Hair ages due to various factors and treatments like minoxidil and finasteride can help, but more research and better public awareness are needed.

Tofacitinib helps mice grow more hair by increasing noggin and BMP4 levels, possibly better than minoxidil.

FLCN helps control iron levels in cells.

Docosahexaenoic acid (DHA) may help hair growth by promoting dermal papilla cell proliferation.

The combination of azelaic acid, minoxidil, and caffeine significantly increased the survival of skin flaps by affecting certain body channels and nitric oxide levels.

Tofacitinib helped most patients with alopecia areata regrow hair and changes in immune cells were linked to the treatment's effectiveness.

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.

Blocking Prostaglandin D₂ may help treat hair loss.

Different types of fibroblasts play specific roles in wound healing and cancer, which could help improve treatments.

Aged individuals heal wounds less effectively due to specific immune cell issues.

Janus kinase inhibitors are effective and generally safe for treating hair loss in adults with alopecia areata.

Dogs with dermatomyositis, especially Collies and Shetland Sheepdogs, need better treatments for their skin and muscle inflammation.

Melatonin affects certain genes and pathways involved in cashmere goat hair growth.

Melatonin can increase cashmere yield by altering gene expression and restarting the growth cycle early.

New treatments and diagnostic methods for various animal skin conditions showed promising results.

Women with scarring alopecia are less likely to have used hormone replacement therapy or oral contraceptives compared to those with female pattern hair loss.

Calcium signals and SHH guide the direction of feather growth in chicken skin.

Certain small molecules can help regrow hair by turning on the body's cell cleanup process.

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.

The report concludes that PCOS is mainly a condition of excess male hormones and its definition may change as new information is discovered.

Turning white fat into brown-like fat could help fight obesity and type 2 diabetes.

Dehydroepiandrosterone (DHEA) is a prohormone important for producing sex steroids and has potential health benefits.

Stem cell niches are crucial for regulating stem cell behavior and tissue health, and their decline can impact aging and cancer.

Lichen Planus is a less common condition affecting skin and mucous membranes, with various types and associated risk factors, challenging to diagnose, significantly impacts life quality, and may have a risk of cancerous changes in oral lesions.

Stem cell offspring help control their parent stem cells, affecting tissue health, healing, and cancer.

The immune system plays a key role in tissue repair, affecting both healing quality and regenerative ability.

The timing of when the gene Bmal1 is active affects aging and survival, with its absence during development, not adulthood, leading to premature aging.
