Goldwell Topchic Permanent Hair Color 2oz vs Goldwell Topchic Hair Color 3NN Dark Brown Extra

Both are the same Goldwell Topchic permanent color in 2 oz tubes, so build and performance are identical: 100% grey coverage, CoolProtect against brassiness, and shades that intermix. The real difference is scope. Product A is the general Topchic line with a wide shade range and a 4.8 rating from 69 buyers, so it suits anyone picking a shade. Product B is one fixed shade, 3NN Dark Brown Extra from The Naturals range, so it only makes sense if that exact color is yours. Buy A unless you already know 3NN is your match.

• Choose the Topchic 2oz if you want the full shade range, need to mix shades for a custom color, or want the version with a track record of buyer ratings.
• Choose the Topchic 3NN if you already know Dark Brown Extra is your shade and you want to restock that single color.
