About Revlon Professional
Revlon Professional is the salon-trade arm of the long-running American beauty house — founded in 1932 by Charles Revson, his brother Joseph and chemist Charles Lachman. The Color Excel Creme Gel line within Revlonissimo combines a creamy texture with the easy spread of a gel — focused on long-wearing, ammonia-free colour with built-in conditioning.
Key benefits
- Ammonia-free, tone-on-tone demi-permanent hair colour — gentler than a permanent.
- Cream-gel texture for smooth, even application.
- Long-lasting result with built-in conditioners for hair shine and softness.
- Shade 66.40 is an Intense Copper — the "66" denotes a double-deposit dark blonde lift level for stronger pigment, with a "4" copper reflect for high-impact warmth.
- C5 molecule technology delivers intensified colour with added durability.
Who it's for
Anyone wanting a bold, statement copper finish — particularly suited to brunette and blonde bases looking to shift into rich, warm copper. Best applied by an experienced colourist or with a clear understanding of professional colour mixing.
