L'Oreal Professionnel DIA cticateur 15 Vol (4.5%) Gentle Hair Color Developer for Professional & Home Use - 1000ml/33.81 oz
Fifteen volume is the middle setting in the Dia range, and it exists for the jobs sitting between a gloss and a proper colour change. Enough strength to shift a tone noticeably, not so much that you lose track of what the natural base is doing underneath.
Ammonia free, demi-permanent, mixed with DIA Light or DIA Richesse. Typical use is refreshing colour that has faded unevenly, blending grey without committing to permanent coverage, or putting shine back into hair that looks dull rather than the wrong colour.
Colour deposit stays uniform through the section, which is the difference between a demi-permanent that looks deliberate and one that looks like it ran out halfway down.
Fifteen volume is the strength people underuse. It handles a surprising share of a colour column once you stop reaching for permanent by reflex. 1000ml (33.81 oz).

Application tips
Runs alongside DIA Light and DIA Richesse at the ratio printed on the tube. Nothing else in the bowl.
Apply to dry, unwashed hair for a refresh, or to towel-dried hair for a gloss, depending on the service. Take the roots first where the grey is heaviest, then carry it down the lengths for the last few minutes. Emulsify with a little water at the basin before rinsing so the colour lifts away cleanly.
Results
Tone shifts noticeably without the base changing underneath. A faded mid-length comes back to the shade it was meant to be, and the regrowth line stops announcing itself.
Grey blends into the surrounding colour rather than being covered over, which ages far better as it grows. Hair comes out shinier than it went in, because a demi-permanent sits in the cuticle instead of forcing it open. Fade is gradual, so the next appointment is not urgent.
