Ruby laser pulses best destroy hair follicles during the growth phase and effectiveness varies with laser intensity; melanin is key for targeting, and timing treatments can improve results.

The document concludes that for hair and feather growth, it's better to target the environment around stem cells than the cells themselves.

Epidermal stem cells could lead to new treatments for skin and hair disorders.

Wnt1a-conditioned medium from stem cells helps activate cells important for hair growth and can promote hair regrowth.

Bimatoprost, a glaucoma medication, may also help treat hair loss.

Thyroid function affects skin health, with a complex interaction between the two.

Aging in hair follicle stem cells leads to hair graying, thinning, and loss.

Melanocyte stem cells are crucial for skin pigmentation and have potential in disease modeling and regenerative medicine.

Signaling pathways are crucial for hair growth in goats.

Changing light exposure can affect hair growth timing in goats, possibly due to a key gene, CSDC2.

EPR spectroscopy showed that spontaneous hair growth results in thicker skin and less pigmented hair than depilation-induced growth.

KB2115 (eprotirome) can safely extend the hair growth phase without damaging cells or changing hair color.

Visible light can improve skin disorders and hair loss, but more research is needed to understand long-term effects.

P-cadherin is important for hair growth and health, and its problems can cause hair and skin disorders.

Sex hormones, especially estradiol, can change chicken feather shapes and colors.

A mutation in the Adam10 gene causes freckle-like spots on Hairless mice.

Eating selenium-rich rice improved antioxidant activity and signs of aging in mice.

New targeted therapies for hair loss from alopecia areata show promise, with personalized treatment expected in the future.

A protein called sFRP4 from skin cells stops the development of pigment-producing cells in hair.

Porphyra-334 may help reduce wrinkles and promote hair growth.

Lower melatonin levels are linked to more skin aging.

Spin traps like PBN could protect skin from pollution and sunlight in cosmetics but need more research for safe use.

Hair follicle stem cells could be used to treat the skin condition vitiligo.

Hair health depends on various factors and hair loss can significantly affect a person's well-being; understanding hair biology is key for creating effective hair care treatments.

The study found that the hair loss condition in Cesky Fousek dogs is influenced by multiple genes affecting skin and muscle structure, fat metabolism, and immunity.

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.

Marine-derived ingredients show potential for hair health but need more human trials to confirm effectiveness.

Good nutrition may help prevent premature hair graying.

Acitretin treatment unexpectedly darkened a patient's gray hair.

Genetic analysis of rabbits identified key genes for traits like coat color, body size, and fertility.
