Linoleic acid is a polyunsaturated fatty acid found in many vegetable oils. It is a member of the omega-6 family of fatty acids. Omega-6 fatty acids are essential for human health, but they must be in the correct ratio with omega-3 fatty acids. Too much omega-6 fatty acids can lead to inflammation.
Although there is no definitive answer to the correct ratio for omega-3 and omega-6 fatty acids, a general guideline is that omega-6 fatty acids should make up no more than 4% of total fatty acid intake, with omega-3 fatty acids making up the remaining 96%.
Linoleic acid is a common ingredient in skincare and haircare products because it is known to help with skin barrier function and hair moisture. It is typically measured in percent by weight.
