Topical diphencyprone helped regrow hair in mice and rats with a condition similar to human hair loss.
research Is Thyrotropin-Releasing Hormone a Novel Neuroendocrine Modulator of Keratin Expression in Human Skin?
Thyrotropin-releasing hormone may help control skin and hair growth and could aid in treating related disorders.
research MAD2B Acts as a Negative Regulatory Partner of TCF4 on Proliferation in Human Dermal Papilla Cells
MAD2B slows down the growth of skin cells that are important for hair development by interacting with TCF4.
research P33: Experimental Advances in Hair Restoration Surgery
Hair transplant surgeries can be improved by preserving follicles in a special solution, and surgeries done at outpatient facilities are more profitable than those at hospitals.
research Keratin 71 Mutations: From Water Dogs to Woolly Hair
A mutation in the KRT71 gene causes a hair disorder by disrupting hair follicle structure and texture.
research Hair Growth and Protection Properties of an Oligosaccharide and Peptidic Extract from Maca Root
Maca root extract protects hair follicles and promotes hair growth.
research Wnt/β-Catenin and ERK Pathway Activation: The Possible Mechanism of Various LED Light Regulating the Proliferation of Human Outer Root Sheath Cells

AIRE protein, defective in APECED patients, is found in skin and hair cells and interacts with cytokeratin 17.
research Human Skin Color: Origin, Variation, and Significance
Human skin and hair color variation is mainly due to melanin produced by a few genes, with melanin protecting against sun damage.
research Blue Light Stimulatory Effect on Hair Growth Mediated by Opsin and Cryptochrome Photoreceptors
Blue light can help hair grow by affecting certain receptors in hair follicles.
research Hair Today, Gone Tomorrow: Potential of Tofacitinib and Ruxolitinib in Treating Hair Loss
Two drugs, tofacitinib and ruxolitinib, may help regrow hair by activating hair follicles.
research Mechanisms of Hair Graying: Incomplete Melanocyte Stem Cell Maintenance in the Niche
Hair graying is caused by the loss of pigment cells due to poor maintenance of stem cells in the hair follicle.
research Hair Diseases: Alopecia Areata and Androgenetic Alopecia
Alopecia areata, a type of hair loss, may be passed through T cells and has genetic links, while treatments vary in effectiveness. Male pattern baldness can be treated with finasteride and is influenced by androgens in hair follicles.
research Dermal Papilla Cell Number Specifies Hair Size, Shape, and Cycling, and Its Reduction Causes Follicular Decline
More dermal papilla cells in hair follicles lead to larger, healthier hair, while fewer cells cause hair thinning and loss.
research Quantitative Models for the Study of Hair Growth In Vivo
The conclusion is that small hair follicles cause baldness in macaques, and treatments like antiandrogens and minoxidil can prevent hair loss and promote regrowth.
