Hair Structure
The outermost layer of the hair. It protects the cortex from damage and moisture loss. Formed of colorless, translucent scales. Has the ability to expand and contract as it takes or releases water.đź’¦
What is the CUTICLE?
65-95% of the hair structure. This gives hair the ability to contract.
Specialized cells that create all melanin found in the hair, skin, and eyes.
What are MELANOCYTES?
A molecule with an electrical charge.
What is an ION?
Hydrogen, Salt, and Disulfide are examples of what found in the hair?
What are SIDE BONDS?
The innermost portion of the hair shaft. Comprised of soft keratin protein and air spaces. It does not have a specific function, size, or shape.
What is the MEDULLA?
Up to 32% of hair composition. Gives the hair the ability to stretch.
What is MOISTURE?
This type of melanin is characterized by looking black/ brown in color. Levels 1-5. Oxidation turns it red. Contains more iron.
What is EUMELANIN?
The ion with a positive charge and is acidic.
What is a HYDROGEN ION?
The amount each bond makes up of the hair’s overall strength.
What is 1/3?
The strongest part of the hair. It represents 85% of the total weight. It is made of twisting fibers of keratin protein. This is where melanin resides.
What is the CORTEX?
This component acts as a “glue” holding the protein together.
What is a LIPID?
This type of melanin is characterized by a reddish orange color. Levels 6 and higher. It contains copper, and oxidation turns orange.
What is PHEOMELANIN?
The ion with a negative charge and is alkaline.
What is a HYDROXIDE ION?
The bond easily affected by water and heat.
What is a HYDROGEN BOND?
This hair texture has as many as 18 layers of cuticle.
What is COARSE hair?
This component is responsible for the hair’s “shine”.
What is MINERALS?
The color hair turns when production of melanin completely stops.
What is WHITE?
This means “strength of hydrogen” and is abbreviated as pH.
What is PROTENZ HYDROGEN?
The bond that is fairly weak and is affected by changes in pH.
What is a SALT BOND?
To be “water loving”.
What is HYDROPHILIC?
This component is responsible for flexibility to the hair.
What is a CARBOHYDRATE?
What helps promote the production of melanin and without adequate amounts of it in the body, will result in the hair loosing color or turning gray?
What are AMINO ACIDS?
pH can only be measured when this is present.
What is WATER?
The bond that is the fewest in number but the strongest. It is affected by reactive chemicals.
What is a DISULFIDE BOND?
