Dutasteride more effective for hair growth, but has more side effects than finasteride.

Japanese women typically start experiencing hair loss after 40, with reduced hair density and thickness being the main factors.

Androgens slow hair growth by altering Wnt signaling in balding cells.

Pitx2 helps outer root sheath cells differentiate but can't start hair growth on its own.

Topical vitamin D3 does not prevent hair loss from chemotherapy.

The document concludes that better treatments for CCCA are needed and more research is required to understand its causes related to hairstyling and genetics.

Certain molecules in hair change with age and could be used for cosmetic treatments.

Certain immune cells contribute to severe hair loss in chronic alopecia areata, with Th17 cells possibly having a bigger impact than cytotoxic T cells.

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

Using a fractional laser can stimulate hair growth, but the intensity and duration of inflammation are crucial. Too much can cause ulcers and scarring. Lower beam energy and fewer treatments are recommended to avoid damage.

The enzyme type 1 5α-reductase is more active in the hair follicle's lower part than in the skin's outer layer.

Short telomeres contribute to aging and cancer, and while telomerase can delay aging, it may also promote cancer.

We need better treatments for hair loss, and while test-tube methods are helpful, they can't fully replace animal tests for evaluating new hair growth treatments.

Most dogs have hair whorls on their chest and limbs, with shelter dogs and short-haired dogs having more chest whorls.

Growing hairs are easier to pull out than resting hairs due to different anchorage strengths.

New steroidal compounds moderately block an enzyme related to testosterone conversion, less effectively than finasteride.

The study suggests silicon might be important for healthy hair, as less silicon was found in people with hair loss.

Researchers successfully transplanted hair follicles in mice, which survived well and helped in wound healing.

D-OCT shows increased blood vessel growth in response to tissue damage in Frontal Fibrosing Alopecia and is useful for diagnosis and monitoring.

Stopping S100A3 activity slows down hair growth in mice.

PRC1 influences skin stem cell development by both turning genes on and off, affecting hair growth and skin cell types.

Blocking JAK-STAT5 signaling in mice leads to hair growth.

The hair follicle dermal sheath is essential for hair shedding and needs to communicate with the outer root sheath for normal hair growth cycles.

Hair transplantation has improved to more natural-looking results and is complemented by effective non-surgical treatments, with ongoing research into hair follicle cloning.

Hair transplantation has improved to use smaller grafts for a natural look and may include follicle cloning in the future; non-surgical treatments are also effective.

Microspheres about 1.5 micrometers in size can best penetrate hair follicles, potentially reaching important stem cells.

Creating stronger blockers for skin enzymes might lead to better treatment for conditions like acne and excessive hair growth.

Regenerated fully functional hair follicles using stem cells, with potential for hair regrowth therapy.

Estrogens significantly influence hair growth by interacting with receptors in hair follicles and may help regulate the hair growth cycle.

Mouse hair follicle cells briefly grow during the early hair growth phase, showing that these cells are important for starting the hair cycle.
