The Best 10 Foods For Healthy Hair And Nails
Our hair and nails are dependent on a supply of nutrients from the food we eat to stay strong and healthy. This is not simply a matter of appearance though, as the health of our hair and nails is in fact, a barometer of our internal health.
A poor diet can quickly lead to weak, splitting nails and dull, brittle hair. Shiny hair and strong nails, on the other hand, can be an indicator of good health and nutritional status (1,2).
Hair is a fast-growing tissue and has high nutrient requirements (2).
Important nutrients for healthy hair and nails include protein, zinc, iron, and B vitamins. Omega-3 fats and vitamin A act as natural conditioners.
The fingernails are usually the first place to show visible signs of mineral deficiencies. For example, white spots can be a sign of zinc deficiency and vertical ridges can indicate that you need more iron.
Eating the foods recommended here will not only benefit your nails and hair, but your overall health as well, and are healthy additions to any diet.

Tips for Healthy Hair and Nails
- Exercise - Exercise increases circulation to the scalp and extremities, including the fingers and scalp, which helps deliver nutrients and oxygen to the hair and nails.
- Stress Relief - Stress causes the release of the hormone cortisol from the adrenal glands and reduces circulation, both of which can lead to hair and nail problems over time (24). Try an Indian head massage for stress relief and increased circulation to the scalp.
- Notes on Washing Hair - Washing hair too often can strip it of natural oils leaving it dry, as can harsh products containing chemicals. Wash your hair every 2-3 days and avoid products containing too many synthetic ingredients that may cause allergies or dandruff. Blow-drying too much can also be damaging, so allow hair to dry naturally whenever possible and avoid hair straighteners and curling tongs.
- Notes on Nail Treatments - Avoid harsh nail treatments such as acrylic nails. Instead wear a nail-strengthening product, as bare nails tend to break more easily. Further, use acetone-free nail polish remover.
- Avoid Smoking - Smoking is linked with negative effects on hair health and an increased risk of hair loss (25). Overweight smokers have a six times higher risk of suffering with alopecia (hair loss) than non-smokers of a healthy weight (26).
