Human leukocytes and beard hair follicle cells have internal daily clocks, and PER1 and PER3 genes may indicate individual circadian rhythms.

Night shift work disrupts the body's natural clock genes.

Beard and scalp hair cells have different gene expressions, which may affect beard growth characteristics.

Androgens can cause hair growth in some areas and hair loss on the scalp.

Dermal papilla cells are key for hair growth and could help us understand and treat hair loss.

Phaeodactylum tricornutum extract helps hair follicle cells grow by activating the ERK1/2 pathway.

Human beard hair medulla contains a unique and complex mix of keratins not found in other human tissues.

The p53 protein helps control hair follicle shrinking by promoting cell death in mice.

The enzyme that changes testosterone to a stronger form is mostly found in the part of the hair follicle called the dermal papilla.

Epithelial-mesenchymal interactions control hair growth cycles through specific molecular signals.

Oxidative stress contributes to hair graying and loss as we age.

The 2015 Hair Research Congress concluded that stem cells, maraviroc, and simvastatin could potentially treat Alopecia Areata, topical minoxidil, finasteride, and steroids could treat Frontal Fibrosing Alopecia, and PTGDR2 antagonists could also treat alopecia. They also found that low-level light therapy could help with hair loss, a robotic device could assist in hair extraction, and nutrition could aid hair growth. They suggested that Alopecia Areata is an inflammatory disorder, not a single disease, indicating a need for personalized treatments.

Growing hair follicles have high mitochondrial activity and ROS in specific regions, aiding hair formation.

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.

The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.

The document concludes that understanding hair and feather regeneration can help develop new regenerative medicine strategies.

Shift nurses show altered body temperature and stress hormone levels, suggesting their body clocks adjust to irregular schedules.

Understanding and tracking our body's natural daily rhythms could help improve heart health.

Shift work disrupts the body's natural clock, leading to health problems.

TGM3 is important for skin and hair structure and may help diagnose cancer.

An individual's morning or evening preference can predict changes in their body clock gene expression.

Topical tretinoin may increase beard hair density.

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

Hair grays due to oxidative stress and fewer functioning melanocytes.

Environmental factors at different levels control hair stem cell activity, which could lead to new hair growth and alopecia treatments.

Androgens can both increase and decrease hair growth in different parts of the body.

Graying hair happens due to aging and might be delayed by new treatments.

Hair transplantation effectively treats burn scar alopecia, improving self-esteem and confidence.

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

Chamaecyparis obtusa oil may help hair grow similarly to minoxidil by affecting certain growth markers and cell factors.
