Semipermanent dyes are longer-lasting than tem- porary dyes since they are retained in the hair shaft by weak polar and van der Waals attractive forces discount fincar 5 mg fast delivery. Usually order fincar 5mg free shipping, 10 to 12 dyes are mixed to obtain the desired shade, which must be darker than the natural hair color (52). Thus, in the cosmetic industry, semipermanent dyes are known as suitable for staying on shade. Semipermanent hair colorings derived from textile dyes are popular with both men and women. Since human hair is basically a textile, dyes for wool and natural ber cloths are well suited for adaptation to hair dyeing. Sometimes these dyes are combined with henna, botanically known as Lawsonia alba, to create a natural vegetable dye. However, most of the currently marketed vegetable dyes use a small amount of synthetic henna, com- bined with traditional semipermanent dyes, to achieve the desired hair color. These dyes are commonly available as shampoos and mousses that are applied to wet, freshly shampooed hair and rinsed in 20 to 40 minutes. A newer, longer-lasting form of the semipermanent dye, known as a demipermanent hair coloring, usually lasts through 10 12 shampooings. This is due to enhanced dye penetration into the hair shafts facilitated by the addition of small amounts of ammonia. As might be expected, demipermanent dyes are more damaging to the hair shafts than semipermanent dyes. Permanent Dyes Permanent hair coloring is the most popular hair-coloring technique used by men and women due the tremendous color variety available. Permanent hair coloring can dye hair both lighter and darker, achieving almost any color desired by the user. The hair color is permanent because the dyestuff penetrates the hair shaft to the cortex and forms large color molecules that cannot be removed by shampooing (54). This type of hair coloring does not contain dyes, but rather colorless dye precursors that chemically react with hydrogen peroxide inside the hair shaft to produce colored molecules (55). The process entails the use of primary intermediates (p-phen- ylenediames, p-toluenediamine, p-aminophenols), which undergo oxidation with hydrogen peroxide. These reactive intermediates are then exposed to couplers (resorcinol, 1-naphthol, m-aminophenol, etc. These indo dyes can produce shades from blonde to brown to black with highlights of gold to red to orange. Variations in the concentration of hydrogen peroxide and the chemicals selected for the primary intermediates and couplers produce this color selection (56). The form of permanent hair dyeing that leads to hair-color lightening is known as bleach- ing. In one-step processing, the dyeing and lightening procedures are per- formed as one step, but the hair cannot be dramatically lightened. One-step processing uses the same dyes as discussed previously, except the hydrogen peroxide used in the oxidation dyeing process is used to lighten the existing hair color, a phenomenon known as lift. This technique is used when patients wish to dye their hair much lighter than their natural color or if the hair contains more than 60% gray. Removing of the natural hair Nonmedicated Grooming Products and Beauty Treatments 67 pigments, a process known as hair bleaching, is achieved with an alkaline mixture of hydrogen peroxide and ammonia. This causes swelling of the hair shaft allowing easier penetration of the dye, known as a toner (57). The toner must be used since hair completely stripped of color has an undesirable grayish appearance. Specically, permanent hair curling is used to make straight hair wavy, curly, or kinky. The chemistry of the permanent wav- ing process is based on the 16% cystine incorporated into disulde linkages between polypeptide chains in the hair keratin lament. These disulde linkages are responsible for hair elasticity and can be reformed to change the conguration of the hair shaft. Permanent waving utilizes three processes: chemical softening, rearranging, and xing of the disulde bonds (58). The basic chem- istry involves the reduction of the disulde hair shaft bonds with mercaptans (59,60). The standard permanent waving procedure involves initial shampooing of the hair to remove dirt and sebum. This wetting process with water is the rst step in preparing the hair for chemical treatment, since the water enters the hair s hydrogen bonds and allows increased exibility. The hair is then sectioned into 30 to 50 areas, depending on the length and thickness of the hair, and wound on mandrels or rods with holes to allow the permanent waving solution to contact all surfaces of the hair shaft. The size of the rod determines the diameter of the curl with smaller rods producing tighter curls and larger rods producing looser curls.

Mortality time trends from selected causes in Europe (standardized rates per 100 buy discount fincar 5 mg online,000 population) discount fincar 5 mg otc. In Greece there was plateau oscillating at the level of 100/100,000 for the whole period of observation. The pace of that decline is similar or even faster than the one observed in Western Europe. In men decline was observed in all countries around 1990s, it was slightly delayed in Hungary and began favorably earlier in Slovenia. In women generally there was a plateau observed until mid 1980s and then the decline was observed. Generally comparing the year 1990 with 2002 we observe decline in all countries except in Bulgaria in both genders, and Romania in men only (what contrasts with situation development in Russia). On the contrary, most data on hospital discharges are not validated, therefore they are not completely reliable; moreover hospital admission policies vary over time and space. Innovations in diagnostic technologies have facilitated diagnosis at earlier phases in the course of the natural history of disease or in presence of less severe tissue damage. All these factors may have an influence in producing spurious trends of disease frequency, severity, prognosis and variations in medical practice, leading to wrong conclusions and decisions if not properly controlled with the adoption of updated and valid epidemiological methods [35]. The declining trends of mortality during the late 1970s and 1980s suggest that acute stroke events have become milder and that the prevalence of stroke survivors is increasing. This decline is only partly attributed to an improvement in the control of hypertension. There is evidence suggesting that a decrease in the prevalence of some environmental factors (dietary salt intake and saturated fat) has contributed more than pharmacological treatment [20]. Falling mortality rates have resulted in longer life spans; however, it is recognized that trends do not change equally across countries. For this reason, it is important to monitor disease trends, treatments and risk factors in order to improve public health through planning and implementing preventive actions in the different countries. Innovations in medical, invasive and biological treatments contribute substantially to the escalating costs of health services and it is therefore urgent to have reliable information on the magnitude and distribution of the problem both for adequate health planning and clinical decision making with correct cost-benefit assessments. Anyway, it should be noted that these policies, although important, would target only 20-30% of adult population. On the contrary, strategies to encourage people to adopt healthy diet and make physical activity are usually addressed to the overall population. In particular, it is advisable to encourage healthy lifestyle since childhood and throughout the life span in order to assure adulthood with favourable risk profile and without need of pharmacological treatment (primordial prevention). After five years, significant improvements were documented in smoking, cholesterol and blood pressure. The program was so successful that it was expanded to include other lifestyle-related disease. Low risk individuals live longer and are eligible for low medical care expenditures in the last years of life [39]. Across Europe with its ageing population there is a pressing need to cope with costs increase and make prevention and treatment a priority to reduce the growing health burden and lessen its socio-economic impact [40].
