Hair loss in children can be caused by fungal infections, trauma, autoimmune disorders, or stress, and treatments vary depending on the cause.

TRPA1 is crucial for mechanical sensitivity in skin sensory neurons.

The skin is a complex barrier for drug penetration, but understanding its structure and interactions can improve drug delivery methods.

Hair follicle dermal stem cells are key for regenerating parts of the hair follicle and determining hair type.

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.

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.

K6hf is a unique protein found only in a specific layer of hair follicles.

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.

Postinflammatory hyperpigmentation causes dark skin patches and needs personalized treatment.

Melatonin helps regulate hair growth and protects the hair follicle from stress.

Laminin-511 is crucial for early hair growth and maintaining important hair development signals.

Human beard hair medulla contains a unique and complex mix of keratins not found in other human tissues.

Mammals might fail to regenerate not because they lack the right cells, but because of how cells respond to their surroundings, and changing this environment could enhance regeneration.

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

Skin has specialized touch receptors that can tell different sensations apart.

Hair shedding is an active process that could be targeted to treat hair loss.

The document concludes that various clinical methods are used to assess ageing skin and the effectiveness of anti-ageing products.

Stress hormone corticosterone blocks a growth factor to slow down hair stem cell activity and hair growth.

The 190-kbp domain contains all human type I hair keratin genes, showing their organization and evolution.

Dermal exosomes with miR-218-5p boost hair growth by controlling β-catenin signaling.

Brain hormones significantly affect hair color and could potentially be used to prevent or reverse grey hair.

Platelet-rich plasma, taken from a person's own blood, can help rejuvenate skin, stimulate hair growth, and treat hair loss, but more research is needed to confirm its safety and effectiveness.

Keratins are important for skin cell health and their problems can cause diseases.

Skin bacteria, specifically Staphylococcus aureus, help in wound healing and hair growth by using IL-1β signaling. Using antibiotics on skin wounds can slow down this natural healing process.

Glutamine metabolism affects hair stem cell maintenance and their ability to change back to stem cells.

New treatments for severe hair loss often fail, but some patients see hair regrowth with specific therapies, and treatment should be tailored to the individual's situation.

Mice can grow new hair follicles after skin wounds through a process not involving existing hair stem cells, but requiring more research to understand fully.

TGF-β2 plays a key role in human hair growth and development.

Pseudopelade of Brocq is a unique hair loss condition, but its cause and development are still not fully understood.
