UK stem-cell clinics often mislead about treatment safety and effectiveness, needing better regulation.

Cactus extract from Notocactus ottonis may help promote hair growth.

Lack or blocking of SRD5a, a key component in hormone creation, can lead to conditions like pseudohermaphrodism and affect hair growth, bone mass, muscle strength, and reproductive health. More research is needed on its regulation from fertilization to adulthood.

Melatonin receptors, found in many body parts, can help treat various diseases like depression and diabetes due to their effects on inflammation, tumor progression, sleep disorders, and body mass regulation.

The combination of certain vitamins and pumpkin seed oil has not been proven to maintain normal hair.

Stem cell niches are crucial for regulating stem cell behavior and tissue health, and their decline can impact aging and cancer.

Different processes create patterns in skin and things like hair and feathers.

Dehydroepiandrosterone (DHEA) is a prohormone important for producing sex steroids and has potential health benefits.

A new gene, JMJD1C, may affect testosterone levels in men.

Hairless protein is crucial for healthy skin and hair, and its malfunction can cause hair loss.

New drugs for heart disease may be developed from molecules secreted by stem cells.

New gene identification techniques have improved the understanding and classification of inherited hair disorders.

Bioengineered salivary glands in mice can produce saliva when tasting sour or bitter, but have different protein levels and nerve signals compared to natural glands.

Hormones control reproduction and are crucial for body balance.

NF-κB signaling is crucial in many diseases and can be targeted for new treatments.

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.

Hair follicles produce and respond to melatonin, affecting hair growth and sensitivity to estrogen.

The document concludes that for hair and feather growth, it's better to target the environment around stem cells than the cells themselves.

Eating healthy, exercising, and taking certain supplements can help manage Polycystic Ovary Syndrome symptoms.

The article suggests using four questions to tell apart necessary medicalization from excessive medicalization, focusing on problem significance, social expectations, medical understanding, and effective resolution.

Different lab conditions and light treatment methods change how human skin cells respond to light therapy.

The document concludes that understanding hair follicle cell cycles is crucial for hair growth and alopecia research, and recommends specific techniques and future research directions.

Skin and hair can regenerate after injury due to changes in gene activity, with potential links to how cancer spreads. Future research should focus on how new hair follicles form and the processes that trigger their creation.

Cell-based therapies using dermal papilla cells and adipocyte lineage cells show potential for hair regeneration.

Hairless mice lack fur due to a genetic mutation affecting skin response, not hormone issues.

Certain signals are important for reducing specific chemical markers on hair follicle stem cells during rest periods, which is necessary for healthy hair growth.

Small changes in hormones can significantly impact health, showing the importance of sensitive testing for chemicals that disrupt hormones.

The conclusion is that androgenetic alopecia and senescent alopecia have unique gene changes, suggesting different causes and potential treatments for these hair loss types.

Using neurohormones to control keratin can lead to new skin disease treatments.

Normal levels of DHT can reduce belly fat and increase muscle, but too much can lead to hair loss, prostate issues, and possibly heart disease.
