Hair loss in women is genetic, diagnosed by examination and biopsy, and treated with minoxidil, finasteride, or transplantation.

The conclusion is that proper signaling is crucial for hair growth and development, and errors can lead to cancer or hair loss.

The document provides a method to classify human hair growth stages using a model with human scalp on mice, aiming to standardize hair research.

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

Lactate production is important for activating hair growth stem cells.

Researchers found 19 genes important for root hair growth in a plant called Arabidopsis.

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.

Male hormones, particularly DHT, are linked to male pattern hair loss, and treatments like finasteride can help, but they don't work for postmenopausal women's hair loss, which may have different causes.

Certain inhibitors slow down plant growth by causing early cell specialization without changing the cell development pattern.

Early development of hair, teeth, and glands involves specific signaling pathways and cellular interactions.

Dermatoscopy and videodermatoscopy are useful for diagnosing and monitoring various skin, hair, and nail conditions.

Tight junctions are key for skin protection and controlling what gets absorbed or passes through the skin.

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

The document concludes that accurate diagnosis of ichthyosis is crucial for treatment and genetic advice, and ongoing research is needed for better therapies.

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

RNAi-based biopesticides could be safe and effective for pest control with careful development and risk assessment.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

Prolactin contributes to hair loss by promoting hair follicle shrinkage and cell death.

Mice hair growth patterns get more complex with age and can change with events like pregnancy or injury.

The document concludes that understanding hair structure is key to diagnosing hair abnormalities and recommends gentle hair care for management.

Men generally have more severe COVID-19 cases and higher death rates than women due to biological differences.

Eclipta alba extract may help hair grow similarly to Minoxidil.

The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.

Animals that change color with the seasons mainly do so in response to daylight changes, but climate change is causing camouflage problems that may require evolutionary changes.

Too much Smad7 can cause serious changes in skin tissues, including problems with hair growth, thymus shrinkage, and eye development issues.

Skin's Regulatory T cells are crucial for maintaining skin health and could be targeted to treat immune-related skin diseases and cancer.

Manipulating the catagen and telogen phases of hair growth could lead to treatments for hair disorders.

We need more research to better understand human hair follicle stem cells for improved treatments for hair loss and skin cancer.

Scientists turned mouse stem cells into skin cells that can grow into skin layers and structures.
