Advertentie

Gentle Care with ODS Technology

iNOA Supreme utilizes the Oil Delivery System (ODS). This oil-based formula replaces ammonia, helping to preserve the hair's natural protective layer while keeping the scalp comfortable during application. Additionally, you won't have to deal with the strong, pungent smell typical of traditional dyes.

Tailored for Grey Coverage and Shine

The Supreme line is specifically engineered for hair with a high percentage of grey. Shade 4.25 (a deep, warm brown with mahogany and iridescent tones) not only covers greys perfectly but also adds visual density and a healthy, vibrant shine, avoiding a flat, artificial look.

Frequently asked questions

Do I need to buy anything else?

Yes, this is a professional color tube. You will need to purchase an iNOA Oxydant (developer) separately, along with a mixing bowl and applicator brush.

Is this dye suitable for a sensitive scalp?

Yes, because the formula is ammonia-free and oil-based, it is significantly gentler and less likely to cause scalp irritation compared to traditional hair dyes.

How much product is in the tube?

The tube contains 60 ml of hair color, which is typically enough for one full application on short to medium hair, or multiple root touch-ups.
