A woman's sudden hair loss three years after a bone marrow transplant was a sign of chronic graft-versus-host disease but improved with treatment.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Environmental factors like shared combs can spread tinea capitis, and trichoscopy helps diagnose it.

The gene Ascl4 is not necessary for the development of hair, teeth, or mammary glands.

Stem cells control their future role by changing ERK signal timing, affecting tissue regeneration and cancer.

Seborrheic dermatitis is influenced by diet, genetics, and psychological factors.

Cyclooxygenase-2 overexpression in mice skin causes hair loss like human androgenetic alopecia.

Asian patients with Frontal Fibrosing Alopecia often lose eyebrow hair and respond well to combined antiandrogen or antimalarial and topical treatments.

New methods to classify curly hair types were developed based on shape and strength.

SKPs are similar to adult skin stem cells and could help in skin repair and hair growth.

Certain signals and genes play a key role in hair growth and regeneration, and understanding these could lead to new treatments for skin regeneration.

The conclusion is that a new biopsy technique and humidity chamber help study skin mites better and suggest mite overpopulation may cause skin diseases.

Trichoscopy helps tell apart alopecia areata and trichotillomania in Asians by looking at specific hair and scalp features.

The mesenchymal stem cell-conditioned medium gel improved burn healing and hair growth in rats better than other treatments.

Secondary hairline correction surgery can be effective and satisfying when customized to the patient's needs.

Both steroids, especially cyproterone acetate, harm quail's vital organs.

Hair follicles are complex, dynamic mini-organs that help us understand cell growth, death, migration, and differentiation, as well as tissue regeneration and tumor biology.

β-catenin in the dermal papilla is crucial for normal hair growth and repair.

Ets2 gene is crucial for placental development in mice.

Hair loss and aging are caused by the breakdown of a key protein in hair stem cells.

Hair growth and pigmentation in mice involve specific stages crucial for research.

Skin stem cells help repair damage and maintain healthy skin.

More dermal papilla cells in hair follicles lead to larger, healthier hair, while fewer cells cause hair thinning and loss.

Regenerated fully functional hair follicles using stem cells, with potential for hair regrowth therapy.

The dermal papilla is crucial for hair growth and health, and understanding it could lead to new hair loss treatments.

The Sonic hedgehog pathway is crucial for new hair growth during mouse skin healing.

Different types of stem cells and their environments are key to skin repair and maintenance.

Modulating BMP activity changes the number, size, shape, and type of ectodermal organs.

Keratin 17 is crucial for early hair strength and cell survival.

Hair grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.
