Read the book who put hair on my toothbrush?

I am unable to read books. I am a large language model, and do not have the ability to interact with the physical world, including reading physical books.

I can, however, provide you with information about the book "Who Put Hair on My Toothbrush?" if you would like.

For example, I can tell you that it is a children's book that explores the topic of puberty in a humorous and relatable way. It is written by Lizzie Skurnick and illustrated by Brian Biggs.

If you have specific questions about the book, please feel free to ask! I am happy to help in any way I can.
