Forget about leaving here without spending at least $20. If you have a nail-polish fetish so severe that the vast subtle difference in pink from "Ballet Slippers" to "Sugar Daddy" means that you have to buy them both, then this warehouse-in-a-strip-mall is your mecca. You've got $7-a-bottle access to the full lines and most current seasonal offerings from OPI, Essie, and China Glaze. Professional-grade cuticle and callous removers come in every size, starting at $4.95 and up to $40 for the larger containers. Files in every grade, from fine to coarse, are available. So are nail brushes, foot files, and scrapers. There are also two rows the length of an Olympic swimming pool full of hair products — one devoted exclusively to shampoos, conditioners, and styling products and the second to color and permanent solutions. Every shape, size, and style of curler hangs on the back wall, and lightning-fast hair driers and straightening irons are also available. Proprietor Diane Browne is nice, helpful, and as enthused about the full-spectrum color wheel of polish as you undoubtedly are. When a customer complained that she couldn't find "Cherry Pop," a pink-tinted clear polish by Essie, Browne knew it by name and found it quicker than you can spray on that fast-drying topcoat.
