Nanogen Root Concealer - Black - 4g

The formula is designed to be gentle, but if you have a known history of scalp sensitivities, it is recommended to perform a small patch test before full application.

While the formula is sweat-resistant, it is a surface-level powder. It is best to avoid heavy pressure against fabrics, though most users find it stays secure if not excessively rubbed.

It is sweat-resistant, meaning it holds up well during daily activities and light humidity, but it is not intended to be used while swimming or during heavy rainfall.

Yes, the Black shade is highly pigmented and typically blends well with very dark brown and jet-black hair tones.

Longevity depends on the frequency of use and the size of the area being covered, but most users find a single compact lasts several weeks for regular root touch-ups.

Ensure hair is completely dry before application and try applying it after your styling products have fully set.

Apply the product in smaller, light layers rather than one heavy application and use the included tool to blend it out.

Avoid touching or brushing the treated area throughout the day, as friction can disturb the fibers.
