“Lather, rinse, repeat” may be standard advice, but shampoo and conditioner alone won’t give you the healthy hair you crave. For the most luxurious locks possible, you’ll need to step out of the shower, and into the kitchen.
Your hair grows about 1/4 to 1/2 inch every month, and the foundation of all of our new hair, skin, and nail growth is the nutrients we eat. If you eat a healthy diet, you will grow stronger and healthier cells throughout your entire body — inside and out.
If you were born with fine, thin hair, you’ll never have rope-thick tresses — no matter what you eat — but a well-balanced diet that includes plenty of growth-promoting protein and iron can make a difference, say nutrition and hair experts. And beware of dietary supplements often marketed to thicken hair or make it grow faster. They may backfire. In rare instances, excess supplementation of certain nutrients, such as vitamin A, has been linked to hair loss.
