Abstract
BACKGROUND: Numerous studies in recent decades have associated male androgenetic alopecia (AGA or pattern hair loss ) with the risk of cardiovascular disease. However, only 3 studies have addressed this association in female patients. Most studies considered the risk of myocardial infarction or mortality as a result of heart disease, without analyzing cardiovascular risk factors. OBJECTIVES: The objectives of this study were to analyze the presence of cardiovascular risk factors included in the Adult Treatment Panel-III criteria for metabolic syndrome, the prevalence of carotid atheromatosis, hormonal (aldosterone, insulin, testosterone, and sex hormone-binding globulin) factors, and acute phase reactant (C-reactive protein, fibrinogen, D-dimers, erythrocyte sedimentation rate) variables in male and female patients with AGA and in a control group, and to analyze differences among the groups. METHODS: This case-control study included 154 participants, 77 with early-onset AGA (40 male and 37 female) and 77 healthy control subjects (40 male and 37 female) from the dermatology department at a university hospital in Granada, Spain. RESULTS: Metabolic syndrome was diagnosed in 60% of male patients with AGA (odds ratio [OR] = 10.5, 95% confidence interval [CI] 3.3-32.5), 48.6% of female patients with AGA (OR = 10.73, 95% CI 2.7-41.2), 12.5% of male control subjects, and 8.1% of female control subjects. Atheromatous plaques were observed in 32.5% of male patients with AGA (OR = 5.93, 95% CI 1.5-22.9) versus 7.5% of male control subjects (P = .005) and 27% of female patients with AGA (OR = 4.19, 95% CI 1.05-16.7) versus 8.1% of female control subjects (P = .032). Aldosterone and insulin levels were significantly higher in the male and female patients with AGA versus their respective control subjects. Mean values of fibrinogen were significantly higher in male patients with AGA, whereas values of fibrogen, C-reactive protein, and D-dimers were significantly higher in female patients with AGA versus their respective control subjects. LIMITATIONS: The study of a wider sample of patients with AGA would confirm these findings and allow a detailed analysis of the above factors as a function of the degree of alopecia or between menopausal and premenopausal women. CONCLUSION: The determination of metabolic syndrome and ultrasound study of the carotid arteries may be useful screening methods to detect risk of developing cardiovascular disease in male and female patients with early-onset hair loss and signal a potential opportunity for early preventive treatment.

Alopecia: botanical approaches in review.
Abdullah F, Rashid RM.

Abstract
The use of herbal medications in dermatologic disease has become common practice among consumers. In this paper, the authors review and discuss the existing evidence-based botanical modalities in the peer-reviewed literature with a particular focus on various presentations of hair loss. To maximize potential clinical application, this review has been limited to human studies. The goal of the study was to provide a thorough evaluation of the current understanding of the use of non-pharmaceutical botanical products in the treatment of hair loss.

Does D matter? The role of vitamin D in hair disorders and hair follicle cycling.
Amor KT, Rashid RM, Mirmirani P.

exerpt..

"...Limited studies have been done in humans to elaborate the role of vitamin D in the hair cycle. A potential application for vitamin D is in chemotherapy-induced hair loss. Topical calcitriol has been shown to protect against chemotherapy-induced alopecia caused by paclitaxel and cyclophosphamide. However, topical calcitriol failed to protect against chemotherapy-induced hair loss caused by a combination of 5-fluorouracil, doxorubicin, and cyclophosphamide and a combination of cyclophosphamide, methotrexate, and 5-fluorouracil [36, 37]. The ability of topical calcitriol to prevent chemotherapy-induced alopecia may therefore depend on the chemotherapy agents used. Of note, the studies in which no effects were observed, were small and may have used doses of vitamin D that were inadequate to protect against chemotherapy-induced hair loss. The more potent vitamin D3 analogs used on mice by Vegesna et al. have yet to be evaluated in humans.

Another potential application for vitamin D is in hair loss due to scalp psoriasis, which is associated with an increased telogen to anagen ratio. Although vitamin D3 analogs have been used in combination or as an alternative to topical steroids to treat scalp psoriasis for many years, their ability to combat the associated hair loss has not been thoroughly evaluated. A placebo-controlled trial with 26 patients showed that calcipotriol did not affect the telogen to anagen ratio after 6 weeks of treatment, but the optimal effect of calcipotriol on scalp psoriasis is not seen until 8 weeks. Thus, the follow up may have been too brief to detect an effect of calcipotriol on hair loss.

It has been suggested that an optimal concentration of vitamin D is necessary to delay the aging phenomena, including hair loss. A cross sectional study of 296 healthy men was done to determine the association, if any, between male pattern baldness and serum 25-hydroxyvitamin D levels. Based on this study, the extent and severity of male pattern baldness does not appear to be associated with serum 25-hydroxyvitamin D levels . Additional studies in subjects with age-related or senescent hair thinning as well as in women with female pattern hair loss could be considered to see if there is an association of hair loss with serum 25-hydroxyvitamin D levels.

Because it is known that the absence of VDR leads to hair loss, it was hypothesized that there may be VDR gene polymorphisms (Bsml, Apal, and Taql) in patients with alopecia areata. A study of VDR genotypes in 32 patients with alopecia areata and 27 controls showed no association between these VDR gene polymorphisms and alopecia areata. A separate study also showed that there was no relationship between the VDR gene FokI polymorphism and alopecia areata......
