Why do chemical hair Texturizers temporarily raise the pH of the hair?
Chemical texturizers raise the pH of the hair to an alkaline state in order to soften and swell the hair shaft. This action opens the cuticle layer and allows the solution to reach the cortex layer, where restructuring takes place.
What is the process of chemically altering the natural wave pattern of the hair?
Chemical hair relaxing is the process or service that rearranges the structure of curly hair into a straighter or smoother form.
What is the Croquignole method of wrapping?
What is the croquignole method? What is the spiral perm wrap? The hair is wrapped at an angle other than perpendicular to the legnth of the rod, which causes the hair to spiral, like the stripes on a candy cane. The diameter remains constant.
What type of hair requires a highly alkaline chemical solution?
Chemical Texture/ haircoloring
| Question | Answer |
|---|---|
| Which type of hair requires a highly alkaline chemical solution? | coarse, resistant hair |
| The most common type of perm rod is the: | concave rod |
| The sulfites used as low-pH relaxers are compatible with: | thio relaxers |
What is used to protect the skin and scalp during hair relaxing?
Coating your scalp with a base of petroleum jelly before applying the relaxer can help protect the scalp from chemical burns. Avoid coloring and relaxing your hair at the same time.
What is chemical waving?
Permanent hair waving is a chemical/mechanical treatment aimed at modifying hair protein to achieve and retain curly shapes. The hair fiber is weakened and can now conform to its new shape. The oxidation step then chemically locks the new molecular confirmation of the hair proteins.
What is the name of the product used to reduce the curl pattern?
What is the name of the product used to reduce the curl pattern? The curl rearranger is the product used to reduce or relax the natural curl pattern.
What is the pH of an alkaline perm?
Alkaline perm has a pH balance of between 8.2 and 9.6 while Acid perm has a pH balance of between 4.5 and 6.5. 5. Alkaline perm is stronger and is good for coarse and thick hair while Acid perm is gentler and good for damaged hair.
What do chemical Texturizers do to the pH of the hair?
hair services that cause a chemical change that permanently alters the natural wave pattern of the hair. Chemical texturizers raise the pH of the hair to an…. bonds that cross-link the polypeptide chains together and are responsible for the extreme strength and elasticity of human hair.
What type wrapping rodding technique is the hair wound from the hair ends toward the scalp?
Croquignole
Croquignole: hair is wound from ends to scalp in overlapping layers. ii. Spiral: two methods—from ends to scalp/scalp to ends; requires vertical rod positioning while wrapping.
What foods have a pH above 7?
Foods with an alkaline ash have pH values above 7. Foods with an acid ash have pH values below 7. Pure water has a neutral pH of 7. In general most grains, dairy products, meats, seeds, legumes and nuts tend to have an acid ash.
What is 7 on the pH scale?
The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value.
What is the pH scale and how does it work?
It is a scale used to measure the acidity or alkalinity of a solution. The pH scale uses a range from 0 to 14, with 7.0 indicating neutrality. Numbers beginning at 7.0 and moving toward 0 indicate acidity, while the numbers beginning at 7.0 and moving toward 14 indicate alkalinity, so the scale divides acids from bases.
Which has a pH over 7?
Substances over 7 are categorized as basic, with 7 being the neutral point. Water has a pH level of 7. Substances with pH levels under 7 are categorized as acidic. Vinegar is acidic. Vinegar’s pH level varies based upon the type of vinegar it is. White distilled vinegar, the kind best suited for household cleaning, typically has a pH of around 2.5.
