Hair loss in secondary syphilis is more common than thought and can be reversed with antibiotics.
research A Split Scalp Study of Single versus Double Spin Platelet-rich plasma Injections in Treatment of Female Pattern Hair Loss: Clinical Effect and Relation to Vascular Endothelial Growth Factor in PRP
Double-spin PRP is more effective for treating female hair loss than single-spin PRP.
research Protective potential of vitamin E and gamma-oryzanol composition against ultraviolet rays-induced scalp hair damage
Vitamin E and gamma-oryzanol protect hair from UV damage.
research Gas chromatography/mass spectrometry based hair steroid profiling may reveal pathogenesis in hair follicles of the scalp
Analyzing hair with this method can help understand and monitor scalp conditions and treatment effects.
research Mapping of cis-acting expression quantitative trait loci in human scalp hair follicles
Researchers identified genes in scalp hair follicles that may affect hair traits and hair loss.
research Analysis of Biological Elements of Scalp Hairs With Sem-Edx and Tem and its Application to the Hair Comparison
SEM/EDX can analyze hair elements but struggles with trace elements, limiting its forensic use.
research 460 Promotion of Hair Growth in Ex Vivo Human Scalp Hair Follicles by the Novel Ingredient Blend NUL-5: Enhancing Elastin Expression and Wnt Signaling Activation
NUL-5 may boost hair growth by improving hair follicle health and structure.
research Distribution of polyamines may be altered in different scalp regions of patients with hair loss
Hair loss patients may have different polyamine levels in various scalp areas.
research Micro-segmental analysis of the entry pathway and distribution of zolpidem in hair from different scalp regions after a single dose
Zolpidem shows up in hair from the top back of the head after one dose and fades over time, suggesting it gets into hair through blood and sweat.
research Faculty Opinions recommendation of Prostaglandin D2 inhibits hair growth and is elevated in bald scalp of men with androgenetic alopecia.
A substance called prostaglandin D2 is found more in bald scalps and it stops hair from growing. Blocking its receptor could potentially treat hair loss.
research Hair care practices and their association with scalp and hair disorders in African American girls
Certain hairstyles and less hair oil use in African American girls can lead to scalp conditions like traction alopecia and seborrheic dermatitis.
research Dopamine is a novel, direct inducer of catagen in human scalp hair folliclesin vitro
Dopamine stops hair growth and pigment production in human scalp hair follicles.
research Centella asiatica L. Urb. Extracellular Vesicle and Growth Factor Essence for Hair and Scalp Health: A 56-Day Exploratory Randomized Trial
Centella asiatica with growth factors improves hair and scalp health.
research Identification of transcriptional targets of Wnt/β-catenin signaling in dermal papilla cells of human scalp hair follicles: EP2 is a novel transcriptional target of Wnt3a
Wnt3a activates certain genes in hair follicle cells, including a newly discovered one, EP2, which may affect hair growth.
research Faculty Opinions recommendation of Prostaglandin D2 inhibits hair growth and is elevated in bald scalp of men with androgenetic alopecia.
Prostaglandin D2, found in higher levels in bald scalps, stops hair growth, suggesting that blocking its receptor could potentially treat hair loss.
research Planar cell polarity-dependent and independent functions in the emergence of tissue-scale hair follicle patterns
Mice can correct hair follicle orientation without certain genes, but proper overall alignment needs those genes.
research Successful Short-Term Hair Transplantation Results in Two Patients With Primary Scarring Alopecia of the Scalp Pretreated With Autologous Fat Grafting
Fat grafting before hair transplant may improve hair growth in scarring alopecia.
research Hair density response to photobiomodulation in canine alopecia X is measured reliably with an ordinal scale: a randomized, controlled, double-blind study
Photobiomodulation did not significantly improve hair density in dogs with alopecia X.
research The Loss of Calcium, Phosphorus, Iron, and Nitrogen in Hair from the Scalp of Women
Shampooing can affect the loss of minerals like calcium and iron from hair.
research 878 Individual variation in balance between platelet-secreted growth factors causing contradictory effects on hair follicle could potentially impact response to PRP therapy in patients with scalp hair loss
People respond differently to hair loss treatment with PRP because of individual differences in growth factors from platelets.
research Identifying novel strategies for treating human hair loss disorders: Cyclosporine A suppresses the Wnt inhibitor, SFRP1, in the dermal papilla of human scalp hair follicles
Cyclosporine A may help treat hair loss by blocking a protein that inhibits hair growth.
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 Analysis of the scalp of women with AIDS subjected to autopsy: epithelial, follicular, and immunologic aspects
AIDS may cause changes in the scalp that increase infection risk and hair loss.
research Trichoscopy
Trichoscopy is a non-invasive way to diagnose hair and scalp problems without needing hair samples.
research The measurement of haloperidol and reduced haloperidol in hair as an index of dosage history.
Hair analysis can track haloperidol dosage history.
