Yellow, thick, crumbly toenails. Itching between the toes. That smell you notice the second you take your shoes off. Toenail fungus is one of those problems people hide for years: sandals stay in the closet, the pool is off-limits, and the creams from the pharmacy never seem to finish the job.
Doctors explain why: nail fungus is stubborn, treatment takes a long time, and many people stop before a healthy nail has fully grown out. Kerassentials was created for exactly this situation, a daily oil you can stick with. Here is everything you need to know.
What Is Kerassentials?
Kerassentials is a topical oil made with a blend of essential oils, minerals and vitamins designed to support healthy-looking nails and skin. You apply it with a brush once a day, after your shower, directly on the nail and the skin around it. The official website shows more than 14,500 customer reviews.
Why Nail Fungus Is So Hard to Beat
Fungus lives under and inside the nail plate, where creams struggle to reach, and it thrives in warm, dark, damp places like the inside of your shoes. Nails also grow slowly, so it can take months for a clear, healthy nail to replace the damaged one. That is why consistency matters more than anything else, and why an oil you apply in 30 seconds a day is easier to stick with than complicated routines.
Kerassentials Ingredients
- Tea tree oil: the best-known natural antifungal oil, studied for decades for nail and skin fungus.
- Undecylenic acid: a fatty acid that is actually used as an active ingredient in over-the-counter antifungal products.
- Lavender oil: studied in the lab for antifungal activity and used to protect nail keratin.
- Lemongrass oil: an essential oil with strong antifungal properties in lab studies.
- Organic flaxseed oil and almond oil: nourishing oils that soften the skin and support the nail bed.
- Aloe vera: soothes and moisturizes irritated skin.
- Tocopheryl acetate (vitamin E): protects the skin and helps the oils penetrate.
Our take: having both tea tree oil and undecylenic acid in the same formula is a big plus, since these are two of the most researched natural ingredients for fungus.
How to Use Kerassentials (Step by Step)
- Shower and dry your feet completely, especially between the toes.
- Use the brush to apply the oil on each affected nail, under the tip and on the skin around it.
- Let it absorb for a minute before putting on socks.
- Repeat every day. Keep going until a fully healthy nail has grown out.
Pro tips that make a difference: change socks daily, let your shoes dry out between uses, never share nail clippers, and wear flip-flops in public showers and pools.

What Results Can You Expect?
The manufacturer says many people notice that the itching is soothed and the nails look more alive in the first weeks. Remember that the damaged part of a nail does not "turn back" to normal: what you are looking for is a clear, healthy nail growing from the base. Toenails grow slowly, so the full change takes months. That is exactly why most people choose the 6-bottle package, so they do not stop halfway.
