Of Ions and Damaged Hair
Hair is void of life right after it leaves the growth area at their tips embedded within the scalp. The pain you get when you tug your hair is from the nerves on the scalp and not the hair. Hair is made of a natural form of plastic similar to the materials your fingernails are made of. Hair under extreme magnification is not smooth as we may think it is, but made up of tiny scales that stems from the roots out adding layer after layer as it grows. the damage we see as breaks and split ends are the result of excessive drying of the hair shaft that causes it to split and even crack, with extreme heat being the most damaging factor, able to melt the hair itself as if it were cooked to perfection.
The many ionic products you see out in the market tends to have ionization characteristics that turns water wetter that it normally is. It breaks the bond between water molecules making them smaller thus more effective at wetting the hair and able to penetrate deeper into the hair shaft. The best hair care repair systems penetrate the hair deeply to allow proper moisture levels to get into the hair, helping it bond together preventing further damage.
