Harlem is the way to go Candy c. i m not too familiar with stores downtown unless you want to go to Sephora on 34th street or 42nd street for the fekkai, lazartigue, rene furterer, kerastase, phytospecific and phytorelaxer you have a great selection for the dominican products and all the good stuff
you can either take the 2 train to 116th street, the bss has a large selection of everything from nexxus to whatever same thing on the same block the CVS Pharmacy got a great selection from Sebastians to vo5 to wella, nioxin, minoval, miss antilles, betty hutton hair pouss plus... to whatever and else you can also head to 125th st (2-3 train to 125th street ) and get everything from nexxus, to dominican products, glovers, aphogee.....
sky s the limit but any duane reade, cvs pharmacy anything carry now hair products for african americans and salons brands as well so anywhere you go even around chinatown i m sure i saw a bss around there oh even brooklyn when you take the a train to jay street got 2 huge bss with a lot of products hard to find. Each time i go to church to the Brooklyn Tabernacle there and i stop i see everything from the huge bottle of mane and tail to any product. Enjoy your stay girl and stock up i know you will
