This makes up the primary composition of hair.
What is keratin?
These bonds found within the hair help organize protein chains in order to build hair.
What are side bonds?
These have a negative charge.
What are electrons?
This is the most abundant element on earth and the second-most abundant element in the earth's atmosphere?
What is oxygen?
On the pH scale this is indicated by a number less than 7.
What is acidic solution?
This is cleaning the scalp and hair and removing all foreign matter without adversly affecting either the hair or scalp.
What is shampooing?
These bonds can be easily broken with heat or water.
What are hydrogen bonds?
The three main parts of an atom.
What are protons, neutrons, and electrons?
This contains certain salts of calcium, magnesium, and other metals that prevent shampoo from lathering.
What is hard water?
This is when a solution has an equal number of hydroxide and hydrogen atoms.
What is neutral?
This is how far healthy hair can be stretched without breaking when wet.
What is 50%?
This is a combination of secretions from the sebaceous glands and perspirations from the sweat glands.
What is the acid mantle?
This is two or more of the same atom joined together by a chemical bond.
What is a molecule?
A substance that can disolve another substance is this.
What is a solvent?
A pH of 5 is this many more times acidic than a pH of 6.
What is 10?
This is one of the gases that makes up hair with hydrogen and nitrogen.
What is oxygen?
These are created when amino acids join together in chains.
What are proteins?
This is represented by the atomic number in a particular element.
What are the number of protons?
This is purifying water by passing it through a porous substance.
What is filtration?
This is the pH range of healthy hair and skin.
What is 4.5 to 5.5?
This is when protein chains bond to other protein chains.
How is human hair formed?
This bond is the backbone of all protein molecules.
What is the peptide bond?
This has the simplest atomic structure.
What is hydrogen?
This is when two hydrogen atoms combine with one oxygen atom and the result is a water molecule.
What is a compound?
This shampoo has a pH of 4.5 to 5.5 on the pH scale.
What is pH balanced shampoo?
