The intake of linoleic acid (an omega 6 fatty acid) is indispensable to the synthesis of cell membranes. Deficiency provokes the appearance of dry, brittle and thin hair. It also affects the integrity of the skin barrier whereby the skin becomes more sensitive to dehydration and infection.
The omega 6 series of fatty acids are biologically indispensable fatty acids that are derived from an essential fatty acid containing 18 carbon atoms and two chemical double links - known as linoleic acid. Two other long-chain fatty acids are derived from linoleic acid: gamma-linolenic acid (GLA) andarachidonic acid (AA).
Indispensable to the synthesis of prostaglandins (hormonally active molecules) omega 6 fatty acids have a positive effect on the health of the skin and the quality of the hair, as well as the animal’s reproductive system.
Vegetable oils are generally rich in omega 6 fatty acids (eg Borage Oil). Some unsaturated animal fats, from pigs and especially fowl, can also contain large quantities of linoleic acid (more than 20% in the case of fowl). Beef fat (lard, butter) on the other hand contain very little linoleic acid.
