Concentration Limits

The aim of this work was to optimize our natural hair dyeing system which we described in our previous work and to compare with other dyeing systems. Therefore, we investigated concentration limits of matcha and mordant and compared this new dyeing method with commercial permanent systems on the market. Completely unpigmented hair tresses were dyed with matcha powder (camelia sinensis) and iron(II)-lactate. To investigate the wash fastness and concentration limits, the differently dyed hair tresses were spectrophotometrically measured. The comparison of the damage potential for which cysteic acid is an indicator was measured by NIR. The concentration of matcha and mordant are responsible for the intensity of the color results. The higher the matcha or the mordant concentration, the darker the color results of the dyed hair tresses. Hair damage of matcha mordant dyeing is comparable with results of commercial permanent hair coloration systems. Moreover, the results of wash fastness of matcha mordant dyed hair tresses is comparable and even better by tendency to permanent colored hair tresses.

Mordant Dyeing

When pre-chromed wool is immersed in a boiling solution of a mordant dye, the dye is rapidly absorbed by the wool. This is followed by a slower reaction in which the dye reacts with the chromium(111) in the wool to form either a 1 : 1 or a 1 : 2 chromium(111)-dye complex. With solo-chrome violet RS only a 1 : 2 complex could be detected in agreement with the results of earlier workers, but with solo-chromate fast red both 1 : 1 and 1 : 2 complexes were detected in the wool. The equilibrium [Cr(dye)L(H2O)2] + dye ←→ [Cr(dye)2] + L + 2H2O lies further to the right when L is a negatively charged ligand such as SO42- or F- than when L is a neutral ligand such as H2O. This accounts for the preferential formation of 1 : 2 complexes in wool, where L is a carboxylate ion. It is shown that on average 1 : 1 chromium(111)-dye complexes are bound to slightly more than one carboxyl group. An explanation is advanced for the higher wash-fastness of the 1 : 1 and 1 : 2 chromium(111)-dye complexes relative to the corresponding free dyes.

Mordant Dyeing

Schizandra is a mature fruit of Fructus Schisandrae Chinensis. The wool fabric was dyed with a natural schizandra dye. The adsorption kinetics and thermodynamics of using mordant and direct dyeing technology were studied. The influence of dyeing time and temperature on wool fabric were explored. The research result shows that the adsorption kinetics of schizandra dye on wool fabric meet the pseudo second-order kinetic model and the rate constant k2indicated a faster adsorption rate of mordant dyeing than for direct dyeing. The negative value ofΔGvalidated the feasibility of the sorption process, and the sorption of schizandra dye on wool fabric is spontaneity, whichever the dyeing method is direct dyeing or mordant dyeing.

95% of hair loss in men is caused by Androgenetic Alopecia. Major causes of hair loss are Stress, Pollution, Lack of nutrition, Illness, Alcohol, Smoking, Effluvium. For hair loss should we take oral drugs or apply topically on hair? It’s a big question for all of us. Before discussion we need to know the Hair Constituents: Human hair consists of approximately 65 % to 95 %protein. Besides cystine, human hair cuticle contains cysteic acid, proline, thereonine, isoleucine, methionine, leucine, tyrosine, phenylalanine in quite high proportion. The remaining constituents are water, lipid, pigment & trace elements that are not free but bound with protein or fatty acids side chain. So…? Consumed food products should contain; PROTEIN, LIPID, WATER and TRACE ELEMENTS. For direct impact on structure, growth and keeping hair shiny and healthy. Standard value proteins containing Sulphur amino acids: Cysteine & Methionine as precursor to keratin hair protein Synthesis are basic element of diet conditioning of hair building.

Mordant Dyeing

Purple sweet potatoes were applied to extract anthocyanins for dyeing silk fabrics. Dyeing and anti-ultraviolet properties of anthocyanins were investigated. The color yield, exhaustion behaviors, fastness properties and anti-ultraviolet properties of dyed silk fabrics were also discussed. The results showed that high color strength value (K/S value = 3.01) was achieved at 50 °C and pH 3. The washing and rubbing fastness properties were enhanced by mordant dyeing method using alum. The dyed silk samples displayed good anti-ultraviolet and the UV transmittance was decreased by 46% at 300nm and 58% at 360nm.

Using standard techniques of scanning electron microscopy (SEM), over 1000 human hair defects have been studied. In several of the defects, the pathogenesis of the abnormality has been clarified using these techniques. It is the purpose of this paper to present several distinct morphologic abnormalities of hair and to discuss their pathogenesis as elucidated through techniques of scanning electron microscopy.

Ruthenium red has been used as a stain to demonstrate a variety of extracellular materials, especially acid mucopolysaccharides. It also reacts with certain intracellular and extracellular lipids. Since biochemical studies in our laboratory demonstrated the presence of a variety of monosaccharides in human hair ruthenium red staining procedures were adopted in order to evaluate the presence and morphological location of acid oligosaccharides in the keratinized aspect of hair.

The purpose of this study was to examine the external structure of four human hair shaft samples with the scanning Electron Microscope (SEM) and to obtain information regarding the chemical composition of hair by using the attached x ray microanalysis unit.The hair samples were obtained from two female subjects. Sample A was taken from a black female and had not undergone any type of chemical processing. Sample B, C, D were taken from a white female, and were natural, processed, and unpigmented, i.e. “gray”, respectively. Sample C had been bleached, tinted, and chemically altered using a permanent wave technique.

Sem Study

High school cosmetology students study the methods and effects of various human hair treatments, including permanents, straightening, conditioning, coloring and cutting. Although they are provided with textbook examples of overtreatment and numerous hair disorders and diseases, a view of an individual hair at the high resolution offered by an SEM provides convincing evidence of the hair‘s altered structure. Magnifications up to 2000X provide dramatic differences in perspective. A good quality classroom optical microscope can be very informative at lower resolutions.Students in a cosmetology class are initially split into two groups. One group is taught basic controls on the SEM (focus, magnification, brightness, contrast, specimen X, Y, and Z axis movements). A healthy, untreated piece of hair is initially examined on the SEM The second group cements a piece of their own hair on a stub. The samples are dryed quickly using heat or vacuum while the groups trade places and activities.
