The formula for this mascara is pretty good if you prefer volume over length; there’s lots of volume, hardly any clumps, and rich colour. I average at 12 hours wear per day, and the mascara has never flaked on me. However; I didn’t like the absence of any lash lengthening, and that this mascara can’t hold any curl.
There doesn’t seem to be anything special about the design of the brush - regular bristles and standard shape - but for some reason I always end up with mascara on my lids and browbone,
There’s not much to say for Thick & Fast - it’s not a bad mascara, just not one that stood out for me. I don’t feel as though I can recommend this product to anybody at the end of the day, as so many mascaras at this price point perform better.
