Q: How does this improve the mail without curing the fungus?
submitted by Q - 2 years ago
A: Kerasal has a low pH which stops fungus from growing. It also debrides the keratin debris caused by nail fungus, which exfoliates away the food source of the fungus and improves the discoloration of the nail. Kerasal then conditions the nail so that the nail is smoother, more hydrated and less brittle, making it healthy looking and more resilient. -Kerasal Team

Q: Can this be used in conjunction with the Kerasal Multi Purpose Nail Repair?
submitted by KD - 2 years ago

Worth a try
I vouch for this product because I have been the least consistent like literally only used it two times a day for the first two days after I bought it and then once a day subsequent days if I even remembered to and still saw improvement Granted my case was mild and only had fungal symptoms in the corner on one side of my big toe with a odor you can smell if you scraped underneath it

Kerasal nail care
Kerasal Fungal Nail Renewal is best for improving the look of nails damaged by fungus, especially mild to moderate cases. 👉 For actual fungal eradication, it works best as a companion to medical antifungal treatment, not a standalone cure.

Works well
I am not sure if I had a mild case of fungus however, this fixed the issue. My nail color is back to normal and no more drying and flaking around the toenail. It did take about 2 weeks for the discoloration to go away 100%.

This product does not work. Not even slightly. Unsure where these other reviews came from… but this product is ineffective.

If you have nail fungus, just buy this!
I noticed my big toe had nail fungus, so I tried this treatment. I’ve been applying it twice daily since August 15th, and after just 18 days, my nail looks much better. I thought it would take longer, but it’s already improving.

Good product
I purchased this thinking I had nail fungus. Went to doctor turns out I have an injured dead toe nail. I can’t attest to this product working. I am reviewing that it was easy application and I liked the tube it comes in

DOES NOT TREAT NAIL FUNGUS- ONLY IMPROVES THE LOOK
Just making sure people know that this does NOT treat nail fungus. It only improves the APPEARANCE of the nail that has the fungus. So, if you use this, know that you are not actually getting rid of the nail fungus which is the root of the problem.

It Works!
I never write product reviews but I had to share that this product really does work. I use it in conjunction with Fungi-Cure's spray and my nails look so much better after just a couple weeks. If you've struggled to find a product that actually improves nail appearance, give this one a try. It is a bit pricey but it's less expensive than a trip to the podiatrist and a prescription.

Highly Recommend!!
This is a really great product! Had nail fungus from a nail salon and my toe nails looked awful. I got this product and followed directions. 2 times for first week & then 1 time a day after that. It takes a a couple weeks to start seeing improvement that’s why I waited to write a review. My nails almost look like they use to I’m 2 months in and the fungus is almost completely gone/ grown out.

This works!!!
I tried everything, including a topical prescription from the doctor to get rid of stubborn issue on my baby toe…for over 4 years! I recently took a chance on Kerasal as a final attempt before asking my doctor to prescribe the oral prescription. Kerasal worked!!! My baby toe is now completely normal. HIGHLY recommend!

Works pretty well
I’ve only been using it for a 6 days and I already see a difference! I’ve had this problem for awhile now (like years) and it’s hard to find something that actually is effective. I was hesitant but I just decided to try it out. So far I’d say the fungus has decreased by atleast 20%. I’m gonna go the full 3 months and see the results but so far I’m so satisfied! Miss getting my toes done and hate that I can never wear cute sandals anymore. Would definitely recommend. So far so good!
