Goldwell Topchic Hair Color Coloration (Tube) 7NN Mid Blonde - Extra vs Goldwell Topchic Permanent Hair Color 2oz

Both are the same Goldwell Topchic permanent color in a 2 oz tube, so the formula, 100% gray coverage and 30-minute processing are identical. The real difference is the shade: A is 7NN Mid Blonde Extra, a double-neutral blonde, while B is sold as an open shade range you pick at checkout. Buy A if you already know you want that specific mid-blonde neutral; buy B if you need a different shade or want to intermix. Owners praise coverage and longevity on both; the recurring complaints are an occasional expired tube and unpredictable results on white hair.

• Choose the Goldwell Topchic 7NN Mid Blonde Extra if you want a double-neutral mid blonde for full gray coverage and low warmth, and you already know this shade suits you.
• Choose the Goldwell Topchic 2 oz if you need a different Topchic shade, want to mix shades for a custom tone, or prefer to pick the exact level and reflect at checkout.
