Skin aging is largely due to differences in stiffness and elasticity between skin layers, leading to wrinkles.

The skin is the largest organ, protecting the body, regulating temperature, and producing hormones.

Some patients with mycosis fungoides or Sézary syndrome experience hair loss, which may be similar to alopecia areata or linked to skin lesions, possibly due to abnormal T cells, and bexarotene can help treat it.

Scientists created hair-growing skin models from stem cells, which could help treat hair loss and skin diseases.

Endo-HSE helps grow hair-like structures from human skin cells in the lab.

Human hair has a protective lipid layer that can be damaged by moisture and treatments, affecting hair growth and health.

Skin and hair can regenerate after injury due to changes in gene activity, with potential links to how cancer spreads. Future research should focus on how new hair follicles form and the processes that trigger their creation.

Type IV collagen chains vary in different parts of human skin, with specific patterns linked to melanocytes.

Forehead lifting can restore a youthful look and improve brow aesthetics using various surgical and nonsurgical methods.

Human hair follicle dermal cells can effectively replace other cells in engineered skin.

Reptile skin hardens by layering beta-proteins on keratin.

The model better predicts how water-loving and fat-loving substances move through the skin by including tiny pores and hair follicle paths.

Adiponectin boosts lipid production in skin cells, potentially helping treat skin conditions with low sebum.

Chitosan-coated nanoparticles improve skin delivery of hair loss treatments with fewer side effects.

Plet-1 protein helps hair follicle cells move and stick to tissues.

Microsporum gypseum fungus breaks down keratin in hair by digesting it enzymatically, starting with less keratinized parts.

The lipid in human hair follicles acts as a barrier, similar to the skin's lipid layer.

Fatty acid composition in human skin, mouth, and hair cells varies with keratinization, and cultured cells show essential fatty acid deficiency.

3D imaging shows clearer details of skin structure changes with age.

Ultrasound shows 80% of Hidradenitis Suppurativa patients have abnormal hair tracts that may worsen the condition.

The study found that mouse sweat glands develop before birth, mature after birth, and have specific keratin patterns.

The enzymes Aldh1a2 and Aldh1a3 are involved in making retinoic acid in hair follicles and have different roles in hair growth.
