Light can turn on hair growth cells through a nerve path starting in the eyes.

Runx genes are important for stem cell regulation and their roles in aging and disease need more research.

Estrogens significantly influence hair growth by interacting with receptors in hair follicles and may help regulate the hair growth cycle.

Alopecia areata is an autoimmune condition causing hair loss, influenced by genetics, stress, and diet, and may be prevented by a high soy oil diet.

Scientists successfully created and transplanted bioengineered hair follicles that function like natural ones, suggesting a new treatment for hair loss.

Androgens can both stimulate and cause hair loss, and understanding their effects is key to treating hair disorders.

Understanding normal hair growth and loss in children is key to diagnosing and treating hair disorders.

Too much Smad7 changes skin and hair development by breaking down a protein called β-catenin, leading to more oil glands and fewer hair follicles.

Understanding hair growth involves complex interactions between molecules and could help treat hair disorders.

Alopecia areata causes hair loss with varied treatment responses and frequent relapses.

Taxol damages hair growth cells, causing hair loss.

Dermal cells are key in controlling hair growth and could potentially be used in hair loss treatments, but more research is needed to improve hair regeneration methods.

Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Hair follicles are complex, dynamic mini-organs that help us understand cell growth, death, migration, and differentiation, as well as tissue regeneration and tumor biology.

Low-level laser treatment helps mice grow hair by increasing certain protein levels linked to hair growth.

Long scalp hair evolved for cooling and social signaling.

Hair transplant surgery can rebuild muscle and nerve connections, allowing transplanted hairs to stand up like normal hairs.

Hairless protein and putrescine regulate each other, affecting hair growth and skin balance.

Minoxidil helps hair growth by activating enzymes in hair follicles.

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.

Human skin's melanocytes respond to light by changing shape, producing pigments and hormones, which may affect sleep patterns.

Different treatments for alopecia areata have varying success rates and side effects; intralesional steroids are most effective.
