#Mythbusters

A widely held belief suggests that eating fish can lead to faster, thicker hair growth—but what does science really say about this claim? Recent discussion, as highlighted in an article by The Times of India, puts this myth under the microscope and examines whether including fish in the Thai diet directly results in healthier hair.

For generations, the idea that fish promotes hair growth has held strong cultural appeal in Thailand and across Asia, where diets often feature seafood and fresh-water fish. The basis for this belief stems from the nutrient profile of fish, which are rich sources of high-quality protein and omega-3 fatty acids, including EPA and DHA. These nutrients have recognized benefits for overall health, and hair—a protein-based structure—certainly depends on diet for its strength and vitality. According to Harvard Health, deficiencies in key nutrients such as iron, vitamin D, and omega-3s have been linked with hair thinning and loss.

A popular belief holds that eating fish can speed up hair growth and make hair thicker. But what does science actually say? This debate has resurfaced as media outlets question whether fish in a Thai diet directly improves hair health.

In Thailand and much of Asia, seafood is a dietary staple. The nutrition behind this belief lies in fish’s high-quality protein and omega-3 fatty acids, including EPA and DHA. Hair growth relies on protein and overall health, so it makes sense to consider diet. Data from respected health resources show that deficiencies in iron, vitamin D, and omega-3s can contribute to thinning hair.
