Cutis. 2017 July;100(1):E12-E14 Practice Points Hereditary hypotrichosis simplex (HHS) is a rare form of hypotrichosis that typically presents in school-aged children as worsening hair loss localized to the scalp. [mdedge.com]
Structural hair defects may be presented with a genetic disorder affecting hair growth or part of a congenital syndrome or may indicate underlying metabolic disorders, or may be associated with other diseases. [e-ijd.org]
The mutations in the LIPH gene, identified in the present study, include a novel homozygous splice acceptor site mutation (IVS4-1G C). [medicaljournals.se]

Alopecia
Therefore, our patient’s family was referred to the National Alopecia Areata Foundation website () for resources on discussing alopecia with school-aged children. [mdedge.com]
Heritability: Autosomal recessive inheritance AKA: hypotrichosis caused by mutation in LIPH, woolly hair, autosomal recessive 2, with or without hypotrichosis, hypotrichosis 7, Mari type alopecia universalis congenita, HYPT7, total hypotrichosis, Mari [monarchinitiative.org]
In addition, and as in alopecia areata, we offer an immunological theory as an explanation because of the presence of the lymphocytic infiltrate, especially around hair follicles. [azmj.eg.net]
Mild cases have hair loss limited to the scalp, while severe cases show generalized alopecia. Hair shaft abnormalities are characteristic, demonstrating regularly-spaced, spindle-shaped swellings. [medicaljournals.se]

Sparse to No Eyebrows
The scalp hair is sparse to absent, eyebrows and eyelashes are normal or short and sparse, and the body hairs are normal or sparse. [nature.com]
Affected individuals have sparse hair on the scalp, sparse-to-absent eyebrows and eyelashes, and sparse body hair. Affected male individuals have normal beard hair (1–3). [medicaljournals.se]
Eyebrow loss and presence of wiry, twisted hair is important for diagnosis. [6] Other ectodermal structures are normal. Diffuse follicular hyperkeratosis with milia-like facial lesions may be present. [ijtrichology.com]

Lymphocytic Infiltrate
Within the dermis, there is perivascular and patchy predominantly lymphocytic infiltrate. Some lymphocytic infiltrate is also noted about the hair follicles (hematoxylin–eosin stain, original magnification, 100 and 400, respectively). [azmj.eg.net]
Treatment
Both bimatoprost treatment cohorts displayed significant improvements compared with the vehicle cohort after 1 month, which continued during the treatment and post-treatment periods ( P .035, all comparisons). [healio.com]

Management and treatment There is no treatment for hypotrichosis simplex available to date. The documents contained in this web site are presented for information purposes only. [orpha.net]

The prognosis of this disorder is extremely poor, as patients die in infancy. Most deaths are due to recurrent infection, acidosis and critical bleeding [ 2 ]. [casereports.in]
Etiology
Hypotrichosis with keratosis pilaris is a very rare inborn skin disorder of unknown etiology. Here we report a rare case of hypotrichosis with keratosis pilaris in a 7-year-old boy. [azmj.eg.net]
Etiology Both autosomal dominant and recessive modes of transmission have been reported for HHS.Autosomal dominant HHS affecting both scalp and body hair has been reported in one Italian and two Pakistani families as due to mutations in the APCDD1 gene [orpha.net]
No clinically meaningful differences in AE rates by etiology of eyelash hypotrichosis were noted. [dovepress.com]
The etiology suggests that there could be poor absorption of other nutrients as well. [omicsonline.org]
Incidence of AEs by etiology. The overall incidence of AEs, regardless of causality, was slightly higher for subjects receiving up to 12 months of bimatoprost 0.03% compared with up to six months of vehicle (47.4% vs 34.3%, respectively; Table 3 ). [jcadonline.com]

Prevention
Submit Tips While some causes of hair loss can be treated or prevented, this is not always possible. [wikihow.com]
Folliculitis following pubic hair transplantation In order to prevent movement of transplanted hair, I used a spray adhesive (3M) on the transplant sites (Figure 2). [idnps.com]
At fault is a genetic defect that prevents certain receptors on the surface of hair follicle cells from being correctly formed. [belgraviacentre.com]
Subjects with systemic diseases, including all types of alopecia areata, which could prevent hair growth or produce abnormal growth were excluded, along with subjects with substantial permanent eyebrow loss due to overgrooming; any skin pigmentation/depigmentation [journals.lww.com]
