Medusa in this work is a very young child living in the modern world. The book opens with her looking crossly at a hairbrush. The reader follows Medusa's father's vain attempts to brush her hair. She prevaricates, jumping on the bed, doing somersaults, and brushing her toy mermaid's hair. Grandma arrives and is shocked to see Medusa's wild locks. Grandma takes Medusa on a trip. As far as Medusa is concerned, the trip is to get sweets. Medusa is taken to a hairdresser, who finally manages to tame her hair, and Medusa is satisfied when she gets a lollypop. The story closes with Medusa's father beginning an attempt to brush Medusa's teeth. A one-page summary of the traditional ancient myth closes the book. The summary is written in a slightly different register, written for the adult reader and/or children at the outer edge of the age bracket that the book is aimed at (i.e. c. 4–8).

This is a beautifully illustrated series that creatively transposes ancient myths into real-life scenarios faced by pre-school-aged children. Subtle ancient-style features are included in the design of each volume in the series: a brightly-coloured Greek key runs vertically along the cover beside the spine; the series name is written on a scroll, with the "S" of "myths" written in a jagged, inscription-like style; on the spine, the main character is shown standing upon a Doric column, with the name of the book written on the column. The image of the character atop a column is repeated in the interior title-page. A theme, or moral lesson, is included in each volume in the fore-notes in the style of a dedication. In Brush Your Hair, Medusa!, the dedication is To finding your style. This plays out in the book through the theme of Medusa's strong preferences, mixed with the need for her to conform to at least some extent. 

Aspects of the myth of Medusa are carefully introduced into the visual landscape. Ancient Medusa is infamous for her head of snake hair; here Medusa has wild hair and plays with a snake toy. Mini Myths Medusa also has a mermaid toy, and the mermaid figure has a pronounced history of association with ancient myth through its frequent conflation with the Sirens. When Grandma comes to collect Medusa, a close-up shows her shocked – petrified – by Medusa's wild hair, a detail which reflects the tradition that a look from Medusa turns mortals to stone. Typically in this myth, Perseus defeats Medusa with the help of Hermes, which includes the gift of winged boots. Here the male hairdresser wears a cap which has a pair of ancient style wings on each side, echoing aspects of both Perseus and Hermes.

This title is unusual in the series for being the only one in which the child character is created from a monster rather than a human protagonist. This creates the potential challenge of the need to "defeat" the monster/child. This challenge is well-handled by the decision to focus on the adults tackling Medusa's essentially tame bad behavior and extreme hair, rather than more explicitly challenging or changing Medusa herself. Cutting the hair replaces cutting the head off, but Medusa does not actually feel chastened by the experience of going to the hairdressers, in fact she is pleased to have a lollipop. Her "wildness" is tamed without her spirit being crushed. This is well-handled in the sense that the book's primary aim is to help children face challenges in their young lives, and children who dislike having their hair combed or cut are likely to be encouraged by Medusa's positive response, where representation of more drastic action would be off-putting and therefore counter-productive.

The summary of the myth that comes at the end is also careful about the depiction of the dynamics within the myth. It refers to Hermes and Athena helping Perseus by providing a sickle as sharp as scissors and a mirrored shield, and nymphs providing "winged sandals" (for ancient traditions on this see e.g. Hesiod, Shield of Heracles, lines 216–236; Euripides, Electra, line 460; Apollodorus, Library, 2. 36–42; Pausanias, Guide to Greece 3. 17. 3, and numerous vase depictions). Medusa is simply said to have been "defeated," avoiding reference to her death or decapitation – details perhaps regarded as too violent for a section still available to children, even if this section appears to be aimed at slightly older children.

This series introduces very young children to some of the names and images associated with antiquity, preparing them for encountering these images and characters again in different contexts. At a very fundamental level, these books act on and communicate the idea that ancient mythology contains concepts that can help in children's development – social and emotional. The families in the books come from a range of ethnicities, with the implication that classical myths can be for anyone, regardless of their ethnic background. Children at the outer edge of the age bracket for these books can also enjoy the summary that comes at the end of the book, which creates the opportunity for an early encounter with the sophisticated concept of characters reappearing in different contexts and stories, and stories working on different levels – things which are likely to stimulate thought and a nuanced approach to stories and story-telling.
