This artwork is a striking example of Picasso's cubist style, which he developed alongside Georges Braque in the early 20th century. In this painting, Picasso explores the artist's theme and model, a subject that has fascinated him throughout his career. The composition features fragmented forms and geometric shapes, characteristic of cubism, where objects are depicted from multiple viewpoints simultaneously. The figure of the painter and the model are intertwined, their forms merging and overlapping.

The title of the painting refers to the bow in the model's hair, a detail that adds a touch of whimsy and femininity to the composition. Picasso often incorporated elements of everyday life into his artworks, infusing them with personal and symbolic meaning.

Overall, Peintre et Modèle avec un Noeud dans Les Cheveux exemplifies Picasso's innovative approach to art, pushing the boundaries of representation and perception.
