Hair problems can be caused by genetics or the environment, and treatment should focus on the cause and reducing hair damage.

Cells in hair follicles help create fat cells in the skin by releasing a protein called Sonic Hedgehog.

Scientists created tiny particles that release medicine on the skin and in hair, working better at certain pH levels and being safe for skin cells.

Aging mice have slower hair regeneration due to changes in signal balance, but the environment, not stem cell loss, controls this, suggesting treatments could focus on environmental factors.

Hair growth and health are influenced by factors like age, environment, and nutrition, and are controlled by various molecular pathways. Red light can promote hair growth, and understanding these processes can help treat hair-related diseases.

Nanozymes show promise for effective and safe cancer treatment.

Polymeric nanohydrogels show potential for skin drug delivery but have concerns like toxicity and regulatory hurdles.

Fernblock® helps protect skin cells from pollution and stress, reducing inflammation and damage.

Changing the environment around stem cells could help tissue repair, but it's hard to be precise and avoid side effects.

Extracellular vesicles are important for disease treatment and monitoring.

Wounds heal without scarring in early development but later result in scars, and studying Wnt signaling could help control scarring.

Hidradenitis suppurativa is a complex, non-infectious skin condition with no single cause, difficult to treat, and greatly affects quality of life.

Different genes and pathways are active in yak skin and hair cells, affecting hair growth and immune responses.

B cells can both help and hinder the body's defense against melanoma.

Scientists can mimic hair disorders by altering genes in lab-grown human hair follicles, but these follicles lack some features of natural ones.

Mouse spermatogenesis shows that stem cells can behave flexibly and move widely in open environments.

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.

Smart biomaterials that guide tissue repair are key for future medical treatments.

TGFβ's manipulation of inflammation and immune cells affects cancer spread, suggesting new treatment strategies and biomarkers.

Different types of fibroblasts play various roles in both healthy and diseased tissues, and understanding them better could improve treatments for fibrotic diseases.

Blocking JAK/STAT pathways can help treat hair loss from alopecia areata.

Damaged hair follicle stem cells can cause permanent hair loss, but understanding their role could lead to new treatments.

Tissue-derived extracellular vesicles are crucial for cancer diagnosis, prognosis, and treatment.

Young female Australian fur seals are losing hair due to low tyrosine and zinc levels and high pollution exposure.

Understanding phenotypic plasticity is crucial for developing effective cancer therapies.

Dormant melanoma cells in mice interact minimally with memory T cells due to a suppressive tumor environment.

Silver nanoparticles are useful in medicine and technology for their antibacterial properties and potential in drug delivery and dentistry.

Cucurbitaceae seeds, like watermelon and pumpkin, can be used in cosmetics for skin and hair benefits.

Understanding hair surface properties is key for effective hair care products.

Humans have limited regenerative abilities, but new evidence shows the adult brain and heart can regenerate, and future treatments may improve this by mimicking stem cell environments.
