Two plywood factory workers developed contact dermatitis from phenol-formaldehyde resin, a known allergen.

Careful management of blood thinners is crucial for lupus patients with APS.

Hair follicle stem cells prevent melanocyte stem cells from differentiating by controlling retinoic acid levels.

The girl likely has Loose anagen hair syndrome, which may improve on its own or with minoxidil.

PAI-2 helps in the maturation and protection of hair and nail cells.

Skin's uneven surface and hair follicles affect its stress and strain but don't change its overall strength, and help prevent the skin from peeling apart.

Scurvy still occurs today and can be diagnosed by symptoms like gum bleeding and a specific rash, confirmed by low vitamin C levels.

Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.

Aging in hair follicle stem cells leads to hair graying, thinning, and loss.

Cutting and implanting hair follicles can create finer, more natural-looking hairlines, with about half of the implanted hairs growing back.

EGF makes hair follicles grow longer but stops hair production.

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.

Ruby laser hair removal significantly reduces hair density.

The study concluded that hair growth in mice is regulated by a stable interaction between skin cell types, and disrupting this can cause hair loss.

The Hairless gene is crucial for healthy skin and hair growth.

Macrophages help regrow hair by activating stem cells using AKT/β-catenin and TNF.

Prolactin affects hair growth cycles and can cause early hair follicle regression.

Keratin 79 marks a new group of cells that are key for creating and repairing the hair follicle's structure.

Nanoparticles around 600-700 nm can effectively enter and stay in hair follicles for days, which may help in delivering drugs to specific cells.

miR-22, a type of microRNA, controls hair growth and its overproduction can cause hair loss, while its absence can speed up hair growth.

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

Hair can regrow in large wounds through a process similar to how hair forms in embryos, and understanding this could lead to new treatments for hair loss or scarring.

Dermal papillae cells, important for hair growth, come from multiple cell lines and can be formed by skin cells, regardless of their origin or hair cycle phase. These cells rarely divide, but their ability to shape tissue may contribute to their efficiency in inducing hair growth.

Sebaceous glands in male pattern hair loss patients have more lobules and might cause early hair growth phase shifts.

Special and immunohistochemical stains are not routinely needed for diagnosing hair disorders.

An 80-year-old patient grew new hair on a wound, showing that elderly people can still regenerate hair.

Excessive cell phone use may cause hair loss due to electromagnetic radiation.

Hair health depends on various factors and hair loss can significantly affect a person's well-being; understanding hair biology is key for creating effective hair care treatments.

Hair restoration surgery has evolved over time, with a focus on natural-looking results and managing patient expectations, while also considering potential complications and the lifelong progression of male pattern baldness.

Phaeodactylum tricornutum extract helps hair follicle cells grow by activating the ERK1/2 pathway.
