![]() ![]() Even though small percentage were not satisfied with the outcome, they continued the use of hair dyes. ![]() Majority (86%) of them used hair dye 3-5 times a year to conceal their grey hairs. It is caused by the loss of the pigmented-forming melanocytes from the hair follicles, which reflects loss of the melanocyte stem cell population in the aging hair follicles. Greying of the scalp hair is an inevitable physiologic process in human aging. Most of them felt that temporary dyes were the safest but they were not able to substantiate it, the probable reason could be temporary dyes being large molecules do not penetrate the shaft and only coats it. ![]() Though majority of them believed that hair dyeing was not safe they continued their use even during pregnancy. Around 36% of them did not follow the instructions before the use of dyes. However they did not perform an allergy test before using it. ![]() The majority of participants, particularly the illiterates and those who used hair dyes at home, were able to mention the brand names of the product they used. However, in a study done in Riyadh, the practice began at an age as young as 15 years. The youngest volunteer using hair dye in our study was 20 years. The mean age at which both genders started hair dyeing was 27 years, while it was 16 years in a study conducted on Danish adult population and 40-49 years in Korean population. The results in our study indicate that >50% females dye their hair. Owing to increased demand the market is poised for a new scientific breakthrough to produce quick and efficient hair coloring products. Questionnaire included detailed information regarding their educational status, occupation and income, the age at which they first started using hair dyes, type of hair dyes, frequency of its use, their motives behind coloring their hair, use during pregnancy and in their children and also if they had suffered from any reactions after its use.Ĭoloring of hair signifies a major step in self-expression which has recently been influenced by innovative science. It included 28 questions regarding the use of hair dyes and required approximately 15 minutes to answer completely. Volunteers of both gender, aged above 18 years who were willing to give consent were administered a questionnaire randomly, those who were unable to understand, the questions were explained to them in local language. It was conducted for a period of 3 months from July to September 2012. Study included the patients and their attenders visiting RL Jalappa Hospital and Research Center, staff and students of Sri Devaraj Urs Medical College. This was a cross-sectional study conducted by the Department of Pharmacology. The protocol was approved by the Institutional Ethics Committee. The aim of this study was to assess the knowledge, practice, perception and adverse reactions among the hair dye users. It is mutagenic and carcinogenic but not a known teratogen. Systemic effects include angioedema, rhabdomyolysis, renal and cardiac toxicity. #HAIR DYE COLORS SKIN#It is absorbed from the skin resulting in allergic dermatitis. The alkalizing agent (aromatic amines), paraphenylenediamine (PPD) or toluene-2,5-diamine, are the most important constituents of these formulations. The aromatic amines swell the cuticle and allows hydrogen peroxide and the dye to penetrate the cortex which removes color and lightens the hair which lasts until the hair grows out. The oxidative dyes are permanent with smallest molecules. The semi-permanent with small molecules containing aromatic amines, cause swelling of shaft, raise the cuticle and allow it to enter the cortex thus coloring it. Three types available are temporary dyes containing large molecules too big to penetrate and only coat the shaft. Earlier natural hair dyes were used but now, due to advancement in cosmetic industry, different types have been developed. For permanent color, the product should penetrate the cuticle to deposit or remove color in the cortex. Shaft has three layers: Cuticle consisting of tightly packed colorless cells, cortex contains natural color pigments that determine color and medulla a hollow core.Ĭoloring agents remove natural color or add new color or accomplish both. Coloring of hair is performed not only by professionals but also a popular cosmetic procedure at home. Hair dye use is very common among both the genders, today millions use it. ![]()
