Studysummary This article reviews diagnostic approaches for noncicatricial alopecias and reports no new results; it highlights the importance of scalp biopsy in some cases for accurate diagnosis. Our plain-language summary of this paper — not a Tressless recommendation.
The document from 2014 discussed the diagnosis of noncicatricial alopecias, which are types of hair loss that do not result in scarring. The diagnosis is primarily based on the patient's clinical history and a thorough clinical examination. Additional diagnostic tools such as dermoscopy, trichoscopy, and trichogram can be useful. However, in some cases, a scalp biopsy may be necessary to confirm the diagnosis. The main types of noncicatricial alopecias mentioned in the document include androgenetic alopecia, alopecia areata, trichotillomania, traction and pressure alopecia, temporal triangular alopecia, ageing alopecia, loose anagen syndrome, telogen effluvium, and anagen effluvium.
