Some cosmetics manufacturers claim to make hair products that contain keratin to strengthen hair or promote hair growth. However, the cells in hair follicles make all the keratin protein that they require from amino acids supplied via the blood.
Other fibers on the market are made from dyed wool which is an animal by product, hence their claim to "keratin fibers". This is also the reason so many people have itching on their scalp. So how does Claiming that Keratin is in competitors Hair Building Fibers present any purpose, value, or benefit?Hairtek hair fibers is proud to say that there were no animals used in our products nor our hair styling products testing.
What is Keratin?
The primary component of human hair fiber is keratin. Keratins are proteins, long chains (polymers) of amino acids. Keratin proteins form the cytoskeleton (miniature skeleton within a cell) of all epidermal cells. Keratin filaments run within a cell from the inside of the outer membrane to weave a "basket" around the nucleus of the cell. Keratins are a principle part of the cells in the epidermis, hair, nails, feathers, hooves, tissues and the enamel of teeth.
Keratin found in human hair
In hair fiber, keratin proteins comprise 65-95% of the total hair fiber by weight. Each molecule of keratin is very small - about 10 nanometers across. To give you a sense of how small that is, 10,000 keratin molecules lined up side by side would cover the width of the average terminal scalp hair.
Some cosmetics manufacturers claim to make hair products that contain keratin to strengthen hair or promote hair growth. However, the cells in hair follicles make all the keratin protein that they require from amino acids supplied via the blood. So how do competitor’s products claiming to have Keratin in their Hair Building Fibers present any logical purpose, value, or benefit? In our opinion, it does not. In fact, keratin is used as a marketing buzz word and by adding some wool fibers to the product is how they claim they are selling natural Keratin hair fibers. Do not be fooled by disingenuous advertising. Know the facts.
