Kenra 4NUA Medium Brown Natural Ultra Ash

Kenra 4NUA is a demi-permanent hair colour that delivers a Medium Brown Natural Ultra Ash shade without ammonia. It suits adults with normal hair who want gentle formulation, outstanding coverage and rich colour saturation.

Application and common issues

The colour penetrates the outer coating of each strand and settles in the middle layer where natural pigments reside. Uneven results usually come from skipping the strand test, applying to dirty hair or not timing the development exactly as directed.

Capacity and coverage limits

The 2.05 oz (58.2 g) tube provides enough formula for a single full-head application on average-length hair. Longer or very thick hair may need a second tube, and the demi-permanent formula will gradually fade with repeated washing.

Highlights

  • Ammonia-free formula reduces scalp irritation
  • Medium brown ultra ash tone delivers cool neutral colour
  • Demi-permanent deposit penetrates mid-layer for lasting vibrancy
  • Gentle formulation suits normal hair types
