The seller names three plant oils: rosemary oil, castor oil and green tea oil. Here's what each one is, what isn't disclosed, and how to use it safely.

What the seller doesn't disclose

If a full ingredient list matters to you (for example because of allergies), check the label or ask the seller's support (phone and live chat are listed) before using it.

Possible side effects

The seller doesn't publish a side-effect list. With plant oils applied to the skin, the main thing to watch for is irritation or an allergic reaction:

Is WellaNail a medicine?

No. It's sold as a cosmetic nail-care oil. We found no clinical study of WellaNail itself, and plant oils are not a substitute for diagnosis or treatment of a fungal infection. For a nail that's painful, thick or spreading, see a pharmacist or doctor.

In short: a simple blend built around familiar cosmetic oils, applied twice a day. Fine for a nail-care routine – just patch-test first and don't expect medicine.
