You're not eating a diet that's good for your hair.
If your strands are looking brittle and lifeless, what you are eating could be to blame. Skjoth shared that intensive low-fat diets can cause these problems with your hair.
"Forget about all the low-fat food and seek out full, healthy fats instead," he said. "Your hair, your skin, and, for that matter, your overall health will thank you." He recommends fatty, wild-caught fish like mackerel, herring, sardines, and salmon; avocados, seeds, and nuts; cold-pressed extra virgin olive oil; and plenty of dark greens.
"These fats heal and are great for your hair, so make room in your diet for those foods in particular," he noted. He also advised bumping up the protein in your regular meals. Protein is a building block of keratin, which makes hair strong and healthy. Skjoth particularly likes recommending grass-fed red meat, milk products (including butter and Greek yogurt), eggs, and poultry, which are nutrient-dense from the grass.
If you cut back on sugar and simple carbs like white rice, pasta, and bread, you'll see an even bigger difference in your hair. "They are devoid of essential nutrients your hair (and the rest of your body) needs in order to remain vibrant and strong," Skjoth explained. "The lack of high-quality micronutrients, lack of trace elements and certain vitamins, the high percentage of processed carbohydrates, and lack of fibers are detrimental to healthy hair growth."
Finally, reconsider what kind of water you drink. Spring water imported from Europe (in particular, France, Italy, and Iceland) is loaded with unprocessed, essential trace minerals like iron, calcium, magnesium, and sulfate, which can improve overall body function. Look for brands like Evian, Volvic, Acqua Panna, San Pellegrino, and Icelandic Glacial.
