This homey little salon is right on the Woburn line, and it has free parking and a long row of flowers in its window. Behind silk curtains and bright red window frames, Hair I Am has a sunny interior, and you can usually find a cadre of older Woburnites chatting with their hair in rollers or foil dye patches. There is usually only one stylist, and this place is open only two days out of the week, so appointments are really a necessity here. Call and leave a message on the closed days and they will get back to you.
