I bought the Clear Gloss treatment because it was on sale and I thought it would be fun to boost my shine for a couple weeks. Well, good thing it was on sale because it didn't do much. There was zero change in the shine of my hair, which is kind of the point of the product...The only reason I gave it even two stars is because, like other hair dyes, it made my hair slightly thicker feeling for a couple days. Though it's now been several days and several shampoos and the awful smell is still sticking around. So to summarize, no shine, awful smell, a little extra body for a few days. Not really worth it.
