research Diseases of Periocular Hair
The document concludes that periocular hair disorders have various causes and treatments, and proper evaluation by specialists is important for management and prognosis.
research Androgenic Alopecia: Cross-Talk Between Cell Signal Transduction Pathways
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.
research Hair Graying as an Evolutionary Checkpoint against Malignancy: a Stem Cell Perspective
Hair graying may help prevent cancer by protecting stem cells.
research Uncombable hair syndrome and beyond
Uncombable hair syndrome causes frizzy hair and can affect the nervous system, eyes, and ears, often co-occurring with other hair, skin, nail, and teeth conditions, and is linked to three specific gene mutations.
research Hair Care and Cosmetics
Hair care products are important for appearance and self-esteem, and choosing the right ones can help maintain healthy hair.

A woman's hair turned gray and fell out after starting a cancer drug called imatinib mesylate.
research Preparing the hair follicle canal for hair shaft emergence
A specific type of skin cell creates an opening for hair to grow out, and problems with this process can lead to skin conditions.
research Colorimetry provides a rapid objective measurement of de novo hair growth rate in mice
Colorimetry can accurately measure hair growth rates in mice.
research Age, lifestyle and self‐perceptions of hair: Is there an association with hair diameter and tensile properties?
Older age and certain lifestyles are linked to thinner, weaker hair, while how you see your hair relates to its thickness.
