Harriet

Harriet is a pink poodle who runs Shampoodle, a barber shop. Harriet wears a blue, red, and white striped apron resembling the French flag (possibly because the poodle is the national dog of France). It can also represent an old fashioned barber pole, which features the same blue, red, and white stripes. She changes the hairstyle of the player depending on their answers to a series of questions. It usually costs 3,000 Bells to use Harriet's services. She first appears in, working in a store in Nookington's, and again appears in and , with her own stores in the city and Main Street respectively. Her name is a pun on the word "hair," and her Japanese name is a pun on "cut," both in reference to her profession.

In, Harriet is the proprietor of Shampoodle, which is located within Nookington's. She will offer the player a haircut, which is styled based on the answers of a series of questions - the answers usually relate to a stereotypical hairstyle by a type of group or genre. The player can only get one haircut per day. Harriet will be at the Roost Café, 11:00PM – 12:00AM, Mon - Fri, but the player must have Nookington's in their town first.

After the player has had all the different hairstyles, Harriet will offer them a haircut of the opposite gender.

Attempting to leave the salon after paying, but before receiving a haircut, will prompt a dialogue from Harriet. She will not let the player leave without making use of her services, unlike in.

In, she has her own beauty salon in the city and no longer works in Nookington's. The store remains under the same name of Shampoodle and her character traits are very much unchanged, but she now offers a wider variety of hairstyles. Additionally, Harriet now offers a Mii mask, a mask that is styled on a Mii character created on the Wii. The style costs 3,000 Bells as well (except for the first Mii Mask, which is free), but only one style can be stored. She will only style the player's hair once per day.

In, Harriet runs Shampoodle again, which is situated above the Able Sisters store on Main Street. In order to unlock the salon, the player must spend 10,000 Bells at Able Sisters or Kicks. Ten days must also have passed since Kicks was built. She offers the player the option of changing their eye color with contacts. Her personality and services remain unchanged, except for that new feature.

Harriet appears in if the player has purchased the Harriet's Salon Station special furniture and has placed it in their campsite or cabin. The special furniture costs s and was available from May 16, 2020 to July 15, 2020.
