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

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

Hair growth is influenced by hormones and goes through different phases; androgens can both promote and inhibit hair growth depending on the body area.

Humans have limited regenerative abilities, but new evidence shows the adult brain and heart can regenerate, and future treatments may improve this by mimicking stem cell environments.

3D bioprinting is advancing in plastic and reconstructive surgery, especially for creating tissues and improving surgical planning, but faces challenges like vascularization and material development.

New biofabrication technologies could lead to treatments for hair loss.

Hair follicles could be used to noninvasively monitor our body's internal clock and help identify risks for related diseases.

The circadian clock plays a key role in hair growth and its disruption can affect hair regeneration.

Androgens, like DHT, affect hair growth and treatments like finasteride may help.

Hair analysis for drugs needs a better understanding of how drugs enter hair, considering factors like hair structure and pigmentation.

The document concludes that treating androgen excess needs patience, managing expectations is important, and many drugs used are not officially approved, suggesting cosmetic options for mild cases.

The most effective treatments for hair loss are minoxidil, finasteride, PRP, and hair transplants, with steroids and immunosuppressants for autoimmune types.

Advancements in creating skin grafts with biomaterials and stem cells are promising, but more research is needed for clinical application.

Fibroblasts, cells usually linked to tissue repair, also help regenerate various organs and their ability decreases with age. Turning adult fibroblasts back to a younger state could be a new treatment approach.

Vitamin D and calcium are important for quick and effective skin wound healing.

The conclusion is that the nuclear lamina and LINC complex in skin cells respond to mechanical signals, affecting gene expression and cell differentiation, which is important for skin health and can impact skin diseases.

Too much androgen can cause hair loss; finasteride may help.

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

Ketoconazole shampoo with finasteride improves hair density in men with hair loss.

Human hair follicle stem cells can turn into multiple cell types but lose some of this ability after being grown in the lab for a long time.

Beta-caryophyllene helps improve wound healing in mice, especially in females.

Blocking Wnt signaling in young mice causes thymus shrinkage and cell loss, but recovery is possible when the block is removed.

Beta-caryophyllene, found in essential oils, helps wounds heal better in multiple ways.

Hair analysis is better than urine and blood for detecting past drug use.

Male pattern baldness involves genetics, hormones, and needs better treatments.

Permanent hair dyes use chemicals that react with hydrogen peroxide to create color.

A protein called EGFR protects hair follicle stem cells, and when it's disrupted, hair follicles can be damaged, but blocking certain pathways can restore hair growth.

Melatonin directly affects mouse hair follicles and may influence hair growth.

Vitamin D helps skin stem cells heal wounds by working with a key skin protein.

Human sweat glands have a type of stem cell that can grow well and turn into different cell types.
