Here’s Your Mane Guide to Creating a Healthy Haircare Routine, According to Trichologists

How does diet affect your hair?

Yep, what you eat can take a toll on your tresses.

The biggest culprits, Hallajian noted, are alcohol, refined or added sugars, saturated and trans fats and foods with a high glycemic index—a measurement system that ranks how much certain foods increase blood sugar levels, per Healthline. 

For example, saturated and trans fats, the Âme salon founder said, “can lead to increased levels of Dihydrotestosterone (DHT), a hormone associated with hair loss,” while “high alcohol consumption can lead to dehydration, therefore, hindering the growth of healthy hair.”

On the upside, foods rich in proteins, iron, vitamin C, zinc and B-vitamin “can regulate and stimulate hair growth,” she pointed out, “and reduce shedding and inflammation.”
