Six new genetic regions linked to early hair loss also connect to Parkinson's disease and prostate cancer, possibly leading to new treatments.

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

Different types of skin pores should be identified correctly and evaluated with suitable methods for reliable results.

Older adults have a high rate of skin cancers like basal cell carcinoma and melanoma, mainly due to UV exposure and age.

Skin changes can help diagnose and manage endocrine disorders like thyroid problems, diabetes, and adrenal gland conditions.

To diagnose hair loss, use a systematic approach including history, exams, and tests.

Trichoscopy is a useful non-invasive method for diagnosing different hair loss conditions.

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.

Feather growth and regeneration involve complex patterns, stem cells, and evolutionary insights.

Phospholipase A2 is necessary for the correct placement of PIN proteins in plant roots, affecting root growth.

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

EGF and KGF signalling prevent hair follicle formation and promote skin cell development in mice.

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

The tumor suppressor gene FLCN affects mitochondrial function and energy use in cells.

Memantine may slightly improve memory in people with Down syndrome, but more research is needed.

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

Activin helps skin growth and healing mainly through stromal cells and affects keratinocytes based on its amount.

New methods have greatly improved our understanding of stem cell behavior and roles in the body.

Mice without the Sept4/ARTS gene heal wounds better due to more stem cells that don't die easily.

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.

Muscles and nerves that cause goosebumps also help control hair growth.

Environmental factors, hormones, nutrition, and stress all significantly affect skin health and aging.

Researchers created a fully functional, bioengineered skin system with hair from stem cells that successfully integrated when transplanted into mice.

The three estrogen receptor genes are highly expressed in zebrafish neuromasts during development.

YAP and TAZ proteins are necessary for the development of two types of skin cancer.

The document concludes that proper diagnosis and FDA-approved treatments for different types of hair loss exist, but treatments for severe cases often fail and future improvements may focus on hair follicle stem cells.

Hormones, especially androgens, play a key role in acne, which can be a symptom of systemic diseases like PCOS and may require targeted treatment.

Certain mice without specific receptors or mast cells don't lose hair from stress.

The circadian clock influences the behavior and regeneration of stem cells in the body.
