Types and Treatment of Hair Loss in Men and Women

In this article, the author focuses on 4 common hair loss disorders that occur in both men and women. The author discusses research related to androgenetic alopecia, telogen effluvium, alopecia areata, and scarring alopecia and provides details on how to approach and manage these diseases according to patient gender. There are a range of tools and tests that can assist with the diagnostic process and help ensure that relevant and high standards of patient care are maintained. In some cases, no medical intervention is always a treatment option. However, appropriate medical treatments, although still relatively limited in some cases, are safe and have proven efficacy. Hair loss has immense emotional and psychological impact in both genders, and it is always important to consider this when planning hair loss management pathways.

Vitamin D in trichology: a comprehensive review of the role of vitamin D and its receptor in hair and scalp disorders

Vitamin D plays an important role in maintaining the homeostasis of various biological systems. Beside its well-known function in calcium and phosphate metabolism, it plays a major role in pathophysiology of skin and adnexa. Indeed, vitamin D, through its receptor (VDR), decreases keratinocyte proliferation, improves their differentiation and modulates both cutaneous innate (antimicrobial activity and antigen presentation) and adaptative immunity (T and B lymphocyte function). The maintenance of normal hair is dependant on the integrity of the dermis, epidermis and hair cycles. Beside its effect on epidermal differentiation, VDR plays a vital role in preserving the hair follicle integrity. While the relevance of VDR has been fully elucidated, the real value of vitamin D in the hair follicle cycle still remains uncertain. To date, results in literature remain contradicting and far from definitive; still, the role of vitamin D in the various forms of human alopecia is likely to be significant. The aim of this article is to review evidence about the role of vitamin D and its receptor in trichology, with a focus on scarring and non-scarring alopecia and in particular on the potential therapeutic use of Vitamin D for hair and scalp disorders.

Trichoscopy of Dark Scalp

Trichoscopy (dermoscopy of the hair and scalp) is a technique that improves diagnostic accuracy and follow-up with hair and scalp disorders. Although several studies of trichoscopy have been made in Caucasian and Asian populations, little has been published regarding trichoscopy findings in skin of color, despite the great prevalence of hair diseases in populations with this kind of skin. The aim of this review was to describe the trichoscopic features of normal scalp and of hair disorders in patients with dark skin phototypes. This will help dermatologists to distinguish between unique trichoscopic features of dark skin, and allow them to provide more accurate diagnoses and treatments for these patients.
