The hair products most suitable are those with antioxidants such as lycopene, flavonoids, riboflavin and vitamin C, and those containing thalitan, Containing magnesium and manganese.

So the hair, especially longer and tend to be dry, they lose brightness and are more likely to florescence (file split ends).
Outer cuticle: consists of unpigmented cells arranged like shingles on a roof, which function of protection.
Bark: consists of pigment cells rich in melanin, which are linked together to form filaments of alpha keratin.
Microfibrils: protofibrils formed by connected to each other by a matrix of high sulfur content.
Protofibrils: formed by three helical keratin fibers.
Life cycle of hair
The life of hair has three phases:
Anagen (2-7 years): hair growing, with the formation of new cells. In humans lasts from 2 to 4 years and in women from 2 to 7 years. The hair grows one centimeter per month.
Catagen (7-15 days): in the matrix, the decrease mitosis and disappear. The bulb appears on the surface and prepares for the next stage.
Telogen (5-6) weeks: is the resting phase. The hair can remain subject, but after a certain period falls loss of grip and by the thrust of new hair.
