Revlon Professional Color Excel in shade 7.41 Dark Chestnut Ash Blonde is an ammonia-free, tone-on-tone colour in a 70ml size. It is a demi-permanent colour that gently deposits tone without lifting, suited to blending first greys and refreshing faded lengths. The gentle formula is designed to leave hair conditioned and shiny, with a natural-looking finish. It gives a soft, gradual fade with no harsh regrowth line.
