Cicatricial alopecia, a permanent hair loss condition, is mainly caused by damage to specific hair follicle stem cells and abnormal immune responses, with gene regulator PPAR-y and lipid metabolism disorders playing significant roles.

The symposium concluded that hair growth involves complex processes, including the hair follicle life cycle, the role of the dermal papilla, hair strength, pigmentation, and the impact of diseases and treatments like minoxidil on hair and skin.

Hair follicle biology advancements may lead to better hair growth disorder treatments.

Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

MIM is crucial for hair follicle formation and regeneration by controlling cilia formation and hedgehog signaling through its interaction with Cortactin and Src.

Drosha and Dicer are essential for hair follicle health and preventing DNA damage in skin cells.

Sox2-positive dermal papilla cells have unique characteristics and contribute more to skin and hair follicle formation than Sox2-negative cells.

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

Researchers found that bulge cells from human hair can grow quickly in culture and have properties of hair follicle stem cells, which could be useful for skin treatments.

Researchers developed a method to grow hair follicle cells for transplantation using a special chip.

HPV16 oncogenes disrupt the normal activity of hair follicle stem cells.

Intu gene is crucial for hair follicle formation by helping keratinocytes differentiate through primary cilia.

Hair follicle damage happens during hair transplants and can impact success; better surgical methods are needed.

Mouse hair follicle stem cells lose their ability to change into different cell types after being grown for a long time.

Human stem cells were turned into cells similar to those that help grow hair and showed potential for hair follicle formation.

Hair loss caused by longer latent hair cycle and sudden miniaturization, not gradual follicle size reduction.

Telomere damage affects skin and hair follicle stem cells by messing up important growth signals.

IL-33 is linked to hair follicle damage in psoriasis and could be a treatment target for hair loss in this condition.

Brain-Derived Neurotrophic Factor (BDNF) slows down hair growth and promotes hair follicle regression.

Hairless HRS/J mice resist Bacillus anthracis skin infections due to high numbers of immune cells, not because they lack hair follicles.

The research suggests that p63 and TGF-β1 may help determine tumor type and malignancy in hair follicle and sebaceous tumors.

A new gene, mrp4, is found in mice and may play a unique role in hair follicle development in tails and ears.

The document concludes that accurate diagnosis of different types of hair loss requires careful examination of hair and scalp tissue, considering both clinical and microscopic features.

Laser hair removal works well for people with dark hair and light skin, but it's less effective for light hair or dark skin; improvements are expected.

Certain immune cells in the skin release a protein that stops hair growth by keeping hair stem cells inactive.

Mice lacking a key DNA methylation enzyme in skin cells have a lower chance of activating stem cells necessary for hair growth, leading to progressive hair loss.

Edar signaling is crucial for controlling hair growth and regression.

MED1 is essential for normal hair growth and maintaining hair follicle stem cells.

Effective treatment for hidradenitis suppurativa varies, with antibiotics commonly used and surgery as an option, but no single method is universally successful.
