The effect of eflornithine 13.9% cream on the bother and discomfort due to hirsutism.

Although unwanted facial hair often leads to anxiety and avoidance of social situations, evaluation of treatment outcomes in clinical trials has relied largely on measures external to the patient such as the extent of hair growth or an expert physician's assessment, neglecting to include patient reported outcomes (PRO). To assess the level of bother caused by a dermatological condition (hirsutism) and changes brought on by treatment, the instrument ESTEEM was developed by expanding the Bother Assessment in Skin Conditions (BASC) scale to six questions to cover the discomfort felt in four social situations and bother due to removing facial hair. Each question elicits responses on a visual analog scale.

Differences in expression of specific biomarkers distinguish human beard from scalp dermal papilla cells.

Androgen exposure stimulates the growth of beard hair follicles. The follicle dermal papilla appears to be the site of androgen action; however, the molecular mechanisms that regulate this process are not well understood. In an attempt to identify genes that contribute to the androgen-responsive phenotype, we compared gene expression patterns in unstimulated and androgen-treated cultured human dermal papilla cells isolated from beard (androgen-sensitive) and occipital scalp (androgen-insensitive) hair follicles.

Apoptosis in the hair follicle.

Apoptosis plays an important role in many physiological processes, ranging from morphogenetic events to adult tissue homeostasis, and defects in its regulation contribute to many disorders. Here we review molecular mechanisms of apoptosis in the hair follicle (HF), whose cyclical growth pattern is repeatedly interrupted by apoptosis-driven involution (catagen). We review the common mechanisms underlying apoptosis in the HF during catagen, as well as differences in the regulation of apoptosis between distinct HF cell populations.
