Arnold Zimmerman founded National Hair Centers in 1975 after working as a salesperson in the hair replacement industry in Washington D.C. When the family moved to the Valley, Arnold opened a location in Glendale, then moved to Maryland and 7th Street in 1979. The company relocated to its current location on 7th Street in 1990. Today it is the largest firm of its kind in the United States, with a staff of 35 employees who perform cosmetic wizardry for the folically challenged ranging from off-the-head hair replacement to surgical, permanent restoration.
