660-690 / 1000+ resultsresearch 원저 : 모발염색으로 인한 각피의 손상과 재생 : 시간 경과에 따른 형태학적 변화
Wait at least 8 weeks between hair dyeing for cuticle recovery.
research Permanent Hair Waving
Permanent hair waving uses chemicals to create long-lasting curls.
research Enzymatic synthesis of biosafe hematoxylin dyes on hair: enhanced post-dyeing hair health and boosting color fastness
This eco-friendly hair dye method improves hair health and color durability.
research A clinical evaluation of a permanent hair dye designed to reduce allergic contact dermatitis and hair damage
The ammonia-free hair dye is safe and improves hair shine, color, moisture, porosity, and combability.
research Hair Colours/Dyes
Natural plant-based substances can be used as effective hair dyes.
research New method of dyeing keratin fibers using poly(ethylene imine) and its coloring mechanism
A new method using poly(ethylene imine) improves hair dyeing at lower temperatures with better color retention.
research Permeant lipophilicity and vehicle composition influence accumulation of dyes in hair follicles of human skin
Lipophilic dyes accumulate more in hair follicles when delivered with surfactant-propylene glycol solutions.
research 영구염모제로 처리한 흰 모발과 흑갈색 모발의 구성 원소성분 변화
Permanent hair dye reduces sulfur content in both gray and black-brown hair.
research Preparation and Evaluation of One Stage and Two Stage Polyherbal Hair Dye Formulations
Herbal hair dyes using plants like henna and beetroot are safer and can produce varied colors, with two-stage applications giving darker shades.
research Metal-Chelation-Assisted Deposition of Polydopamine on Human Hair: A Ready-to-Use Eumelanin-Based Hair Dyeing Methodology
Polydopamine is a safe, effective, and permanent hair dye that turns gray hair black in one hour.
research Dyeing behaviours of amino heterocyclic compounds as blue oxidative hair dye precursors applied to keratin fibres
1,2,3,4-tetrahydroquinoline compounds are great for stable, pure blue hair dye.
research Analysis of keratin films as screening tools for predicting the efficacy of potential hair dyes
Translucent keratin films are better for testing hair dyes.
research On Pathways for Small Molecules Into and Out of Human Hair Fibers
Dye enters hair at the edges of cuticle cells and penetrates more from water than alcohol-based solutions.
research In vitro evaluation of changes of hair fibers subjected to oxidation-reductive straighteners associated with dyeing
Straightening and dyeing damage hair structure.
research 13B “Temporary” Scalp Micropigmentation (Trichopigmentation)
Temporary scalp trichopigmentation creates a shaved hair look on the scalp using pigments that fade over time.
research Long-term toxicity studies on oxidation hair dyes
The hair dye formulations tested did not cause long-term toxicity or cancer in mice.
research Hair colouring systems delivering colour with reduced fibre damage
Using chelants in hair dye reduces fiber damage by preventing harmful radicals.
research The Development of Squid Ink Melanin Nanoparticles as a Multifunctional Colorant Anchored on Hair Fibers: Preparation, Physicochemical Characterization and Dyeing Performance
Squid ink melanin nanoparticles create a safe, long-lasting black hair dye that protects hair and offers UV protection.
research Percutaneous penetration of hair dyes
Hair dyes penetrate the scalp very minimally, less than 1%.
research Fiber-Safe Extraction of Red Mordant Dyes from Hair Fibers
A new method extracts red dyes from wool without damaging it, although it slightly weakens the wool.
research In vitro and in vivo study of dye diffusion into the human skin and hair follicles
Dyes can penetrate human skin and hair follicles up to 1.2 mm deep and the sebaceous gland can store dye; Indocyanine Green lotion was made for safe dyeing and monitoring.
research Fiber-Safe Extraction of Red Mordant Dyes from Hair Fibers
Researchers developed a less damaging way to extract red dyes from wool using EDTA and DMF, preserving the fiber's strength for further analysis.
research Protective effect of conditioner agents on hair treated with oxidative hair dye
Conditioners in hair dye reduce damage and improve combability.
research Nanoparticles in hair dyes
Nanoparticles could make hair dyes safer by reducing harmful effects.
research 275 Nonpigmented hair removal using photodynamic therapy
Photodynamic therapy can potentially remove nonpigmented hair by damaging hair follicles.
research Investigation of hair dye deposition, hair color loss, and hair damage during multiple oxidative dyeing and shampooing cycles.
Repeated dyeing and shampooing cause hair color loss and damage.
research Modern hair coloring methods and safety-oriented color trends in 2026
Hair coloring in 2026 requires precise science and safe techniques.
