Obesity is linked to more severe hair loss in adult men and to excess hair growth, but its effects on hair conditions are complex and need more research.

The document concludes that more research is needed to better understand and treat primary cicatricial alopecias, and suggests a possible reclassification based on molecular pathways.

Research on epidermal stem cells has advanced significantly, showing promise for improved clinical therapies.

TGF-β1 increases androgen receptor activity in hair loss, but Hic-5/ARA55 can counter this effect.

Men and women have different hairline restoration needs, with natural design being more complex for women, and hairline changes being important for transgender individuals' transitions.

The technique effectively restores temporal peaks in hair transplants using different hair densities and angles in three zones.

Gellan gum hydrogels help recreate the environment needed for hair growth cell function.

A new treatment using stem cell-conditioned media significantly improved hair growth in people with temporary hair loss.

To prevent thinning in the donor area, harvest less than 50% of the original hair density in repeat hair transplants.

The document concludes with the creation of a Hair Transplant Foundation after reviewing the early hair transplant techniques and discussions from a forum.

Blocking specific proteins can help remove aging cells and might treat age-related diseases and promote hair growth.

Different hair follicles in the skin are innervated by unique combinations of mechanosensory neurons, crucial for touch sensation.

Epithelial stem cells are crucial for tissue renewal and repair, and understanding them could improve treatments for damage and cancer.

Skin stem cells interacting with their environment is crucial for maintaining and regenerating skin and hair, and understanding this can help develop new treatments for skin and hair disorders.

The paper concludes that understanding melanocyte development can help in insights into skin diseases and melanoma diversity.

Hydrogel scaffolds can help wounds heal better and grow hair.

Lgr5 is a marker for active, self-renewing stem cells in the intestine and skin, important for tissue maintenance.

Certain proteins, Lgr5 and Lgr6, are important markers of adult stem cells and are involved in tissue repair and cancer development.

Polymeric nanoparticles show promise for treating skin diseases.

TGF-β is crucial for tissue repair and can cause diseases if not properly regulated.

Inactive stem cells in hair follicles and muscles can avoid detection by the immune system.

Stem cell niches support, regulate, and coordinate stem cell functions.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

Aging causes skin stem cells to work less effectively.

Skin aging is due to impaired stem cell mobilization or fewer responsive stem cells.

Different types of stem cells with unique roles exist in blood, skin, and intestines, and this variety is important for tissue repair.

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

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.

Cytokeratin 19 and cytokeratin 15 are key markers for monitoring the quality and self-renewing potential of engineered skin.
