Future hair loss treatments should aim to extend hair growth, reactivate resting follicles, reverse shrinkage, and possibly create new follicles, with gene therapy showing promise.

Hair growth and pigmentation in mice involve specific stages crucial for research.

Skin needs dermal β-catenin activity for hair growth and skin cell multiplication.

Iron deficiency may be related to hair loss, but there's not enough evidence to recommend iron screening or supplements for all hair loss patients.

Metformin helps manage polycystic ovary syndrome by improving insulin resistance and ovulation, but more research is needed on its full effects.

A gene called APCDD1, which controls hair growth, is found to be faulty in a type of hair loss called hereditary hypotrichosis simplex.

Researchers found 19 genes important for root hair growth in a plant called Arabidopsis.

Androgens can help prevent memory problems caused by apoE4.

Certain mutations in a hair growth-related gene cause a type of genetic hair loss.

Oestrogens are key for bone growth during puberty in both boys and girls.

Some medicinal plants can help heal wounds and may lead to new treatments.

CDP is crucial for lung and hair follicle cell development.

Blood vessels and specific genes help turn cartilage into bone when bones heal.

Blocking JAK-STAT signaling can lead to hair growth.

Androgens can cause hair growth in some areas and hair loss on the scalp.

Tight junctions are key for skin protection and controlling what gets absorbed or passes through the skin.

Male pattern baldness involves genetics, hormones, and needs better treatments.

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

Congenital Adrenal Hyperplasia is a genetic disorder with two forms, causing symptoms like early puberty and severe acne, but can be identified through screening and treated with glucocorticoids.

Alopecia areata is an autoimmune disease causing patchy hair loss, often with other autoimmune disorders, but its exact causes are unknown.

Cathepsin L is essential for normal hair growth and development.

The Sonic hedgehog pathway is crucial for new hair growth during mouse skin healing.

Male hormones affect COVID-19 severity and certain drugs targeting these hormones could help reduce the risk.

Sonic hedgehog signaling is crucial for hair growth and maintaining hair follicle identity.

Matriptase is crucial for keeping epithelial tissues healthy and functioning properly.

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.

Damage to skin releases dsRNA, which activates TLR3 and helps in skin and hair follicle regeneration.

Hair analysis can detect cocaine use but doesn't accurately show the amount or timing of use.

Men generally have more severe COVID-19 cases and higher death rates than women due to biological differences.

Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.
