The L'Oréal Professionnel Blond Studio 20 Vol Oil Developer is the 6% activator designed for balanced lift with the Blond Studio system. The oil-enriched cream formula keeps mixing smooth and application even, ideal for colourists who want predictable performance without compromising on hair condition.
At 20 Vol, this is the all-rounder developer in the Blond Studio range, strong enough for solid lift on most natural bases but gentle enough for sensitive scalps and previously coloured hair. We reach for the 20 Vol regularly in the Codsall salon when we want clean lift without going to the maximum strength of the 30 Vol. The oil enrichment helps the lightener spread evenly and gives a useful working window before the mix starts to dry out. Safe for scalp, lengths and ends with a maximum development time of 50 minutes.
The 1000ml salon professional size is built for high-volume colour work. If the Blond Studio system is part of your regular service menu, the 20 Vol is one of the most versatile developers in the range and worth keeping in steady stock.
