Is Funginix safe to use?

Yes. Funginix contains 10% undecylenic acid, a commonly used over-the-counter antifungal ingredient. If you are pregnant, nursing, diabetic, or have a condition affecting circulation, consult your doctor before use.

How do I use Funginix?

Apply Funginix twice daily, morning and night, to clean, dry nails and surrounding skin. Use the brush to apply a thin layer to the affected nail, including the cuticle and under the nail edge. Keep nails trimmed and use consistently for best results.

How long does it take for Funginix to work?

Results vary depending on the severity of the infection. Some users may notice improvement within a few weeks as healthier nail growth appears. Full results can take several weeks to months, as the damaged nail needs to grow out completely.

What is your return policy?

Every Funginix purchase is backed by our 90-day money-back guarantee. If you're not completely satisfied for any reason, contact us within 90 days of purchase for a full refund. No hassle, no questions asked.

How can I contact customer service?

You can reach our customer service team at customerservice@sisquochealthcare.com or through the Contact Us page. We typically respond within 1 business day.

Can Funginix be used on fingernails as well as toenails?

Yes. While Funginix is formulated with toenails in mind, it can be appliedto fingernails affected by fungal infection using the sametwice-daily method. Apply to the cuticle and skin around eachaffected nail and allow to absorb fully.

How is Funginix different from Lamisil or other antifungal treatments?

Most OTC topical antifungals use tolnaftate or clotrimazole as theiractive ingredient. Funginix uses 10% Undecylenic Acid — a fattyacid derived from castor oil with strong antifungal properties and along safety record. Funginix also combines this with 14 additionalbotanical ingredients (tea tree, clove, aloe, lavender, Vitamin E)that support nail health and soothe the surrounding skin duringtreatment. Oral Lamisil (terbinafine) requires a prescription andcarries systemic side effects; Funginix is applied topically andformulated for daily OTC use.

What causes toenail fungus to keep coming back?

Recurrence is common because toenail fungus thrives in warm, moist environments.Common re-infection sources include contaminated footwear, sharedshowers or locker rooms, and damp socks. To reduce recurrence:disinfect old shoes, use moisture-wicking socks, keep feet dry andwell-ventilated, and continue Funginix for the full 3-month courseeven after visible improvement. People with diabetes or poorcirculation are at higher risk for recurrence and should take extrapreventive care.

How do I know if my nail fungus is getting better?

The most reliable sign of improvement is clear, healthy nail growing in at the base (near the cuticle). Because nails grow slowly — roughly 1.5mm per month for toenails — this process takes time.The existing discolored, thickened nail will still be present and must grow out naturally. Do not stop treatment when you see early improvement; continue through the full course for lasting results.

best nail biting product I've ever tried

Works

I was skeptical at first, but I have an 8 year old nail biter so figured I would give this a go. It is easy to apply to the fingernails and has a bitter taste if they try to bit their nails. Within a week of using this product my daughter stopped biting her fingernails. This is great for any nail biters!

Best I've tried yet .

This looks like it will be a good resolution for people who bite their nails,but what about people who use their hand to pick their nail like I do. Preliminary it does work. The smell is bad out of the bottle,but dissipates after drying. The bitter taste is definitely a deterrent. Minus a star for the deformed application brush.

I stopped bitten instantly!!!

This stuff taste so nasty that you wouldn't even want to put it near your mouth or your nose. It will help you stop biting your nails and stop eating food.. As a nail biter I have not bitten my nails in two weeks. Highly recommend!

Great to stop nail biting!

Great quality product at a good price. Very durable and long lasting product that is bitter tasting to deter you from biting your fingernails. Stays on throughout multiple handwashings. Easy to apply.
