Giant solitary trichoepithelioma is a rare, usually non-cancerous hair follicle tumor that can sometimes turn into skin cancer.

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

Hair growth and health are influenced by factors like age, environment, and nutrition, and are controlled by various molecular pathways. Red light can promote hair growth, and understanding these processes can help treat hair-related diseases.

A man had a non-cancerous neck tumor related to hair follicles removed with no return of the tumor.

Early attempts at using cloned cells for hair transplants failed, but 3D cell growth showed some promise.

Long-term use of minoxidil may cause hair follicles to transform into noticeable terminal hairs, leading to trichostasis spinulosa.

Human skin can provide stem cells for tissue repair and regeneration, but there are challenges in obtaining and growing these cells safely.

Retinoic acid helps change skin cells and is important for skin development and hair growth.

Overexpression of HDGF in melanocytes does not cause cancer.

Male pattern baldness is an unintended side effect of the body's use of androgens for muscle growth, especially in those genetically prone to it.

Probiotic-coated silk/alginate scaffolds help heal wounds faster and with less scarring.

A rare skin tumor with bone formation was successfully removed without recurrence.

A young woman had a rare, usually non-cancerous tumor on her face that was initially mistaken for a different condition.

The best way to treat acne is to prevent healthy skin glands from turning into acne lesions by controlling the triggers early on.

Transplanted hair follicles can change and adapt to new areas of the body, with the immune system possibly playing a role in this adjustment.

Human hair follicle organ culture is a useful model for hair research with potential for studying hair biology and testing treatments.

Prolactin contributes to hair loss by promoting hair follicle shrinkage and cell death.

Dexamethasone speeds up hair loss in mice, while cyclosporin A slows it down.

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

Estrogens generally inhibit hair growth and improve skin quality, but their exact effects on hair follicles are complex and not fully understood.

Heparan sulfate is important for hair growth, preventing new hair formation in mature skin, and controlling oil gland development.

The article concludes that developing in vitro models for human hair structures is important for research and reducing animal testing, but there are challenges like obtaining suitable samples and the models' limitations.
