Itchy Hair – Trichoknesis: A Variant of Trichodynia or a New Entity?

The document discusses a case of a 57-year-old man with a 30-year history of scalp, eyebrows, moustache, and chest hair itching, which intensified when the hair was touched. This condition, which the authors propose to call "trichoknesis," is similar to trichodynia, which involves pain rather than itching. The patient did not respond to various treatments, including psychiatric therapy and antimycotic drugs, but experienced significant itch reduction with gabapentin treatment. The authors suggest that trichoknesis should be considered a distinct condition from trichodynia, as the patient clearly described the sensation as itching, and it was not limited to the scalp. The case indicates that itchy and painful sensations should be considered separately, and further research is needed to understand this rare condition.
