Chroma, a new hair salon, will be opening by the end of June at 1905 N. 45th St., in the larger space formerly occupied by Not A Number. Chroma will be an Aveda Salon focusing on hair and featuring a wide assortment of Aveda retail products. Owners Dan Deaver and Bryce Francis have been Wallingford residents for five years, and in an email to me, Dan told me that they’re excited to be located in Wallingford and are shooting for the week of June 25 to open, depending on completion of construction.
