Steroid hormones are crucial for body functions and have various medical uses, but their misuse can lead to dependence.

Topical treatments can deliver active molecules to skin stem cells, potentially helping treat skin and hair disorders, including skin cancers and hair loss.

Chemotherapy often causes hair loss, which usually grows back within 3 to 6 months, but there's no effective treatment to prevent it.

Stem cell research and regenerative medicine have made significant advancements in treating various diseases and conditions.

Low ferritin levels can indicate iron deficiency as a cause of hair loss.

Hair follicles can be kept in RNAlater® at cool or room temperature for a week without harming RNA quality.

Biologicals are increasingly used in medicine and cosmetics, especially for skin and hair treatments, but more research is needed.

Females have higher estrogen receptor levels in hair than males, and these levels decrease in white hair compared to black hair.

Aging causes hair to gray and thin, with the timing of graying varying by race, and factors like oxidative stress and genetics can lead to hair loss.

DHEA improved brain function and behavior in old monkeys and had additional health benefits.

The regenerative medicine industry saw business growth with new partnerships, clinical trials, and financial investments.

After chemotherapy for a gestational trophoblastic tumor, normal pregnancy rates are possible, but there's a slightly higher risk of the tumor reoccurring in future pregnancies.

Postmenopausal ovary stromal cells have a unique makeup and limited steroid production, suggesting androgens come from the adrenal gland.

Scalp reduction surgery is safe and effective for certain patients with hair loss, leading to dense hair coverage and high satisfaction.

Some chemicals can permanently or temporarily remove color from skin and hair, which can be distressing and is not well-regulated in cosmetics.

NIR-II imaging effectively tracked stem cells that helped repair facial nerve defects in rats.

Scientists made a mouse that shows how a specific protein in the skin changes and affects hair growth and shape.

Air Vice-Marshal Sir Ralph Jackson significantly advanced dialysis technology in the UK.

Addressing underrepresentation in Parkinson's research is crucial for better treatments and understanding.

Modern hair restoration techniques can effectively treat hair loss and provide natural-looking results.

Chemicals and stem cells combined have advanced regenerative medicine with few safety concerns, focusing on improving techniques and treatment effectiveness.

Eczema patients have a lower skin lipid to protein ratio, older and longer-staying hospital patients are more likely to get pressure ulcers, hair loss in AGA is linked to muscle degeneration, vitamin D deficiency is common in alopecia areata and linked to its severity, standard liver tests don't effectively detect fibrosis in psoriasis patients on methotrexate, and bullous pemphigoid patients have a higher death risk but combination therapy may reduce it.

Maintaining DNA integrity in stem cells is crucial to prevent aging and cancer.

Dermal stem cells help regenerate hair follicles and heal skin wounds.

Hair growth can be induced by transplanting certain cells, but these cells lose their properties during culturing. The best cell interaction happens in a liquid medium under gravity, and using collagen doesn't help. Future research could focus on using growth factors to stimulate these cells.

Low-level Laser Therapy may help reduce inflammation, pain, and aid healing, but more research is needed to confirm its effectiveness and establish standard treatment guidelines.

Chemotherapy in the first trimester of pregnancy is risky, but in the second and third trimesters, it's generally safe with careful drug selection and timing.

People with hair loss have more androgen receptors and enzymes in certain follicles, with men and women showing different patterns.

Understanding phenotypic plasticity is crucial for developing effective cancer therapies.
