Although the major white adipose depots evolved primarily to store energy, secrete hormones and thermo-insulate the body, multiple secondary depots developed additional specialized and unconventional functions. Unlike any other fat tissue, dermal white adipose tissue (dWAT) evolved a large repertoire of novel features that are central to skin physiology, which we discuss in this Review. dWAT exists in close proximity to hair follicles, the principal appendages of the skin that periodically grow new hairs. Responding to multiple hair-derived signals, dWAT becomes closely connected to cycling hair follicles and periodically cycles itself...

Hair growth occurs periodically in a cycle that consists of three different phases: growth, regression, and resting. The length of each phase is regulated by both intrinsic and extrinsic factors throughout life, and influenced by physiological and pathological conditions. Elongation of the resting phase and shortening of the growth phase occur during physiological ageing and in baldness, respectively. In vivo discrimination of each phase of the hair cycle can be used to research for regeneration of hair follicles as well as to evaluate the efficacy of hair regrowth treatments in the same individual...

Diphenylcyclopropenone (DPCP) is an effective topical immunotherapy for recalcitrant alopecia areata (AA), which sometimes requires prolonged treatment. We developed a new treatment protocol to shorten the duration of therapy. This study aimed to compare the efficacy and safety of the new treatment protocol with the standard treatment protocol in the treatment of recalcitrant AA. We conducted a 6-year retrospective comparative study of patients with AA who received one of the DPCP treatment protocols at our institute...

There are many laser technologies that are being tested that claim to support hair regrowth for patients with alopecia areata (AA). In this paper, we will determine whether the body of evidence supports the use of devices using monochromatic light sources to treat AA. Articles were gathered from PubMed, Embase, and the Cochrane database using these keywords: lasers, excimer laser, low-level laser therapy (LLLT), low-level light therapy, alopecia, alopecia areata, and hair loss with a category modifier of English...

Background: Simvastatin belongs to the statin family, whose members have immunomodulatory activities. Ezetimibe have synergetic effects when co-administered with simvastatin. In several case reports, alopecia totalis and alopecia universalis were successfully treated with simvastatin/ezetimibe, suggesting that this combination could be a new efficient therapy for recalcitrant alopecia areata (AA). Objective: To verify the efficacy of the simvastatin/ezetimibe combination therapy for recalcitrant AA and investigate the relationship between various treatment responses and prognostic factors...

BACKGROUND: Houttuynia cordata Thunb (HC) is a traditional herbal medicine widely used in Asia for the treatment of patients with alopecia, usually in combination with other two herbal medicines (Perilla frutescens var. acuta (PFVA) and green tea (GT)). However, the effect of this herbal complex has not been clearly demonstrated. We sought to determine the hair growth-promoting effect of this herbal complex (HC, PFVA, and GT) in the animal model. METHODS: Six-week-old male C57BL/6 mice were randomly divided into four groups (negative control, finasteride (1 mg/kg) as a positive control, and two (200 and 400 mg/kg) concentrations of the herbal complex as experimental groups) and were fed its corresponding medications orally for 25 days...

BACKGROUND: Contact immunotherapy with diphenylcyclopropenone (DPCP) is presently considered the treatment of choice for extensive alopecia areata (AA). However, a major concern with contact immunotherapy is that it causes various adverse effects (AEs) that contribute to discontinuation of treatment. OBJECTIVE: We investigated whether a modified DPCP treatment protocol can promote hair regrowth with fewer AEs. METHODS: All patients were sensitized with 0...

Lupus alopecia is usually difficult to treat. We report a case of a 40-year-old woman with Sjögren's syndrome and atopic dermatitis who presented with discoid lupus erythematosus on the forearms and lupus erythematosus profundus with alopecia involving the scalp. A biopsy specimen taken from the discoid lupus erythematosus lesion on the forearm further exhibited a xanthomatous reaction, which however was not detected in another specimen from the lupus erythematosus profundus on the scalp. Treatment with oral hydroxychloroquine showed dramatic effects and complete hair regrowth was obtained 3 months later...

Alopecia areata (AA) is an autoimmune inflammatory disorder of hair, characterized by non-scarring hair loss. 308-nm Excimer lamp (EL) has been reported as one effective modality in the treatment of AA. Khellin is a furanochromone photosensitizer whose chemical structure is close to psoralens and has previously proven its efficacy in vitiligo in association with UVA. We evaluated the efficacy and safety of a combination of topical khellin and 308-nm EL in the treatment of a refractory ophiasic AA (OAA), of 1-year evolution, in a 5-year-old boy...

The transformation of fibrotic healing process to regenerative one has great potential to fully restore wounded skin. The M2 macrophage phenotype promotes constructive tissue remodeling and instructs tissue repair in a regenerative manner. It is hypothesized that hydrogels that can establish robustness of endogenous cells to regulate M2 phenotype will promote constructive dermal remodeling. Toward this end, a series of dextran-based bioabsorbable hydrogels are developed and self-crosslinkable dextran-isocyanatoethyl methacrylate-ethylamine (DexIEME) is identified as the potential scaffold...

Clostridium difficile infections can be life-threatening but are increasingly being treated successfully with fecal microbiota transplantation (FMT). We report two patients with alopecia universalis who developed subsequent hair regrowth after FMT for treatment of recurrent C. difficile infections. Gut microbiota may have immunomodulatory effects in autoimmune conditions such as alopecia areata, and further study may elucidate disease mechanisms and lead to alternative treatment options for these patients for whom treatment options are currently limited...

This study investigated the potential hair regrowth effects associated with a plant extract of Perilla frutescens, which was selected due to its putative hair regrowth activity. Extracts were prepared from dried P. frutescens suspended in distilled water, where the resultant aqueous suspension was fractionated sequentially using hexane, ethyl acetate, n-butanol, and distilled water. We observed that the n-butanol fraction resulted in the highest hair regrowth activity. The n-butanol soluble fraction of P. frutescens extract (BFPE) was further separated using AB-8 macroporous resin and silica gel chromatography to obtain rosmarinic acid (RA), which demonstrated effective hair growth regeneration potential...

BACKGROUND/AIMS: Alopecia areata is a common immune-mediated hair condition with limited treatment options and success rates. There is evidence that statins, which are used for reducing atherogenesis and cardiovascular disease, have immunomodulatory activities and therefore may also be used for treatment of selected dermatologic conditions, including alopecia areata. Among treatments evaluated for alopecia areata, oral simvastatin/ezetimibe therapy is currently under the scrutiny of expert opinion...

Hair loss stemming from different types of alopecia, such as androgenic alopecia and alopecia areata, negatively affects over half the population and, in many circumstances, causes serious psychosocial distress. Current treatment options for alopecia, such as minoxidil, anthralin, and intralesional corticosteroids, vary efficacy and side effect profiles. It is known that low-level laser/light therapies (LLLT), or photobiomodulations, such as the US FDA-cleared HairMax Lasercomb®, He-Ne laser, and excimer laser, are relatively affordable, user-friendly, safe, and effective forms of treatment for hair loss...
