7nn hair color, a subtle take on the ever-popular red hue, is a semi-permanent shade that combines small amounts of natural or artificial red and orange pigments. It gives the impression of having been naturally sun-kissed.
7nn hair color has increased in popularity in recent years due to its ability to enhance natural highlights and bring out the warmth in a person's skin tone. It is also a relatively low-maintenance option since it fades gradually over time, allowing for a seamless transition back to the natural hair color.
