a couple of dollars but I have used less than a quarter of a bottle in a month and I apply it liberally twice a day.. The label states it can last 6 months. So it is a great savings considering most other treatments are a month’s use per bottle.

What is keratin debris?

Keratin debris is the white, yellow or brown hard, granular build-up that you see on or under your toenail or fingernail. Keratin debris build-up can cause your nail to separate from the nail bed.

How long will it take to get out the keratin debris?

About 3 to 12 months depending on how fast your nail grows. You'll start to see improvement in about 4 to 5 weeks. Try to use NonyX twice a day, especially after bathing.

What if my nails look no different after a month of using NonyX Nail Gel?

Be patient and be sure you are applying the drop of gel to the surface and underneath the tips of discolored nails. Remember to make the HABIT of using NonyX DAILY.

You can also use the Band-Aid® method to speed things up -

Band-Aid® Method

  • Apply gel to your nail and under the nail tip.
  • Place a fresh Band-Aid® over the nail area.
  • NonyX works faster if the gel stays moist on your nail.
  • Avoid getting the gel on your skin, however.
  • Remove the Band-Aid® before bathing.
  • After bathing, pat your nail dry, add more NonyX and repeat with a fresh Band-Aid®.
  • If you do not bath frequently, then change the Band-Aid® every other day.
  • Weekly, use your manicure tool to remove any additional softened keratin debris, being sure to wipe it down with some additional NonyX Nail Gel afterwards to keep it clean.

Can I use NonyX on my child's nails?

You can use NonyX on your child if they are old enough (5 or older) to understand not to put their toenails or fingernails near their eyes or get the gel in their eyes, as NonyX is an eye irritant. You should apply the gel yourself and keep it out of reach of your child when not in use. NonyX is non-toxic.

What is ethanoic acid?

The ethanoic acid in NonyX is the exfoliant of keratin debris. Ehtanoic acid used in NonyX breaks down only the keratin debris. It has no effect on your normal nail plate. The ethanoic acid in NonyX Nail Gel is made from fermented corn and wheat with water added.

Can nail color be used while using NonyX?

Nonyx Nail Gel will not penetrate nail polish. However, you can apply Nonyx as follows under nail polish: Apply a smooth coat of gel to bare nails, let dry then polish. Apply gel under nail tips daily, if possible. Repeat with every change of polish, change polish more frequently than usual and scrape out softened keratin debris weekly once it is softened.
