Male pattern baldness is a common hair loss in men caused by genetics and hormones, with treatments including drugs, hair transplants, and hair loss products.

Polydopamine is a safe, effective, and permanent hair dye that turns gray hair black in one hour.

Experts advise using sunscreen and proper skin care before, during, and after procedures to speed healing, prevent complications, and reduce scarring.

Smart hydrogel dressings could improve diabetic wound healing by adjusting to wound conditions and controlling drug release.

Nanomaterials can significantly improve wound healing and future treatments may include smart, real-time monitoring.

Abusing steroids can damage your heart, muscles, reproductive system, liver, skin, and brain, and may increase the risk of Alzheimer's disease.

Gender-affirming hormone therapy improves physical performance in trans men to the level of cisgender men, while in trans women, it increases fat mass and decreases muscle mass, with no advantage in physical performance after 2 years.

Testosterone replacement therapy helps manage deficiency and has various methods, but requires careful monitoring to avoid side effects.

Removing the ATR gene in adult mice causes rapid aging and stem cell loss.

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

Cornification is how skin cells die to form the protective outer layer of skin, hair, and nails.

Proteins with added sugars are crucial for plant root hair growth.

Targeting and modifying the stem cell niche can improve regenerative therapies.

BMAL1 controls skin cell growth and UV damage risk, peaking at night.

Stem cells help heal skin wounds by moving and changing roles, working with other cells, and needing more research on their activation and behavior.

Different types of skin cells play specific roles in development, healing, and cancer.

TGF-β is crucial for controlling stem cell behavior and changes in its signaling can lead to diseases like cancer.

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

Mouse Notch is important for determining cell roles in hair follicles.

The niche environment controls stem cell behavior and plasticity, which is important for tissue health and repair.

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

Human dermal fibroblasts are the main cells targeted by a virus that can cause a deadly skin cancer, and a certain inhibitor can effectively block this infection.

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.

Understanding how cells die in the skin is important for treating skin diseases and preventing hair loss.

Hair graying happens because certain cells aren't maintained properly.

Metabolic signals and cell shape influence how cells develop and change.

BMP signaling controls hair follicle size and cell growth by affecting cell cycle genes.

The circadian clock is crucial for tissue renewal and regeneration, affecting stem cell functions and having implications for health and disease.

Layer-by-Layer self-assembly is promising for biomedical uses like tissue engineering and cell therapy, but challenges remain in material safety and process optimization.

Stem cells in hair follicles can become various cell types, including neurons.
