To test hair elasticity, take a small, clean strand of hair and gently stretch it between your fingers. If the hair stretches and returns to its original length without breaking, it has good elasticity. However, if it breaks easily or does not return to its original shape, it indicates low elasticity, often due to damage or dryness. It's best to perform this test on damp hair for more accurate results.
The best time to check the hair's elasticity is when it is wet.
what could happen if hair elasticity was not carried out
test for hair strength, which is done by any service,is carried out. pull a hair between your fingers, does it stretch and spring back if the hair brakes easy the cortex is damaged so chemical processing will cause it to break
it is important to know wheater the bonds are already damaged or not
Hair elasticity testing is carried out to determine the strength and resilience of hair strands. This test helps identify hair damage, such as breakage or brittleness, and helps in deciding on appropriate haircare treatments or products to improve the hair's health and elasticity. It can also provide insights into the overall condition of the hair and its ability to withstand styling and chemical treatments.
Test results, such as porosity and elasticity of the hair, can indicate how the hair will react to the coloring service. This information helps the hairstylist choose the right products and techniques to achieve the desired color without damaging the hair. Test results also help in predicting the longevity and vibrancy of the color.
Your hair consists of hair shafts. A hair shaft is composed of scales that become raised through general daily wear and ear and you will notice your hair becoming dull and lifeless the more these scales are raised. The hair will also lose some of its elasticity, which leads to breakage. The conditioner can help you gain some of that elasticity back.
It depends on the elasticity & overall health of the hair.
Dillon Freasier's Principal, A simple equasion to define elasticity.
The molecular structure of hair, specifically the arrangement of proteins called keratin, determines its strength and elasticity. The more organized and aligned the keratin molecules are, the stronger and more elastic the hair will be. Disruptions in this structure, such as from heat or chemical damage, can weaken the hair and reduce its elasticity.
The elasticity in the hair allows wet hair to be stretched up to 50% of its original length, and you must consider this when you are cutting the hair wet, as the dried results could be much shorter than you or your client anticipated.
The cortex layer of the hair shaft is made of cortical cells. It is the middle layer of the hair shaft and provides strength, elasticity, and color to the hair.
