The Biolage Age Rejuvenating Shampoo is a great addtion to my daily routine. It leaves my hair feeling soft and looking shiney. I am only 28 years old but have severe nutritional issues so using this has made a huge difference in my hair. It is great for dry or dull looking hair. It doesn't leave your hair feeling greasy like many hydrating shampoo's have proven to do. My stylist suggested this as a good option for my situation. I love the smell it is very relaxing. I have been buying this by the liter and it lasts a very long time. This is not one of those cheap shampoo that you need a whole handful to get your hair clean. You need a very small amount even for thick curly hair like mine. The Omega 3 and lycopene complex that it contains fixes all the issues of my hair. The color of my hair is even brighter and I've been asked if I dyed my hair because it looks so much better. I would suggest this for anyone whose hair is starting to look dull or dry!
