miR-22, a type of microRNA, controls hair growth and its overproduction can cause hair loss, while its absence can speed up hair growth.

Prolactin affects the production of different keratins in human hair, which could lead to new treatments for skin and hair disorders.

Cell-based therapies using dermal papilla cells and adipocyte lineage cells show potential for hair regeneration.

Hair gets thinner, grayer, and changes texture with age due to genetics, environment, and cellular changes, affecting the growth cycle.

Scientists created 3D hair-like structures that could help study hair growth and test treatments.

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

Scientists successfully created and transplanted bioengineered hair follicles that function like natural ones, suggesting a new treatment for hair loss.

Changes in the HR gene have influenced hair growth and may lead to hair loss conditions in humans.

Alopecia areata can be triggered by specific immune cells without genetic or environmental factors.

EVAL membranes help create cell structures that can regrow hair follicles.

Plant extracts may help prevent or reverse hair graying.

Mice with human skin protein K8 had more skin problems and cancer.

Skin structure complexity and variability are crucial for assessing skin toxicity in safety tests.

The proteins transthyretin and megalin are more present in the growth phase of hair, suggesting they might affect hair health and growth.

Too much Smad7 changes skin and hair development by breaking down a protein called β-catenin, leading to more oil glands and fewer hair follicles.

Understanding hair growth involves complex interactions between molecules and could help treat hair disorders.

Surgical repigmentation can permanently restore color to white hair in vitiligo patients.

Hair follicles on the scalp interact with and respond to the nervous system, influencing their own behavior and growth.

SGK3 is essential for proper hair growth and health.

The document concludes that the hair cycle is a complex process involving growth, regression, and rest phases, regulated by various molecular signals.

Mesotherapy with natural extracts and vitamins can improve hair loss and promote regrowth in most women.

Scientists found a way to grow human hair cells in a lab that can create new hair when transplanted.

The Hairless gene is crucial for healthy skin and hair growth.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Scientists can mimic hair disorders by altering genes in lab-grown human hair follicles, but these follicles lack some features of natural ones.

Too much Smad7 can cause serious changes in skin tissues, including problems with hair growth, thymus shrinkage, and eye development issues.

Urokinase, a type of protein, helps skin cells multiply faster, especially in newborn mice.

The Foxn1(-/-) nude mouse shows disrupted and expanded skin stem cell areas due to high Lhx2 levels.

Human hair follicle organ culture is a useful model for hair research with potential for studying hair biology and testing treatments.
