Frequently Asked Questions

What is Kerasal Nail®?

Kerasal Nail® is a clear, colorless liquid supplied in a plastic tube with a silicone tip applicator to facilitate application to the nail. Kerasal Nail® improves appearance of nails damaged by fungus or psoriasis by normalizing thickness of the nail, reducing discoloration, and hydrating the nail. Kerasal Nail® is free from preservatives and fragrances. The ingredients are fully biodegradable.

How do I treat my nail appearance with Kerasal Nail®?

Apply Kerasal Nail® once daily directly to affected nails, preferably in the evening just before bed time. Hold the point of the tube on the nail. Press lightly on the tube and spread the solution with the point. Cover each nail with a thin layer of the solution. It is important that the solution is also applied under the free edge of any affected nails. After application, allow the nail to dry for a few minutes.

How does Kerasal Nail® work?

Kerasal Nail® improves appearance of discolored and deformed nails resulting from fungal infection or psoriasis, by increasing nail hydration and improving nail surface integrity. It changes the nail's environment to one that fosters beautiful and healthy-looking nails.

Is Kerasal Nail® effective on finger nails as well as toe nails?


How long before I see signs of improvement?

Kerasal Nail® restores healthy appearance of nails with first signs of improvement normally seen after 2 weeks of treatment. However it is recommended to continue to use Kerasal Nail® for 3 – 6 months to achieve satisfactory results.

Can I improve my nail appearance with Kerasal Nail® without being certain that I have nail fungus?

Yes. Kerasal Nail® improves the nail's appearance even if the discoloration or deformation is due to causes other than nail fungus, for example psoriasis.

Are there any side-effects or interactions associated with Kerasal Nail®?

A slight temporary irritation of adjacent skin as well as discoloration of the nail may occur. In certain cases, parts of the nail may loosen/separate from the underlying nail bed, which occasionally leads to detachment of the affected part of the nail. There are no known interactions with the preparation.

Can I use nail polish during the treatment?

No, nail polish prevents absorption of Kerasal Nail® and inhibits the desirable effects.

Is Kerasal Nail® safe for children?

As with many other products, there is limited experience regarding use on children. Since no Kerasal Nail® studies on children have been conducted, we recommend careful use and we encourage consulting your doctor first.

Can Kerasal Nail® be used when pregnant or breastfeeding?

Yes, Kerasal Nail® only works locally.

How long does a tube of Kerasal Nail® last?

Usage depends on the number and size of nails on which Kerasal will be used, but as a guideline, the 10 mL tube lasts for approximately 3 months for up to 3 nails.
