Androgenetic alopecia is a common type of hair loss, which is generally influenced by genetic factors and systemic androgens resulting in follicular miniaturization.1 It can cause cosmetic problems leading to psychological distress among affected men and women. Effective standard medical treatments available are topical minoxidil 2 to 5%, oral finasteride, oral dutasteride, and hair transplantation.

Objective: To identify the prevalence of female pattern hair loss (FPHL), hair characteristics, and associated factors in healthy postmenopausal women.

Methods: Two hundred postmenopausal women aged 50 to 65 years were recruited. Each participant was evaluated for FPHL according to Ludwig's classification using standardized global photography in all six views and trichoscopy for hair density and diameter.

Purpose: To study the effectiveness and safety of upper and lower eyelid treatment with combined application of three modes of 2940-nm erbium-doped yttrium aluminium garnet (Er:YAG) and 1064-nm neodymium-doped yttrium aluminium garnet (Nd:YAG) lasers in patients with baggy eyelids (formed by intraorbital fat herniation) who exhibited meibomian gland dysfunction (MGD).

Patients And Methods: In this prospective cohort study, patients with baggy eyelid who exhibited MGD received combined laser treatment at baseline, as well as at the 4-, 8-, and 12-week follow-ups. The primary endpoint was meibum quality score at 16- and 24-week follow-ups; secondary endpoints were ocular surface index scores, tear film lipid layer thicknesses, tear break up times (TBUTs), Oxford scheme grades, and meibography grades at 16- and 24-week follow-ups.

We evaluated the efficacy and safety of red light LED as an adjuvant treatment for epidermal growth factor receptor inhibitor-induced paronychia. Eight patients were recruited in this randomized, single-blinded controlled trial. They were randomized to receive red-light on one hand or foot 2-3 times/week for 6 weeks while the contralateral side served as controls.

: We sought to evaluate the efficacy and safety profile of an herbal extract combination comprising biochanin A, acetyl tetrapeptide-3, and ginseng extracts, and compare this to 3% minoxidil solution for the treatment of andogenetic alopecia (AGA). : A 24-week, triple-blinded, randomized controlled study was conducted in male and female subjects (N=32) with mild to moderate AGA. All were randomized to receive twice-daily, 1mL applications of the herbal extract combination or 3% minoxidil solution.

Introduction: Oral minoxidil is an antihypertensive vasodilator known to stimulate hair growth. The use of low-dose oral minoxidil for the treatment of male androgenetic alopecia (AGA) is receiving increasing attention. The aim of this study was to evaluate the efficacy and safety of oral minoxidil for the treatment of male AGA.

Frontal fibrosing alopecia (FFA) is a distinctive lymphocytic scarring alopecia with rapid increase in prevalence. Most FFA series are retrospectively reported from Caucasians with only few from Asians. The objective of this study was to characterize the clinical, trichoscopic and histopathological findings as well as treatment outcomes.

Delivering cells to desired locations in the body is needed for disease treatments, tissue repairs, and various scientific investigations such as animal models for drug development. Here, we report the solid composite material that when embedded with viable cells, can temporarily keep cells alive. Using the material, we also show the fabrication of detachable dissolvable microneedles (DMNs) that can instantly deliver viable cells into skin tissue.

Background: Platelet-rich plasma (PRP) treatment may encourage hair growth by promoting cellular maturation, differentiation, and proliferation.

Objective: The objective of this study was to evaluate the effectiveness of PRP as a treatment for androgenetic alopecia (AGA).

Materials And Methods: A literature search combined with meta-analysis was used to calculate the overall standardized mean difference (SMD) in hair density in patients treated with PRP injections in comparison with baseline and placebo treatment.

Background: Currently, low-level laser therapy (LLLT) has been approved as a new treatment for androgenetic alopecia (AGA). However, it has not been elucidated how LLLT promotes hair growth in vivo.

Objectives: To investigate the change in protein expression from dermal papilla (DP) tissues in male AGA patients after LLLT treatment using liquid chromatography tandem mass spectrometry (LC-MS/MS) analysis.

Objectives: To investigate the efficacy of pulsed-dye laser (PDL) as an adjunctive treatment for facial papulopustular eruptions from EGFR inhibitors (EGFRi).

Methods: Fourteen patients with facial acneiform eruptions were recruited. Half side of the face was randomized to receive PDL treatment while the other side served as a control.

Background: Limited data of sun protection knowledge in laser treatment patients exists therefore, preventative information should be provided by dermatologists to minimize harmful effects.

Objective: To assess sun protection knowledge-behavior and knowledge to prevent adverse events from laser therapy among patients who visited a laser clinic at a tertiary university hospital in Bangkok, Thailand.

Methods: This is a self-reported questionnaire, cross-sectional survey.

Despite its clinical features of multiple, confluent, small, whitish, smooth, and clear-demarcate papules on the neck and back, the pathogenesis of white fibrous papulosis of the neck (WFPN) is still unknown. The lesions increase progressively and do not regress over time. However, no effective treatment has yet been identified.

The utility of the ear crease sign, anterior tragal crease (ATC), as a marker of atherosclerosis is yet to be established. The intima-media thickness of the common carotid artery (IMT-CCA) has been used as a noninvasive surrogate marker for atherosclerosis. History of traditional risk factors for atherosclerosis was obtained from 147 volunteers; ear examination was also performed and venous blood was drawn for laboratory analysis.

Background And Objective: Lichen amyloidosis is characterized by amyloid deposition in the papillary dermis, presenting clinically with intensely pruritic hyperkeratotic papules. Various treatment modalities have been used but the results are generally unsatisfactory. Several studies show that non-ablative fractional lasers can be used to treat depositional diseases due to their capability of inducing transepidermal elimination of the dermal content.
