Scientists made structures that look like human hair follicles using stem cells, which could help grow hair without using actual human tissue.

MicroRNAs are important for hair growth regulation, with Dicer being crucial and Tarbp2 less significant.

Eating too much or too little vitamin A can cause hair loss.

The mTurq2-Col4a1 mouse model shows how the basement membrane develops in live mammals.

DN106212, an extract from a plant, is better at promoting hair growth than other tested substances by affecting hair growth factors and follicle development.

The document concludes that using stem cells to regenerate hair follicles could be a promising treatment for hair loss, but there are still challenges to overcome before it can be used clinically.

Epitestosterone may counteract testosterone's effects and has roles in body processes like prostate growth and hair distribution.

A new method accurately measures nine specific hormones in human blood.

Runx1 controls fat-related genes important for normal and cancer cell growth, affecting skin and hair cell behavior.

SGK3 is essential for proper hair growth and health.

Blocking Prostaglandin D₂ may help treat hair loss.

Scientists successfully created and analyzed the structure of a part of the human androgen receptor with specific modulators and a peptide to understand how it binds differently in various tissues.

Blocking Oncostatin M's role in the JAK-STAT pathway can stimulate hair growth in mice.

Lithocholic acid helps hair growth and regeneration in alopecia by activating vitamin D receptors.

Blocking Prostaglandin D₂ (PGD₂) could help treat hair loss.

Gypenosides from Gynostemma pentaphyllum were found to have anti-aging effects, increasing skin collagen and reducing wrinkles.

Double-stranded RNA activates a pathway that causes a skin protein to be expressed in the wrong place.
