Nanotechnology improves hair care products by enhancing ingredient stability, targeting treatment, and reducing side effects, but more research on its toxicity is needed.

Hair loss in males involves inflammation, collagen buildup, and follicle damage, with severity increasing with age and baldness duration.

Different hair protein amounts change the strength of keratin/chitosan gels, useful for making predictable tissue engineering materials.

Skin aging is largely due to differences in stiffness and elasticity between skin layers, leading to wrinkles.

FUE provides minimal scarring and quick recovery in hair transplantation, and surgeons not using it may lag in technology.

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

Changes in keratin make hair follicles stiffer.

The skin is the largest organ, protecting the body, regulating temperature, and producing hormones.

The gelatin/β-TCP scaffold with nanoparticles improves wound healing and skin regeneration.

Using fat stem cells and blood cell-rich plasma together improves healing in diabetic wounds by affecting cell signaling.

Micropigmentation is a widely accepted tattooing technique for hiding cosmetic issues and medical uses, with permanent results and few side effects, but risks infection if not done with sterile tools.

EVG staining is a valuable, simple, and cost-effective method for diagnosing various skin conditions in dermatopathology.

Men's hair loss is caused by hormones and genes, and can be treated with medication and surgery, while graying is due to aging and has no prevention except dyeing.

A gene in Arabidopsis thaliana, AtPRPL1, affects root hair length but not cell wall composition.

Hair follicle hyperplasia is common in both benign and malignant skin lymphoproliferative disorders, with a proposed new term "pseudolymphomatous adnexitis."

Hair loss in mice starts with immune cells damaging hair roots before it becomes visible.

Early diagnosis and treatment are crucial for preventing permanent hair loss in various scalp conditions, and while new treatments are promising, more research is needed to evaluate their effectiveness.

ROXY proteins help plants respond to nitrate shortage by affecting nutrient sensing and growth.

Bleaching hair removes its protective top layer and exposes more hydrophilic groups, changing its chemical surface and affecting how it interacts with products.

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.

Older adults commonly experience wrinkles, itchy skin, psoriasis, fungal infections, skin growths, grey hair, hair loss, and nail ridging, but no skin cancer was found in this group.

The document explains hair biology, the causes of hair loss, and reviews various hair loss treatments.

Mice can correct hair follicle orientation without certain genes, but proper overall alignment needs those genes.

Type I interferons play a key role in the development of various skin diseases.

Loss of keratin K2 causes skin problems and inflammation.

Fetal wounds heal without scarring because of different biological factors, which could help improve adult wound healing.

Two specific hair keratin genes are active during hair growth and decline as hair transitions to rest.

Loose anagen hair syndrome is caused by structural abnormalities in the hair follicle's inner root sheath.

The study concluded that PKP1 is essential for skin integrity and hair growth, and its dysfunction causes the symptoms of ectodermal dysplasia/skin fragility syndrome.

The model suggests that scalp tension could lead to hair loss, with factors like blood vessel hardening, enlarged oil glands, and poor microcirculation also playing a role. It also hints at a possible link between skull shape and baldness pattern.
