GIOVANNIRoot 66 Max Volume Shampoo, 8.5 Fluid Ounce

I have been using this shampoo for the last 3 years and find it to work very well adding body and shine to my fine straight hair. I also have blonde highlights added to my original light brown color and this shampoo really accentuates the blonde giving my hair a great multicolor look!

I love that this has a great lather! It cleanses well and smells good. I use in combination with the conditioner and my hair does seem softer!

I like the way this shampoo gives so much volume to my hair. I will purchase again.

Works great. If you want to clarify your hair just a little bit

My hair thinned out over years of coloring and this shampoo was recommended by my stylist. My hair looks fuller, feels fuller and is very healthy! In my opinion, it is by far THE BEST shampoo out there for thinning hair! Thank You, Giovanni :)

I have thinner curly hair and tried Root66 because it was cruelty free and didn't have all the nasty ingredients in other products. I used it with the Root66 conditioner. After a couple weeks I noticed my hair feeling waxy, stringy and getting more frizz. I did a clarifier, deep conditioner, and went back to my old products and my hair seems to be on the mend. Upon closer examination I noticed that the Root66 products contain Benzyl Alcohol (a curly hair No No) and also regular Alcohol in the ingredients. My bad for not looking more closely before purchasing. I do not recommend this product for thinner curly hair.

too harsh on your hair scalp itches a lot washes out my color too

I have limp, fine hair and this product makes my hair so much fuller ! Great product.
