According to a study published in the scientific journal Cell Reports, there is a food responsible for hair loss. The research cited was done in mice, and focused on analyzing high-fat diets. The main objective was to discover which fat would be able to cause the growth of cancerous tumors.
In that study, scientists observed and fed three groups of mice diets of fish oil, palm oil, and the third group fed normally.
So, after a while, the mice fed the fish oil diet began to lose hair on their backs. With this observation, the researchers deepened this study in question.
According to them, fish oil can trigger hair loss. However, the issue was not seen in cocoa butter, which is also full of fat.
Hair loss is a natural process that happens to everyone throughout their lives. Normally, we lose around 50 to 100 hairs a day, which is considered normal.
Excessive or abnormal hair loss can be caused by many factors, including genetics, hormones, age, stress, poor diet, illness and medications.
In the research in question, the scientists were able to observe the path of fat through the body of the rodents and noticed that the omega-3, found in fish oil, accumulates in the skin.
Thus, when lodged in the dermis, the oil receives a cytokine response and activates the immune system. In this way, a process of follicular cell death and hair loss begins.
Omega-3s are not often associated with hair loss. This is because there is scientific evidence that proves that omega-3 benefits the hair follicles and scalp, improving blood circulation.
However, the researchers said that generally diets in the US, for example, contain too much omega-3, which may underestimate the adverse effects of the supplement.
“Interestingly, we noticed that nations that rely heavily on fatty fish as a food source (such as Japan) exhibit the most hair loss when compared to other Asian countries," said the researchers.
