Cerafill Dense Fx Hair Diameter Thickening Treatment, 4.2 Oz

First of all, I was shocked at the price of this Cerafill Dense Fx treatment, but since I have such fine, thin hair, I went ahead and ordered 2 bottles. When it arrived it said there were 4.2 oz in teach bottle, but when I looked at it, I saw that there was less, because I measured it with other bottles of Cerafill that are new and II have not used. yet. There was at least 1/2 oz under that amount in each bottle. I was disappointed that I paid so much for it and they didn't even put the full 4.2 oz in each bottle.

this appears to be a knock off. it looks like the real thing but the container was different than the one I purchased from my salon.
