curcumin and Alopecia

Alopecia areata is a common non-scarring alopecia, mainly manifested as sudden localized patchy alopecia. It is currently believed to be related to autoimmune, genetic, emotional stress, and endocrine factors.. The aim of this study was to evaluate the efficacy and safety of the mixed preparation of piperine, capsaicin, and curcumin on alopecia areata treatment.. Sixty patients were enrolled in this study and divided into 2 groups randomly: topical treated with the mixed preparation (case) twice daily and 5%minoxidil (control) once daily for 3 months. The degree of hair loss was assessed by SALT and dermoscopy.. On the completion of the study, compared with baseline, statistically significant regrowth occurred in both groups (p < 0.05). The mean SALT scores and hair follicle status under trichoscopy at baseline and at the end of 12 weeks in the mixed preparation group and in the minoxidil group were comparable, respectively. The effective rate of mixed preparation group was 63.33% and minoxidil group was 70%. Adverse symptoms were temporary and no serious adverse event occurred.. Based on our findings, the mixed preparation of piperine, capsaicin, and curcumin is effective in treating alopecia areata, but it has not been shown to be superior to minoxidil in short-term therapy.

Sesquiterpenes in Curcuma aeruginosa Roxb. inhibit steroid 5α-reductase and dihydrotestosterone production, and reverse androgenic alopecia. This study sought to show that a high sesquiterpene C. aeruginosa extract (CA-ext) retards axillary hair growth in women.. Thirty women (age 20-52 years) were recruited into a 12-week, double-blind, placebo-controlled intervention for CA-ext treatment, where they were randomly allocated to a left or right armpit group. At weekly intervals, axillary hair length was measured videometrically, the hair was shaved, and lotion was applied (to the contralateral axilla) twice daily via roll-on applicators containing either CA-ext or placebo. The primary endpoint of the study was hair growth.. Participants showed 22% (range 8-56%, p < 0.0001) reduced axillary hair growth with CA-ext compared to placebo, albeit delayed by 6 weeks. Participants were satisfied with the treatment and no apparent adverse effects were reported. The quantities of lotion used for each axilla were identical between test and placebo throughout the trial for each participant. Participants reported having shorter and finer armpit hair with the test lotion but disliked its smell, even though it was perfumed. The "free of irritation" description gained the highest questionnaire ratings.. CA-ext in lotion is an efficacious inhibitor of axillary hair growth, the preparation was well accepted and matched the effectiveness of finasteride. Thus, with some refinement, it should provide an alternative pharmacological treatment for unwanted androgenic hair.

Several botanically derived agents are available for the treatment of male-pattern baldness.. The aim of this study was to evaluate the efficacy of 5% hexane extract of Curcuma aeruginosa, a botanically derived inhibitor of 5α-reductase and 5% minoxidil in the treatment of androgenetic alopecia.. Eighty-seven men with androgenetic alopecia (AGA) were randomized to receive 5% Curcuma aeruginosa, 5% minoxidil, combination formulation (5% hexane extract of Curcuma aeruginosa + 5% minoxidil) or placebo, twice daily for 6 months. Efficacy was assessed by target area hair count, global photographic review as well as patients' subjective assessments of hair regrowth and hair shedding.. There were statistically significant improvements in global photographic review (p < 0.001), subjects' overall assessments of hair regrowth (p = 0.008), and hair shedding (p = 0.004) when the combination formulation was compared with placebo. Similarly, treatment with 5% minoxidil and 5% C. aeruginosa extract also led to some degrees of hair regrowth. There were no serious adverse events during and after the study.. In men with hair loss in the vertex area of the scalp, the combination of 5% hexane extract of C. aeruginosa and 5% minoxidil slowed hair loss and increased hair growth.

Androgen-inducible transforming growth factor beta (TGF-beta1) derived from dermal papilla cells (DPCs) is a catagen inducer that mediates hair growth suppression in androgenetic alopecia (AGA). In this study, a cell-based assay system was developed to monitor TGF-beta1 promoter activity and then used to evaluate the effects of activated TGF-beta1 promoter in human epidermal keratinocytes (HaCaT). To accomplish this, a pMetLuc-TGF-beta1 promoter plasmid that expresses the luciferase reporter gene in response to TGF-beta1 promoter activity was constructed. Treatment of HaCaT with dihydrotestosterone, which is known to be a primary factor of AGA, resulted in a concentration-dependent increase in TGF-beta1 promoter activity. However, treatment of HaCaT with the TGF-beta1 inhibitor, curcumin, resulted in a concentration-dependant decrease in TGF-beta1 expression. Subsequent use of this assay system to screen TGF-beta1 revealed that HaCaT that were treated with apigenin showed decreased levels of TGF-beta1 expression. In addition, treatment with apigenin also significantly increased the proliferation of both SV40T-DPCs (human DPCs) and HaCaT cells. Furthermore, apigenin stimulated the elongation of hair follicles in a rat vibrissa hair follicle organ culture. Taken together, these findings suggest that apigenin, which is known to have antioxidant, anti-inflammatory, and anti-tumor properties, stimulates hair growth through downregulation of the TGF-beta1 gene. In addition, these results suggest that this assay system could be used to quantitatively measure TGF-beta1 promoter activity in HaCaT, thereby facilitating the screening of agents promoting hair growth.
