They’re “best friends,” they say. “Inseparable.”

Daughter-and-mother team Kelly Iacobucci and Audrey Iacobucci have written mystery novels together. They regularly vacation together. And now they’ve opened a hair salon together.

A Hair Event, located at 1857 Western Ave., belongs to Kelly Iacobucci, but Audrey Iacobucci, a retired registered nurse, will be helping out.

And they’re not the only family members involved. Both of their husbands work in construction, said Audrey Iacobucci. Kelly’s father, Joseph Iacobucci, is retired from the state’s Department of Transportation, so he improved the drainage and added a parking lot, Audrey said, while both he and Todd Smith, Kelly’s husband, worked together to overhaul and transform into a business the single-family home that had stood unoccupied for about two years.

The property had already been zoned business non-retail professional, said Acting Chief Building and Zoning Inspector Jacqueline Coons.

The two women have seen several dear relatives and friends — Audrey Iacobucci’s mother-in-law, the sister of a friend, and a customer who had become a very close friend — die of breast cancer, and they began to want to do something to help.

They were aware that chemotherapy causes hair loss and that women undergoing treatment can feel self-conscious about their appearance.

In a spacious private room, Kelly Iacobucci will do hair, while Audrey will do wig fittings by appointment for customers and also help keep things tidy.

A percentage of the profit from every wig sale will go to breast-cancer research, said Kelly Iacobucci.

Next, Joseph Iacobucci will install wall shelving in that room. The women hope to find an antique buffet to use there as a table, to give it “a homey feel.”

The two women hope to have the wig-fitting service up and running by March 1.

The private room will be devoted to just one client at a time, whether for a hair or a wig appointment.

The business will not be able to accept health insurance for wigs right away, “but when we get it up and running, we will,” said Audrey Iacobucci.

This is the first shop that Kelly Iacobucci has owned. She has been working as a hairdresser at area salons for 25 years and has her own clientele. She plans to rent out the four stylist’s booths in the main room.

After Kelly Iacobucci decided on the store’s name, A Hair Event, her mother came up with a slogan and had it printed on her business cards: “In the event you need hair, we’ve got you covered.”
