About three weeks ago I purchased Kevin Murphy shampoo and treatment conditioner from the Blonde Angel Range.
They are honestly amazing for taking away that brassy blonde look and my hair feels super fresh and hydrated after use. These are also paraben free and are a vibrant blue colour with colour enhancers that really do revive and brighten blonde hair. I purchased mine from http://www.shampoo.ie. You can also look at the website http://kevinmurphy.com.au/product/blonde-angel/
Here is a detailed list of key ingredients from the website.
Sunflower Seed Extracts
Sunflower Seed Extracts avoid the stripping of colour from the hair. These extracts act as a natural sunscreen that guard against colour fade and brassiness.
Olive Oil Extracts
Hydrates, restores and repairs. A natural antioxidant; it promotes shine and elasticity. It is rich in biotin, niacin, Vitamins A and E.
