Chemotherapy causes complex changes in hair follicle cells that can lead to hair loss.

Apoptosis is essential for human skin development and forming a functional epidermis.

Capsaicin, found in chili peppers, can slow down hair growth by affecting skin cells and hair follicles.

Human hair follicle organ culture is a useful model for hair research with potential for studying hair biology and testing treatments.

Tianeptine, an antidepressant, may prevent stress-induced hair loss in mice.

Cathepsin L is essential for normal hair growth and development.

Cytotoxic T cells cause hair loss in chronic alopecia areata.

Both main and alternative Wnt signaling are important for regrowing rodent whisker follicles.

Understanding how hair follicle stem cells work can help find new ways to prevent hair loss and promote hair growth.

Immune cells affect hair growth and could lead to new hair loss treatments.

IGF-1 injections help mice grow more hair by increasing cell growth and blocking a hair growth inhibitor.

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.

Future hair loss treatments should aim to extend hair growth, reactivate resting follicles, reverse shrinkage, and possibly create new follicles, with gene therapy showing promise.

Testosterone can both promote hair growth and cause baldness by affecting hair growth signals.

Low ERCC3 gene activity is linked to non-pigmented hair growth.

The review concludes that accurate diagnosis of different types of hair loss requires proper biopsy techniques and understanding the hair growth cycle and underlying causes.

Alopecia Areata is an autoimmune condition causing hair loss with no cure and treatments that often don't work well.

The study mapped yak skin cells to understand hair growth better.

Human skin has multiple layers and functions, with key roles in protection, temperature control, and appearance.

Blood tests can help understand the genetic differences in people with alopecia areata, including how severe it is and if it's inherited.

Radiation therapy damages skin structure and immune function, causing inflammation and potential hair loss.

The document discusses how traditional Chinese medicine extracts may affect hair growth in animals but lacks detailed results.

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

A systematic approach is crucial for managing hair loss in women.

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 health is influenced by genetics, aging, and environmental factors, with proper care needed to maintain it.

We need better treatments for hair loss, and while test-tube methods are helpful, they can't fully replace animal tests for evaluating new hair growth treatments.

The document describes how to tell different types of non-scarring hair loss apart by looking at hair and scalp tissue under a microscope.

Alopecia Areata is a complex, unpredictable autoimmune hair loss condition with limited treatment options and a significant psychological impact.
