**What is Netherton Syndrome a.k.a.**Bamboo Hair Syndrome ?
In trichorrhexis invaginata (TI), a.k.a. Bamboo hair, the hair shaft invaginates atseveral point along its length.
Low magnification trichoscopy shows multiple small nodules spaced at irregular intervals.
TI is a pathognomonic finding of Netherton syndrome, a quaint autosomal recessive condition caused by mutations in the SPINK5 gene.
Hair improves with aging, but the eyebrows usually exhibit some hairs with the abnormality and should be checked for diagnosis.
Trichoscopy allows fast diagnosis of this condition as the affected hairs might be difficult to detect, as only 2050% of hair is affected.
Treatment aims to deal with the skin findings of Netherton syndrome more than the hair abnormality.
It is strived in this Booklet to precisely describe the Cause, Clinical presentation, Diagnostic approach, Trichoscopy, Histological findings, Management etc., along with plenty of Images for better understanding.
