Physical examination of a patient’s hair shows brittle, fragile, sparse and short hairs, the end product of hairs becoming exposed to the environment. Most patients also have sparse eyebrows and eyelashes (Fig. 1). [hairscientists.org]

It can't be cured, but treatments can relieve the scaling and make you feel more comfortable in your own skin. Ichthyosis is not one disease, but a family of about 20 skin conditions that lead to dry skin. [webmd.com]

Skin symptoms of dry skin (ichthyosis) are treated by applying skin softening emollients and products containing alpha-hydroxy acids which help break down skin buildup (keratolytics).This can be particularly effective after bathing while the skin is still [rarediseases.org]

Prognosis

Neoplastic risk this familial disease IS NOT a cancer prone disease but it involves the same complementation groups as in xeroderma pigmentosum and Cockayne syndrome (XPD, XPB), and share defects in similar genes Prognosis depends on the DNA repair defect [atlasgeneticsoncology.org]
The overall prognosis is generally favourable except for cosmetic facial problems and handicap from eye and ear anomalies. Intelligence is usually not affected. There is a ~3% for a future pregnancy 6. [radiopaedia.org]
The prognosis is typically poor for children with severe disease and the median age of death is reported as 3 years. [dermnetnz.org]

Pathophysiology
Pathophysiology Pollitt Syndrome is likely caused by a mutation in the TTDN1/C7orf11 (trichothiodystrophy nonphotosensitive) gene. [accesspediatrics.mhmedical.com]
Pathophysiology The genes XPB, XPD, and TTDA are involved in nucleotide excision repair and basal transcription as part of the basal transcription factor IIH (TFIIH). [dermatologyadvisor.com]
