TESTING FOR UNPROCESSED HUMAN HAIR

Testing for a silicon Coating

Human hair is made up of microscopic scales that overlap to form a protective outer layer similar to the scales on fish. You can feel the scales by squeezing a dampened bundle of strands between your thumb and index finger. Moving from top to bottom in the same direction as the scales the hair should feel smooth. Moving upwards from the bottom to the top against the scales and the hair should feel rough with a little friction. You can use the mentioned method with dry hair however you fingers should be moist. The difference is only slight so you may want to repeat the process several times. If you still have difficulty close your eyes so your sense of feeling is heightened, then repeat the process.  

Processed hair has the cuticle stripped back with harsh chemicals to alter the colour and texture (very light blonds can NEVER be achieved using salon products on Asian and Indian hair).  Once the desired texture and colour is achieved a silicon coating is placed over the hair to give a smooth feel. The hair feels smooth when you run you fingers up and down the length of the hair. What you feel is the silicon coating covering the processed hair. Once the coating wears off with brushing and normal wear and tear the hair becomes porous and tangled.

Other tests

Hair that has never had colour treatment will show slight shade variations. As hair grows naturally, the affects of weather and sunlight alter the colour of the older hair towards the ends. It should be noted that using this method is more affective on lighter colours.
