Hair melanocytes help the skin respond to stress and regulate hair pigmentation.

A woman with a rare hormone resistance condition also had missing teeth and hair loss, which might be new symptoms of her genetic disorder.

Bimatoprost and clobetasol are both effective for scalp hair loss, but bimatoprost works faster, has fewer side effects, and grows more colored hair.

Blocking mTORC1 activity could increase hair pigmentation and potentially reverse greying.

Prostaglandin F2alpha and related compounds can increase hair growth and darken hair in mice.

People with certain skin diseases have higher levels of the hormone prolactin in their blood.

Prostaglandin F2α analogs show promise for treating certain types of hair loss but need more research for other skin conditions.

PTH-CBD could help prevent and treat hair loss caused by chemotherapy in mice.

Nanotube-based hair treatments could improve hair health and growth, and offer long-lasting effects.

New findings suggest potential treatments for melanoma, hyperpigmentation, hair defects, and multiple sclerosis, and show skin microbiome changes don't cause atopic dermatitis.

Some cells may slow melanoma growth, a protein could affect skin pigmentation, a gene-silencing method might treat hair defects, skin bacteria changes likely result from eczema, and a defensin protein could help treat multiple sclerosis.

Minoxidil treatment can stimulate hair growth in hairless puppies if applied early.

Finding eosinophils near hair bulbs helps diagnose alopecia areata.

Different hair and scalp disorders cause hair loss or excess hair growth, with various treatments available depending on the specific condition.

The document describes how to tell different types of non-scarring hair loss apart by looking at hair and scalp tissue under a microscope.

The document concludes that accurate diagnosis of different types of hair loss requires careful examination of hair and scalp tissue, considering both clinical and microscopic features.

Other common signs, not just the well-known immune cells around hair bulbs, are important for diagnosing hair loss from alopecia areata.

The document concludes that recognizing specific histological features of different nonscarring alopecias is crucial for accurate diagnosis and understanding hair loss progression.

Alopecia areata is a common autoimmune condition causing varying hair loss, diagnosed by specific patterns of inflammation around hair follicles, with several treatment options available.

Most cutaneous adnexal tumors examined were benign and resembled common skin tumors.

Trichoscopy is a useful tool for diagnosing hair and scalp diseases without needing skin biopsies.

Wnt signaling is crucial for pigmented hair regeneration by controlling stem cell activation and differentiation.

Melanocyte stem cells in hair follicles are key for hair color and could help treat greying and pigment disorders.

Oxidative stress causes hair to gray by damaging and killing pigment cells.

Cathepsin L is essential for normal hair growth and development.

Hair graying happens because certain cells aren't maintained properly.

Melanocyte activity in hair follicles is linked to the hair growth cycle, being active in growth phases and inactive in rest phases.

The article concludes that while we understand a lot about how melanocytes age and how this can prevent cancer, there are still unanswered questions about certain pathways and genes involved.

The new assay can track and measure melanosome transfer between skin cells, confirming filopodia's role in this process.
