Abstract
Loose anagen syndrome (LAS) and short anagen syndrome (SAS) are congenital hair disorders presenting with reduced hair length with or without hair thinning. We conducted a non-validated online questionnaire of self-identified familial participants in a Facebook support group to assess psychologic symptoms, including anxiety, depression, low self-esteem, sadness, insecurity, worry, frustration, and body dysmorphia, in patients and their caregivers. Of 163 total respondents, negative psychologic symptoms were reported in 44.2% (38/89) of LAS patients, 48.3% (43/89) of LAS caregivers, 56.8% (42/74) of SAS patients, and 47.2% (35/74) of SAS caregivers. Our data indicate that both LAS and SAS have strong psychologic, emotional, and social impacts on affected children and their caregivers.
