Women want hair that is beautiful, healthy, shiny, strong, full and manageable; however, most women face frequent frustration with their locks (or lack thereof).
In fact, only one in ten women has a “great hair day” every day, and more than 40% are either “extremely” or “very” concerned about their hair health. They constantly search for new products and other ways to achieve optimal hair health—including making changes in their lifestyle or what they eat.
In the lifestyle category, there is much academic interest in the role that stress, exercise and sleep play in our skin, hair and health in general. The links between skin and overall health are well-documented, but connections to hair health are less clear.
The academic literature tends to cover the detrimental role of lifestyle factors such as high UV exposure and smoking on hair rather than the impact of nutrition on hair. In the diet category, there is also no definitive answer as to whether what we eat has any impact on hair health.
