research Hair removal using a long-pulsed alexandrite laser.
The long-pulsed alexandrite laser is effective for hair reduction, particularly for light-skinned individuals with dark hair, but caution is needed for darker skin.
research Electron paramagnetic resonance (EPR) spectroscopy for investigating murine telogen skin after spontaneous or depilation-induced hair growth
EPR spectroscopy showed that spontaneous hair growth results in thicker skin and less pigmented hair than depilation-induced growth.
research What Ages Hair?
Hair aging and loss are caused by genetics, hormones, environment, and grooming, with treatments like minoxidil effective for certain types of hair loss.
research Loss of ‘Epidermal Melanin Unit’ Integrity in Human Skin During Melanoma-Genesis
Melanoma development can be linked to the breakdown of skin's melanin-producing units.
research 3,4,5-Tri-O-Caffeoylquinic Acid Promoted Hair Pigmentation Through β-Catenin and Its Target Genes
A substance called TCQA could potentially darken hair by activating certain genes and increasing melanin.
research Environmental and Cosmetic Factors in Hair Loss and Destruction
Environmental and cosmetic factors, including heat, chemicals, and sun exposure, can cause hair loss and damage.
research Hair coat characteristics in Friesian heifers in the Netherlands and Kenya : experimental data and a review of literature
Friesian heifers take about 18 months to adapt to Kenya's climate, with hair changes not strongly linked to weight gain.
research Finasteride inhibits melanogenesis through regulation of the adenylate cyclase in melanocytes and melanoma cells
Finasteride reduces melanin production, possibly treating hyperpigmentation and melanoma, but needs more safety research.
research Towards Best Practice in Hair Metabolomic Studies: Systematic Investigation on the Impact of Hair Length and Color
Hair color and length affect metabolite profiles in hair, so they should be considered in hair analysis.
research Epimedium brevicornum Maxim. Extract exhibits pigmentation by melanin biosynthesis and melanosome biogenesis/transfer
Epimedium extract helps increase skin pigmentation and could be a new treatment for conditions with reduced pigmentation.
research In Ovo Injection of CHIR-99021 Promotes Feather Follicle Development via Modulating the Wnt Signaling Pathway and Transcriptome in Goose Embryos (Anser cygnoides)
Injecting CHIR-99021 into goose embryos improves feather growth by changing gene activity and energy processes.
research What ages hair?
Hair aging is inevitable, but using the right hair care products can help maintain hair health.
research The Scientific Legacy of Stephen Rothman
Stephen Rothman made important discoveries in dermatology, including the use of PABA in sunscreens, but never profited from his work.
research Amino Acids, Peptides, and Proteins
The document concludes that cosmetics need biocompatible, eco-friendly ingredients due to aging populations and demand for effective products.
research Biology of melanocytes in mammals
Melanocytes are important for skin and hair color and protect the skin from UV damage.
research Perspectives and Challenges of Hair Analysis
Hair is a complex organ, and understanding its detailed structure and growth phases is crucial for analyzing substances within it.
research The Role of Topical Vitamin D in Vitiligo: A Narrative Literature Review
Topical vitamin D is effective in treating vitiligo with few side effects.
research Natural Skin Whitening Compounds: Types, Source and Mechanism of Action: A Review
Natural compounds can lighten skin by reducing melanin.
research Cosmetic Approach for Healthy and Damaged Hair
Hair can't be reliably repaired once damaged; prevention and proper product use are key to maintaining hair health.
research Assessment of scalp hair survivin in patients with premature greying of hair
Examining Survivin levels may help understand premature greying of hair.
research All sites but skin cancer incidences analyzed worldwide by sex, age, and skin type over time (1955-2007), advancing age, and UVB dose reveals important carcinogenic drivers
Cancer rates are increasing in developed countries, with estrogen, aging, low vitamin D3, and HPV infection as common causes.
research Cosmetic Approach for Healthy and Damaged Hair
Cosmetic procedures can harm hair, but damage can be minimized with knowledge and care; however, once hair is damaged, it cannot be reliably repaired.
research Human hair keratin hydrogel : fabrication, characterization and application
Keratin hydrogels from human hair show promise for tissue engineering and regenerative medicine.
research Dermal papilla regulation of hair growth and pigmentation
Dermal papilla cells are key for hair growth and color, influencing hair type and size, and their interaction with stem cells could help treat hair loss and color disorders.
research Nouvelles thérapeutiques dans la prise en charge de l’alopécie androgénétique
De nouvelles thérapies promettent de mieux traiter la perte de cheveux due à l'alopécie androgénétique.
research Associations between sun sensitive pigmentary genes and serum prostate specific antigen levels
Men with less sun-sensitive skin have lower PSA levels, while men with more sun-sensitive skin have higher PSA levels.
research Cutaneous malignant melanoma incidences analyzed worldwide by skin type over advancing age of males and females: Evidence estrogen and androgenic hair are risk factors
Estrogen and androgenic hair increase melanoma risk, especially in European-ancestry individuals.
research Pathobiology of chemotherapy-induced hair loss
Chemotherapy causes hair loss by damaging hair follicles and stem cells, with more research needed for prevention and treatment.
research PAK4 signaling in health and disease: defining the PAK4–CREB axis
PAK4 is crucial in cancer progression, brain development, and could be a therapeutic target, especially through the PAK4-CREB axis.
