Sun (UV) Protection
Solar Simulator
If you want to show how well your products protects the hair from UV or sun damage, then you may consider performing a UV protection study.
Our UV protection studies artificially expose hair to high levels of simulated sunlight.  The intensity of the light is equivalent to continuous unbroken sunshine at mid-day, in a country close to the equator.  We have shown that this is roughly 4.5 times the sun exposure you would actually get over a full 24 h in Florida or Nevada.  The effects of UV damage can be measured using tensile testing, differential scanning calorimetry (DSC) and dry combing testing techniques.   It has been shown that UV sunscreens, if applied correctly, can provide some protection to hair against sun damage.
