Human hair follicles switch between active and resting phases unpredictably.

A systematic approach is crucial for managing hair loss in women.

Hair and nail changes can indicate health issues, including cancer and side effects from cancer treatments.

The conclusion is that we need more effective hair loss treatments than the current ones, and these could include new drugs, gene and stem cell therapy, hormones, and scalp cooling, but they all need thorough safety testing.

Hormones, nutrition, and seasonal changes regulate hair growth cycles, with androgens extending growth phases and factors like aging and malnutrition affecting hair loss and thinning.

Minoxidil stimulates hair growth by increasing hair thickness and prolonging growth phase.

Geranium sibiricum extract helps hair grow and is more effective than minoxidil but can be toxic in high concentrations.

The study found that a specific area of the hair follicle helps start hair growth by reducing the blocking effects on certain cells and controlling growth signals.

The document explains how to identify different hair problems using a microscope.

Transit-amplifying cells are crucial for tissue repair and can contribute to cancer when they malfunction.

The document concludes that early diagnosis and treatment are crucial for children with hair loss to prevent permanent damage, although not all conditions can be effectively treated.

A new hair loss treatment uses tiny needles to deliver a drug-loaded lipid carrier, promoting hair growth more effectively than current treatments.

Different types of dog hair loss are linked to problems starting the hair growth phase and early hair cycle ending.

Most hair loss can be diagnosed with patient history and physical exam, and a few common types make up most cases.

Topical tofacitinib may grow hair better than minoxidil by increasing VEGF and reducing inflammation.

Ca_v1.2 affects hair growth and could be a target for hair loss treatments.

The document concludes that using specific tools and tests is essential for identifying the cause of hair loss and deciding on the right treatment.

Laser treatment helped regrow hair in mice by activating a key growth pathway.

Changing light exposure can affect hair growth timing in goats, possibly due to a key gene, CSDC2.

Alopecia areata, a type of hair loss, is likely an autoimmune disease with a genetic link, but its exact cause is still unknown.

Alopecia Areata is an autoimmune disease affecting hair follicles, influenced by genetic and environmental factors, with rodent models being essential for research.

Minoxidil prolongs cell life, slows aging, and may produce longer hairs.

Mouse skin color ranges from pink to black, depending on their hair growth cycle.

Hair gets thinner, grayer, and changes texture with age due to genetics, environment, and cellular changes, affecting the growth cycle.

The research identified genes and pathways important for sheep wool growth and shedding.

Horizontal scalp biopsy sections are better for diagnosing alopecia areata, showing fewer hair follicles and more miniaturized hairs.

Genes related to pigmentation, body rhythms, and behavior change during hares' seasonal coat color transition, with a common genetic mechanism in two hare species.

Certain proteins and their receptors are more active during the growth phase of human hair and could be targeted to treat hair disorders.

The article concludes that hair loss is a common side effect of drugs treating skin cancer by blocking the hedgehog pathway, but treatment should continue, and more selective drugs might prevent this side effect.
