Loreal INOA Parts Shade 60GM 4.20

The L’Oréal Professionnel INOA 4.20 Extra Burgundy Brown 60g is a permanent professional hair color created for anyone looking for a deep brunette result with elegant burgundy reflects. Rather than producing a flat brown finish, the INOA 4.20 shade adds noticeable reddish-burgundy dimension to create richer and more expressive color.

Powered by L’Oréal Professionnel's patented Oil Delivery System technology, INOA uses an oil-rich coloring system to support efficient color delivery inside the hair. The formula contains no ammonia, helping provide a more comfortable coloring service without the strong ammonia odor traditionally associated with many permanent hair colors.

One of the key advantages of L’Oréal INOA shade 4.20 is its ability to combine fashion color with professional grey coverage. Depending on the formulation and application technique used by the colorist, INOA can provide up to 100% grey coverage, making the shade suitable for clients who want to cover greys while maintaining a rich, dimensional brunette appearance.

The Extra Burgundy Brown tone sits within the darker brunette family but introduces visible burgundy character. This makes INOA 4.20 a strong option for people who want something warmer and more distinctive than standard brown without moving into an overly bright red shade.

The professional formula is also designed to provide high-impact, long-lasting color and enhanced shine. Hair appears glossy and polished after coloring, helping the burgundy-brown reflects look more dimensional under different lighting conditions.

For predictable professional results, L’Oréal INOA ammonia free hair color 4.20 should be combined with INOA Oxydant in the recommended 1:1 mixing ratio. The standard development time is 35 minutes, although the developer strength and exact color formulation should be selected according to the client's starting hair level, percentage of white hair and desired result.

Whether the goal is full-head permanent color, grey coverage or refreshing a deep brunette look with burgundy dimension, L’Oréal Professionnel INOA 4.20 Extra Burgundy Brown offers a professional solution combining intense color, shine and an ammonia-free coloring experience.
