Activin A and follistatin control when ear hair cells form in mice.

Activin A promotes ear hair cell development, while follistatin delays it.

LPA3 is crucial for embryo implantation and links LPA to prostaglandin signaling.

Follistatin and LIN28B together improve the ability of inner ear cells in mice to regenerate into hearing cells.

Activin A and follistatin control when hair cells develop in mouse ears.

CIP/KIP proteins help stop cell division and support hair growth.

Androgens can cause hair growth in some areas and hair loss on the scalp.

Laser device increases hair density, safe for treating hair loss in men and women.

Hormones and genetics affect hair growth and patterns, with some changes reversible and others not.

The document concludes that understanding hair follicle cell cycles is crucial for hair growth and alopecia research, and recommends specific techniques and future research directions.

Telogen effluvium is a hair loss condition with acute cases resolving quickly and chronic cases potentially lasting longer, sometimes requiring treatment.

A pulsed electrical field safely and effectively increased hair growth.

Male pattern baldness is an unintended side effect of the body's use of androgens for muscle growth, especially in those genetically prone to it.

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.

Mice that can regenerate tissue have cells that pause in the cell cycle, which is important for healing, similar to axolotls.

KIF18B is important for correctly positioning cell division machinery in skin cells, affecting hair follicle development.

Skin stem cells are maintained by signals from nearby cells and vary in their ability to renew and mature.

Annurca apple extract may protect mouse hair from damage by chemotherapy and could help treat hair loss without promoting cancer growth.

The nucleus is key in controlling skin growth and repair by coordinating signals, gene regulators, and epigenetic changes.

The guide explains how to study human and mouse sebaceous glands using various staining and imaging techniques, and emphasizes the need for standardized assessment methods.

Different types of stem cells and their environments are key to skin repair and maintenance.

Some drugs can cause hair loss or growth, but hair usually returns to normal after stopping the drug.

Latanoprost can make eyelashes longer, thicker, and darker.

Minoxidil can help grow hair in mice by making cells grow and improving hair quality. More research needed.

Hair grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.

UV radiation can help sterilize wounds and promote healing but requires careful use to avoid damaging cells.

Androgens like testosterone affect hair growth and oil production differently across body parts and individuals.

The conclusion is that small hair follicles cause baldness in macaques, and treatments like antiandrogens and minoxidil can prevent hair loss and promote regrowth.

Aminopterin was somewhat effective in acute lymphoblastic leukemia in children but did not increase survival time.

Finasteride and minoxidil together safely and effectively increase hair growth and density for androgenetic alopecia.
