Introduction:Currently there are only a limited number of drugs available for treatment of androgenetic alopecia and telogen effluvium. However, certain plants and their standardized extracts may provide some clinical benefits against hair loss. We formulated a herbal shampoo and a solution to evaluate their efficacy, safety, and synergy in hair loss. Methods: We conducted a randomized, placebo-controlled, single-blind, clinical and instrumental study for 6 months on 120 subjects with androgenetic alopecia and telogen effluvium, confirmed by pull test and phototricogram. Each subject was examined monthly. At the end of the study, a self-assessment test was carried out. Results: Herbal formulations were found to be more effective in preventing and reducing hair loss than placebo at every assessment point. Anagen/telogen ratios improved significantly in the study group. In addition, concomitant use of the shampoo and solution were found to be more effective than single product use. Conclusion: We interpret this eutrophic effect for scalp hair as the final outcome of the entire content of our herbal formula, which has antiandrogenic, anti-inflammatory, antioxidative, angiogenic, and hair-stimulating features. In combination, these features help prevent hair from falling out and reducing hair loss.

Summary Background Acne vulgaris is a common skin disease characterized by increased sebum production, inflammation, and colonization of Propionibacterium acnes (P. acnes) on pilosebaceous follicles. Aims To determine the efficacy of two different plant extracts against P. acnes and to analyze the gene expression levels of IL‐1α, SRD5A1, and TNFα in HaCaT cells treated with these plant extracts. Methods Anti‐acne extract 1 (AE1) consisted of Juglans regia (walnut husk), Myrtus communis (myrtle leaves), Matricaria chamomilla (chamomilla flowers), Urtica dioica (stinging nettle leaves), and Rosa damascena (rose flowers). Anti‐acne extract 2 (AE2) contained Brassica oleracea var. botrytis (broccoli) and B. oleracea var. italica (cauliflower). The antimicrobial activities of the extracts were tested on two different P. acnes strains: the reference strain of P. acnes (ATCC 51277) and the clinical isolate from a patient. The minimum inhibitory concentration (MIC) of the extracts was determined using the broth dilution method. Human keratinocyte cells were used for in vitro tests. Gene expression analyses were performed with RT‐qPCR. Results The MIC values of the extracts were below 1/2048 µg/mL. In the gene expression analysis, AE1 increased the expression level of TNFα (1.1719, P < 0.0001), suppressed the expression level of IL‐1α, SRD5A1 (0.0588, P = 0.0231; 0.3081, P = 0.0351), respectively. AE2 suppressed gene expression level of IL‐1α, SRD5A1, TNFα (0.3815, P = 0.0254; 0.3418, P = 0.0271; 0.1997, P = 0.0623). Conclusions Both herbal extracts demonstrated strong antibacterial and anti‐inflammatory activity in this preliminary trial. In conclusion, the topical application of these botanical extracts can be good candidates for local acne treatment.

We aimed to test the anti-inflammatory and angiogenic properties of two different thermal waters at the cellular level in human keratinocyte cells in the present study. Two different thermal waters, thermo-mineral BJ1 (Bursa, Turkey) and oligomineral BG (Bolu, Turkey), were tested in human keratinocyte (HaCaT) cell line. HaCaT cells were incubated for 3 days with thermal waters; RNA isolation was carried out in the treated and untreated cells. The gene expressions of TNFα, IL-1α, and VEGF were measured using the RT-qPCR. The tested thermal waters significantly decreased the expression of IL-1α (BJ1 93% p = 0.0024 and BG 38% p = 0.0303). BJ1 and BG thermal waters downregulated the expression of TNFα (59% p = 0.0001 and 23% p = 0.0238 respectively). Furthermore, BJ1 and BG significantly downregulated the gene expression of VEGF (98% p = 0.0430 and 15% p = 0.0120). The observed decrease in the gene expression of TNFα and IL1α could be interpreted as an anti-inflammatory effect of mineral waters on HaCaT cells. Moreover, the suppressed VEGF expression might be an indicator of the antiangiogenic effect on human keratinocytes. Therefore, we hypothesized that depending on their specific chemical composition such as silica (128 mg/L) in BJ1 and hydrogen sulfide (1.2 mg/L) in BG, thermal waters suppress pro-inflammatory cytokines and angiogenic growth factor. These preliminary findings might give insight on the underlying mechanisms of the therapeutic benefits observed in some skin diseases such as rosacea and psoriasis.

Topical Fc leaf extract may be beneficial for some inflammatory disorders and androgen-dependent disorders of the skin such as androgenetic alopecia.

Vitiligo is a pigment disease characterized by the disruption of melanocyte structure and function. Its etiology is unknown; however, genetic predisposition, biochemical factors, and neural mechanisms are thought to be effective. Although many agents are being used for its treatment, generally there is no absolute cure. The aim of the present study is to evaluate the effectiveness of topical Nigella sativa seed oil on vitiligo patients. Thirty‐three vitiligo patients were included in the study. Totally 47 areas were evaluated in all patients. Cream containing N sativa seed oil was topically applied to hands, face, and genital region two times a day for 6 months. Statistically significant repigmentation was detected in hands, face, and genital region, the three treatment areas, and the p values are found .005, .001, and .004, respectively. N sativa can be used as an adjuvant therapy that can contribute to the treatment especially in sensitive skin areas like genital region.
