research Dihydrotestosterone inhibits hair growth in mice by inhibiting insulin-like growth factor-I production in dermal papillae
Dihydrotestosterone (DHT) stops hair growth in mice by lowering a growth factor important for hair.
research Exploring the “brain-skin connection”: Leads and lessons from the hair follicle
Hair follicles on the scalp interact with and respond to the nervous system, influencing their own behavior and growth.
research Ultrasound Detection of Retained Hair Tracts in Hidradenitis Suppurativa
Ultrasound shows 80% of Hidradenitis Suppurativa patients have abnormal hair tracts that may worsen the condition.
research Responses of hair follicle–associated structures to loss of planar cell polarity signaling
Loss of Fz6 disrupts hair follicle and associated structures' orientation.
research Crystalline Cataract and Uncombable Hair
The study found no common cause for a girl's crystalline cataract and uncombable hair, suggesting their co-occurrence might be coincidental.
research Permanent waving and hair straightening
Thioglycolate lotions are the most popular method for permanent waving and hair straightening.
research The Ziering Whorl Classification of Scalp Hair
The conclusion is that creating natural-looking hair restoration requires replicating natural scalp whorl patterns and inserting grafts at specific angles.
research The Effect of Parathyroid Hormones on Hair Follicle Physiology: Implications for Treatment of Chemotherapy-Induced Alopecia
Parathyroid hormones are important for hair growth, but their use in treating hair loss from chemotherapy is still uncertain.
research Investigation of a non-invasive method of assessing the equine circadian clock using hair follicle cells
RNA from horse hair follicles can track circadian rhythms non-invasively.
research Changes in the sebaceous gland in patients with male pattern hair loss (androgenic alopecia)
Sebaceous glands in male pattern hair loss patients have more lobules and might cause early hair growth phase shifts.
research An update on hair restoration therapy
Hair restoration techniques like follicular unit transplant surgery and follicular unit extraction are effective, with ideal graft placement density between 20-30 units per cm². Medications like Minoxidil and Finasteride can help maintain and regrow hair.
research Biology of Human Hair: Know Your Hair to Control It
Understanding hair biology is key to developing better treatments for hair and scalp issues.
research A newly discovered linkage between proteoglycans and hair biology: decorin acts as an anagen inducer
Decorin, a protein, may help start hair growth and could be used to treat hair loss.
research Hair keratin film as a substitute device for human hair
Keratin film can effectively replace human hair for testing hair damage.
research Functionally distinct melanocyte populations revealed by reconstitution of hair follicles in mice
Only skin melanocytes, not other types, can color hair in mice.
research Acquired progressive kinking of the hair in a prepubertal boy
A 10-year-old boy had the earliest reported case of hair that became progressively kinkier but eventually returned to normal on its own.
research Genome‐wide association study identifies variants associated with hair length in Brangus cattle
Scientists found genes linked to hair length in Brangus cattle that could help breed heat-tolerant cattle.
research The latest developments in surgical hair restoration
By 2004, Follicular Unit Transplantation (FUT) was the most effective method for surgical hair restoration, while the newer Follicular Unit Extraction (FUE) had more disadvantages and was less recommended.
research “Two-Cell Assemblage” Assay: A Simple in vitro Method for Screening Hair Growth-Promoting Compounds
The "Two-Cell Assemblage" assay is a new, simple method to identify substances that may promote hair growth.
research Alopecia areata – hyperactivity of the hypothalamic–pituitary–adrenal axis is a myth?
The study found no significant difference in stress hormone levels between people with alopecia areata and healthy individuals, suggesting that the disease is not caused by an overactive stress response system.
research Stiffness of Human Hair Correlates with the Fractions of Cortical Cell Types
Hair stiffness is higher when it has more para-like cortical cells.
research TREMendous Macrophages Inhibit Hair Growth
Certain immune cells in the skin can stop hair from growing.
research Evidence of the moderating role of hair cortisol and hair cortisone in the relationship between work stress and depression symptoms among Chinese fishermen
Hair cortisol and cortisone levels may affect how work stress influences depression in Chinese fishermen.
research Hair diameter measurement methods: micrometer caliper versus phototrichogram
The phototrichogram is better for measuring hair thickness.
research Scalp hair sweating as a predictor of hair cortisol level in human compared to obesity and other confounders
Scalp hair sweating is a significant predictor of hair cortisol levels.
research Smurf2-induced degradation of SMAD2 causes inhibition of hair follicle stem cell differentiation
Increasing Smurf2 hinders hair follicle stem cell differentiation and wound healing.
research Integrative Whole-Transcriptome Sequencing Analysis of Skin Tissues with Different Coat Types in Cashmere Goats Across Stages of Hair Follicle Development
The study found that different genes are active in cashmere goats' hair growth stages, which can help improve cashmere production.
research The Intersection of Sleep and Hair Loss: A Systematic Review
Poor sleep may lead to hair loss, and hair loss may affect sleep.
research A rare pediatric case of loose anagen hair syndrome
