Pili torti is a hair shaft disorder characterized by hair that does not grow long and is easily broken; the hair often has a coarse or spangled appearance. A diagnosis is made by light microscopy of flattened hair twisted 1800 along its axis. Although pili torti may be isolated, it is commonly associated with other congenital defects and therefore, if identified, further evaluation for possible neurologic deficits and ectodermal disorders is an important part of the clinical evaluation…

Presentation of monozygotic twins with identical hair structure disturbances typical for pili torti and multiple facial milia and review of syndromes and diseases with pili Torti and/or milia, with particular reference to Bazex-Dupre-Christol syndrome are presented.
Prognosis and Management of Congenital Hair Shaft Disorders without Fragility—Part II
TLDR
This study used keywords in the search engines PubMed and Medline to identify all publications in English related to the prognosis and treatment options for hair shaft disorders and extracted data from 96 articles that met search criteria.
Prognosis and Management of Congenital Hair Shaft Disorders with Fragility—Part I
TLDR
The objective was to review the literature regarding the prognosis and treatment options of hair shaft disorders using keywords in the search engines PubMed and Medline to identify all publications in the English language related to the prog outlook and management ofhair shaft disorders.
Improvement in Hair Loss and Better Hair Quality with Vitamin Therapy in Monilethrix
TLDR
Improvement of hair shaft structure and reduced hair breakage is reported in case of Monilethrix with the use of vitamins, minerals, amino acids and it is suggested that nutritional correction can offer relief to patients with hair shaft disorders with the understanding that it will be a better hair care though not a cure.

TLDR
The cases now reported show twisting of the hair in association with various other abnormalities, and their condition differs in certain aspects from the classical picture of pili torti as recorded in the world's literature.
Ultrastructural Study of Acquired Pili Torti‐like Hair Defects Accompanying Pseudopelade
TLDR
It was clear that the grooves and ridges were produced by the deformed hair cuticle and cortex, whose shapes were modulated by the asymmetric inner root sheath, which most likely resulted from a dysfunctional dermal papilla, which was affected by fibrosis.
TWISTED HAIRS (PILI TORTI)
TLDR
The anomalies of development of the hair are characterized by hairs of irregular shape, which are more or less short and thin; in general, dry and brittle, and break at the slightest provocation out of the follicle or along the shaft.

Trichothiodystrophy: sulfur-deficient brittle hair as a marker for a neuroectodermal symptom complex.
TLDR
Two-dimensional electrophoresis on the two protein fractions of the abnormal hair confirmed that the abnormality is caused by decreased synthesis of high-sulfur matrix proteins, which may account for the various disease features in these persons.

GRACILE syndrome, a lethal metabolic disorder with iron overload, is caused by a point mutation in BCS1L.
TLDR
Interestingly, the British and Turkish patients had complex III deficiency, whereas in the Finnish patients with GRACILE syndrome complex III activity was within the normal range, implying that BCS1L has another cellular function that is uncharacterized but essential and is putatively involved in iron metabolism.
