Identify Porosity & Density
Take one strand of clean hair and drop in a cup of water. Wait 20-30 seconds and then observe the strand in the water.
Hair Sits On Top- Low Porosity
Hair Floats In Middle- Medium Porosity
Hair Sinks- High Porosity
Stand in front of a mirror. If applicable, shake hair around & allow hair to hang loose. Now attempt to see you scalp through your hair.
Clearly Visible- Low Density
Barely Visible- Medium Density
No Visiblity- High Density
