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

Researchers found that hair shedding happens mostly when new hair is growing and involves a unique process.

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

Prolactin slows down hair growth in mice.

Scientists found cells in hair that are key for growth and color.

Prolactin may affect hair growth differently based on gender and scalp area.

Certain drugs can cause early hair growth in mice by affecting the nerves.

Hair growth is influenced by hormones and goes through different phases; androgens can both promote and inhibit hair growth depending on the body area.

Modified stem cells that overexpress a specific protein can improve hair growth and reduce hair abnormalities in mice.

Keratin pretreatment improves the quality of damaged hair during perming.

Mice lacking a key DNA methylation enzyme in skin cells have a lower chance of activating stem cells necessary for hair growth, leading to progressive hair loss.

Thyroid hormones are important for skin health and changes in them can affect conditions like hair loss and eczema.

Thyroid hormones affect skin texture, hair and nail growth, and can cause skin diseases related to thyroid problems.

Adding human hair to cement can make it tougher and better insulated but also more porous.

Thyroid hormone affects skin health, with too little causing rough, pale skin and too much leading to smooth, thin skin, and may also impact wound healing and skin conditions.

Certain RNA molecules are important for the development of wool follicles in sheep.

Aspartic acid at 0.75% makes perms more effective and less damaging to hair.

Nerve growth in mouse skin and hair follicles happens in stages and is closely linked to hair development.

Chemokine signaling is important for hair development.

Hormones, nutrition, and seasonal changes regulate hair growth cycles, with androgens extending growth phases and factors like aging and malnutrition affecting hair loss and thinning.

A 32-year-old man with early graying hair shows a unique pattern, suggesting more research is needed on why hair grays early.

Direct heat perms cause more damage to hair than softening heat perms.

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

The conclusion is that Fgf18 and Tgf-ß signaling could be targeted for hair loss treatments.

Children's hair grows in different types from before birth through puberty, with growth rates and characteristics varying by age, sex, and race.

Hair diversity is influenced by complex genetics and environmental factors, requiring more research for practical solutions.

Non-coding RNAs play key roles in the hair growth cycle of Angora rabbits.

Smad4 is important for healthy hair follicles because it helps produce a protein needed for hair to stick together and grow.

Animal models are crucial for learning about hair loss and finding treatments.

Some natural extracts and one hair tonic can promote hair growth in mice.
