Buy Bigen Repicolor 5NA Deep Natural Brown Hair Dye – 5NA vs 5N: The Deepest Shade
Both 5NA and 5N sit at the deeper end of the Repicolor range. However, there is a clear distinction between them. The Bigen 5NA deep brown dye delivers a more naturally blended, softly deep finish. It has a subtle warmth that makes it look genuinely natural rather than solidly dyed. Moreover, this makes it ideal for those with very dark or black natural hair. In contrast, the Bigen Repicolor 5N Natural Brown is slightly less deep with a cleaner brown tone. Therefore, if you want the most naturally dark, seamlessly blended finish available in the Repicolor range, shade 5NA is your answer. Furthermore, both shades share the same trusted six-free, zero-odor formula.
