Combined microneedling and minoxidil improves hair growth more than minoxidil alone.
research Hair care practices and structural evaluation of scalp and hair shaft parameters in African American and Caucasian women
African American women report more hair issues and use different hair care practices than Caucasian women, and have different hair and scalp characteristics.
research The effect of cilostazol, a phosphodiesterase 3 (PDE3) inhibitor, on human hair growth with the dual promoting mechanisms
Cilostazol helps hair grow by making hair root cells grow faster and changing growth factor levels.
research Intradermal injections of a hair growth factor formulation for enhancement of human hair regrowth – safety and efficacy evaluation in a first-in-man pilot clinical study
The QR 678 hair growth treatment was safe and effective for hair regrowth in men and women.
research Investigation of hair shaft in seborrheic dermatitis using atomic force microscopy
Hair from people with seborrheic dermatitis is thicker scaled, more damaged, and thinner than healthy hair, and atomic force microscopy can help monitor the condition.
research Trichoscopic Findings of Hair Loss in Koreans
The study found specific hair and scalp patterns for different types of hair loss in Koreans, noting racial differences affect diagnosis.
research Phototrichogram analysis of normal scalp hair characteristics with aging
Hair gets thinner and grayer with age, and density decreases more in men on top and in women on top and back.
research Recipient-Site Influence in Hair Transplantation
The place where hair is transplanted can change its growth rate and length but not its thickness.
research 3D bioprinting of a gelatin-alginate hydrogel for tissue-engineered hair follicle regeneration
The new 3D bioprinting method successfully regenerated hair follicles and shows promise for treating hair loss.
research Characterization of X‐linked hypohidrotic ectodermal dysplasia (XL‐HED) hair and sweat gland phenotypes using phototrichogram analysis and live confocal imaging
People with X-linked hypohidrotic ectodermal dysplasia have no sweat ducts and less, thinner hair.
research Hair follicle characteristics as early marker of Type 2 Diabetes
Hair characteristics might be early signs of Type 2 Diabetes and could help with early prevention.
research The regulatory role of the tetrapeptide A cSDKP in skin and hair physiology and the prevention of ageing effects in these tissues – a potential cosmetic role
AcSDKP may help prevent skin and hair aging and promote their growth.
research Growth and viability of Liaoning Cashmere goat hair follicles during the annual hair follicle cycle
Liaoning Cashmere goat hair follicles show synchronized growth patterns with lowest activity in May.
research Hair diameter evaluation in different regions of the safe donor area in Asian populations
Different areas of the scalp have varying hair thickness, useful for different types of hair transplant needs.
research Histology of the Human Hair Follicle
Understanding hair follicle structure is key for treating hair disorders and could help develop new treatments.
research A Novel Follicular Unit Excision Device for All-Purpose Hair Graft Harvesting
The new hair graft device is faster, more efficient, and reduces damage to hair follicles.
research Significant relationship between temporal hair loss and other scalp areas in female pattern hair loss
Temporal hair loss relates to overall scalp hair loss in women.
research Hair shaft structures in EDAR induced ectodermal dysplasia
The EDAR gene mutation leads to thinner and more deformed hair shafts.
research Accelerated hair growth by combining thread monofilament and minoxidil in female androgenetic alopecia
Thread monofilament and minoxidil together increase hair growth in female androgenetic alopecia.
research Cornu cervi pantotrichum Pharmacopuncture Solution Facilitate Hair Growth in C57BL/6 Mice
Cornu cervi pantotrichum pharmacopuncture solution helps mice grow hair by increasing hair follicle cell growth and a growth factor important for hair development.
research Lonely Hair Sign: Not Specific for Frontal Fibrosing Alopecia
Hair diameter diversity is a key sign for diagnosing and managing male pattern baldness.
research Hair Growth-Promoting Mechanisms of Red Ginseng Extract through Stimulating Dermal Papilla Cell Proliferation and Enhancing Skin Health
Red Ginseng Extract helps hair grow and improves skin health by stimulating cell growth and enhancing the body's antioxidant defense system.

Fermented red ginseng and a traditional herb mix improved hair growth in mice.
research The Development and Application of the Hair Diameter Index (HDI)
The Hair Diameter Index (HDI) was created to help plan hair restoration surgery after finding that visual hair density is linked to hair count and thickness, not volume.
research Improvement of Hair Graying during a Treatment of Male Pattern Hair Loss Using 1,927-nm Fractionated Thulium Laser Energy and Polydeoxyribonucleotide Injections
A treatment combining laser energy and injections improved hair loss and unexpectedly also reduced hair graying.
