Is the chapter "Hairs" in The House on Mango Street coherent? If so, how? If not, why?

The chapter is coherent both internally and in the overall
narrative. The internal coherence of the chapter is given by the consistent focus on the
hairs of the different family members. In addition the sketch, the second of the book,
adds details on the narrator's family members that were introduced by the first
vignette. "Hairs" also introduces the theme of gender roles and the narrator's search
for a community of women (the book is dedicated "A las Mujeres, To the Women") in her
description of her mother's comforting and reassuring hair. In addition, the narrator's
own hair which "never obeys barrettes or bands" symbolyzes her own yearning for freedom
and independence.
