Epithelial stem cells are crucial for tissue renewal and repair, and understanding them could improve treatments for damage and cancer.

The new lab-grown skin model is good for testing sunscreen's protection against DNA damage from UV light.

Zebrafish larvae are used to study and find treatments for ear cell damage because they are easier to observe and test than mammals.

CMADK reduces hair damage from bleaching and permanent waving.

Melatonin in the skin helps protect against damage from stress and UV rays, and could be used to treat certain skin conditions.

Visible light can damage skin and most sunscreens don't block it well; more research is needed on its effects and protection methods.

Hair grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.

Arctiin helps protect hair cells from damage and death caused by oxidative stress.

Resveratrol helps prevent finasteride-induced damage in male rats, improving reproductive function.

Eupafolin nanoparticles help protect skin cells from damage caused by air pollution.

Iranian veterans exposed to sulfur mustard suffer from long-term skin itching and eye damage, with some risk of skin cancer and ongoing management challenges.

Early and personalized treatment for hair loss in young people is crucial to prevent permanent damage and should include psychological support.

New technique implants pigment in scalp with less pain and damage.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

The document concludes that more research is needed to better understand and treat primary cicatricial alopecias, and suggests a possible reclassification based on molecular pathways.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Using a fractional laser can stimulate hair growth, but the intensity and duration of inflammation are crucial. Too much can cause ulcers and scarring. Lower beam energy and fewer treatments are recommended to avoid damage.

A substance called Vascular Endothelial Growth Factor can protect certain hair follicle stem cells from damage caused by androgens, suggesting a new possible treatment for hair loss.

Maintaining skin health is crucial for overall well-being and involves protecting against environmental damage and using skincare products.

Hair loss in males involves inflammation, collagen buildup, and follicle damage, with severity increasing with age and baldness duration.

New hair can grow from large wounds in mice, but less so as they age, involving reprogramming of skin cells and specific molecular pathways.

CXXC5 is a protein that controls cell growth and healing processes, and changes in its activity can lead to diseases like cancer and hair loss.

Keratins are important for skin cell health and their problems can cause diseases.

Special and immunohistochemical stains are not routinely needed for diagnosing hair disorders.

Air pollution worsens skin diseases and aging by causing inflammation and oxidative stress.

Different types of stem cells with unique roles exist in blood, skin, and intestines, and this variety is important for tissue repair.

Porphyra-334 may help reduce wrinkles and promote hair growth.

Pinus densiflora extract may help improve memory and reduce brain inflammation.

Hair proteins have weak spots in their α-helical segments.

Olive oil compounds may help prevent cancer in animals, but human results are mixed.
