This specially crafted foam for color-treated hair is a quantum leap from stiff, sticky, crispy old-fashioned mousse formulas, this “smart foam” uses rosins (a natural rubber-like substance derived from trees) not the traditional resins (stiff, acrylic polymer) to give hair soft, flexible texture to make styling easier AND to protect against breakage. Shake well. Hold can upside down and dispense into palm. Apply evenly to damp hair and style as usual.
