Autophagy is important for human hair growth and health.

Hair greying is linked to reduced ATM protein in hair cells, which protects against stress and damage.

N-acetyl-GED may help prevent and partially reverse a process that leads to scarring hair loss.

Chemotherapy causes hair loss by damaging hair follicles and stem cells, with more research needed for prevention and treatment.

Human hair follicles can be used to create heart muscle cells.

Hair follicles can help wounds heal faster and this knowledge could be used to treat chronic skin ulcers, with a potential use of a special stem cell hydrogel to enhance healing.

Androgenetic alopecia is a common hair loss condition caused by testosterone effects on hair follicles, leading to thinner, shorter, and less pigmented hair, diagnosed using scalp dermoscopy and treated with topical minoxidil, antiandrogen agents, and 5-alpha reductase inhibitors.

Androgens can both increase body hair and cause scalp hair loss.

Beard hair extraction improves scalp hair restoration results in East Asian men with severe hair loss.

Advanced male pattern baldness affects the back of the scalp, reducing hair follicles.

Bimatoprost, a glaucoma medication, may also help treat hair loss.

Beard cells, unlike scalp cells, produce growth factors in response to testosterone, which may explain differences in hair growth.

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

The study found average numbers for different types of hair follicles in the scalp and observed differences between men and women, suggesting reasons for more common hair shedding in women.

Actual harvested hair follicles were fewer and differed in type from estimated, with older patients and those with multiple transplants needing more careful planning.

The study concluded that certain areas of the scalp and beard are safe for hair transplant donor sites in Indian men.

Alopecia areata is an autoimmune condition causing patchy hair loss, with treatments focusing on immune system regulation and hair regrowth.

Minoxidil can increase hair density, speed up regrowth in transplanted hair, and slow down further hair loss, especially beneficial for women, young men with thinning hair, and those wanting to reconstruct the back of the scalp.

Overactivating Hedgehog signaling makes hair follicle cells in mice grow hair faster and create more follicles.

A new model using mice with human hair follicles helps better understand hair loss from chemotherapy.

Childhood hair and scalp disorders can be managed with treatments like cortisone and corticosteroids.

The document explains how hair follicles develop, their structure, and how they grow.

Women with lupus experienced non-scarring hair loss with fewer hair follicles, and the test for lupus in hair was not helpful.

Male pattern baldness may be caused by scalp pressure on hair follicles, which increases with age and leads to a cycle of hair loss. This process is not directly determined by genes.

A woman's hair loss, resembling an autoimmune condition, improved after treatment, but requires ongoing checks due to potential serious associations.

Androgens can both promote and prevent hair growth due to differences in gene expression in hair follicles.

Prolactin may affect hair growth differently based on gender and scalp area.

A woman's total hair loss was linked to a Borrelia infection and was reversed with appropriate treatment.

Hair loss happens due to faster cell growth and fewer cells in affected follicles.

The study found that two enzymes linked to hair loss are located in different parts of the scalp, supporting a common treatment's effectiveness.
