Kerassentials vs Kerasal: Ingredients, Approach, Price and Results

By Leah CorbinEditor, Kerassentials ReviewUpdated October 21, 20264 min read

The names are close, and people mix them up all the time, but Kerassentials and Kerasal take different approaches to a fungal nail. One is an antifungal oil, the other a gel that improves how a damaged nail looks. Which one you want depends on what you are trying to fix.

The quick comparison

Two different approaches

Kerasal is built to fix how a fungus-damaged nail looks. Its own product page says its urea "softens and thins thick, damaged nail layers," lactic acid "gently exfoliates" and propylene glycol hydrates. The brand describes itself as the doctor-recommended choice "among cosmetic options" for improving the appearance of nails damaged by fungus. It doesn't list an antifungal ingredient in that product.

Kerassentials goes after the fungus as well as the nail. Undecylenic acid is an antifungal the FDA recognizes for skin infections, and tea tree, clove, manuka and lemongrass oils all have antifungal research behind them. The carrier oils, aloe and vitamin E condition the nail and the skin around it. The details are on the Kerassentials ingredients page.

Put simply: Kerasal makes a thick, rough nail look smoother and thinner sooner. Kerassentials is designed to work on the cause while the nail grows out.

Can you use both?

They target different things, so some people pair them: urea gels thin thick nails, and thinner nails let topical oils absorb better. Podiatrists sometimes recommend urea products for exactly this reason. If you combine them, apply them at different times of day and let each one dry fully. Patch test first, since layering products raises the chance of skin irritation.

Dosing and convenience

Kerasal is simpler to keep up after the first week: once a day with a precise silicone tip. Kerassentials asks for four applications a day, which takes more discipline, though each one is quick. If you know you'll struggle with a midday routine, that is worth weighing. Our how-to-use guide has a schedule that makes four a day manageable.

Evidence

Neither product has published head-to-head trials. Urea is well established as a nail softener and is often used alongside antifungals. For Kerassentials, the strongest evidence is for its ingredients: tea tree oil matched clotrimazole in a six-month toenail trial, and the menthol and camphor pair it shares with VapoRub improved 83% of toenails in a 48-week case series.

For context on what prescription treatments achieve, the AAD's treatment guide covers the topical and oral options dermatologists use.

Price and buying

Kerasal is cheaper per tube and you can buy one today at a pharmacy. Kerassentials costs more and comes in packs of two, three or six bottles from its official site, but it brings a 60-day money-back guarantee from the company and ClickBank's order support. See the Kerassentials price page for the full breakdown.

Which should you choose?

Choose Kerassentials if you want a product that targets the fungus with an antifungal active and essential oils, don't mind applying it four times a day, and want a long refund window while you try it.

Choose Kerasal if your main goal is a smoother, thinner, better-looking nail, you want something from a drugstore today, or you prefer a once-a-day routine.

See a doctor if several nails are affected, the nail is painful or lifting, or you have diabetes. MedlinePlus explains the prescription options for more serious infections.

Side effects compared

Kerasal's urea and lactic acid can sting on broken skin and may cause mild irritation around the nail, which is why the brand suggests a precise applicator. It contains no essential oils or nut oils.

Kerassentials' essential oils, especially tea tree and clove, can irritate sensitive skin or trigger an allergy in a small number of people, and its almond and walnut oils matter for anyone with a tree nut allergy. Patch test first. Details are on the Kerassentials side effects page.

A typical case for each

Someone with a big toenail that has turned yellow and thick over a couple of years, with itchy skin between the toes, is a good fit for Kerassentials: they need an antifungal routine for the nail and the surrounding skin, plus filing to thin the nail. Someone whose infection was already treated with a prescription but is left with a rough, ridged, discolored nail may get more from Kerasal, since the goal there is appearance while the nail grows out.

Whichever you start with, give it a fair test: the same nails, the same routine, photos every four weeks, and at least two to three months before you decide.
