Skin problems can be caused or worsened by physical forces and pressure on the skin.

The conclusion is that tissue structure is key for stem cell communication and maintaining healthy tissues.

Skin cell behavior is influenced by the tightness of nearby cells, affecting their growth and development.

Elderly abuse is often by family members, and doctors, especially dermatologists, can spot it by looking for unusual injuries and malnutrition.

The microenvironment, especially mechanical forces, plays a crucial role in hair growth and could lead to new treatments for hair loss.

The model shows that factors like follicle shape and stiffness are key for hair growth and anchoring.

The document explains how shampoos clean, rinses condition, one-step shampoos offer convenience, and hair growth promoters aim to prevent hair loss, emphasizing the importance of scientific evidence for their effectiveness.

Wound healing insights can improve regenerative medicine.

Skin grafts are effective for chronic leg ulcers, especially autologous split-thickness grafts for venous ulcers, but more data is needed for diabetic ulcers.

Healthy scalp leads to better hair quality and less damage.

The cornified envelope is crucial for skin's barrier function and involves key proteins and genetic factors.

Mechanical trauma like towel drying can cause knotted hair even in straight hair.

The most common cause of hair loss in children is tinea capitis, followed by alopecia areata and telogen effluvium.

Researchers created early-stage hair-like structures from skin cells, showing how these cells can self-organize, but more is needed for complete hair growth.

Permanent hair dyes use chemicals that react with hydrogen peroxide to create color.

PlacMA hydrogels from human placenta are versatile and useful for cell culture and tissue engineering.

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

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

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.

Skin has specialized touch receptors that can tell different sensations apart.

Certain immune system proteins are important for skin healing but can cause problems if there are too many of them.

Children's hair grows in different types from before birth through puberty, with growth rates and characteristics varying by age, sex, and race.

Testosterone may worsen hair loss by affecting hair growth signals, while different prostaglandins can either hinder or promote hair growth.

Herbal lotions are effective for severe hair loss, with a 64.8% success rate, but relapse is common and long-term management requires allergen control and possible corticosteroid use.

Electrospun matrices help regenerate skin and hair follicles using PCL and collagen scaffolds.

A specific hair protein variant increases the spread of breast cancer and is linked to worse survival rates.

Cat claws stay sharp by shedding their outer layer through microcracks formed during activities.

Skin and its underlying fat layer act together to resist mechanical stress, and reinforcing this composite structure may help more with anti-aging than just strengthening the skin alone.

Skin cells release substances important for healing and fighting infection, and understanding these could improve skin disorder treatments.
