BATTLE OF THE DUPES #28: Sally Hansen vs. Sinful Colors

I have many nail polishes and when I was going through and binning a few I noticed two that I thought could possibly be dupes.

PACKAGING (Sally Hansen):

Signature Color Therapy bottle.

PACKAGING (Sinful Colors):

Simple and their typical bottle.

Prepped my nails and used the same base coat. Now so you know when I do a battle of the dupes for nail polish I do it in alphabetical order, left to right, I don't do one hand with one brand and the other hand in another because my right chips more because I use my right hand more often.

Sally Hansen (layer 1): need another coat for sure

Sally Hansen (layer 2): I need to tidy them up but do need another coat

Sally Hansen (layer 3): definitely need to clean it up

Sinful Colors (layer 1): it is very pale.

Sinful Colors (layer 2): it is not a dupe
