Foods to Promote
Healthy Hair

Nutrient-dense foods keep hair strong, healthy and shiny. Here’s a list of what you need to consume for your crowning glory

Nutrient	Why is it important
Eggs	Eggs provide essential protein and iron, as well as a B vitamin called biotin, which is known to support hair growth. Biotin also strengthens brittle fingernails, so consuming eggs can contribute to overall hair and nail health.
Salmon	Fish such as salmon, sardines, and mackerel are abundant in omega-3 fatty acids, which are essential for healthy hair. These beneficial fats cannot be produced by the body, so they must be obtained from food or supplements.
Lean Poultry	Adequate protein intake is crucial for hair growth. Opt for lean sources of protein like chicken or turkey, as they contain less saturated fat compared to beef . Insufficient protein consumption can lead to hair loss as hair growth is disrupted.
Spinach	Like other dark green leafy vegetables, spinach is packed with nutrients, including vitamin A, iron, beta carotene, folate, and vitamin C. These nutrients work together to maintain a healthy scalp and prevent hair from becoming brittle and breaking.
Sweet Potatoes	If you have dry and dull hair, sweet potatoes can be beneficial. They are loaded with beta carotene, an antioxidant that the body converts into vitamin A. Vitamin A helps prevent dryness and dullness by promoting the production of sebum, an oily fluid that keeps hair moisturized.
Cinnamon	Adding cinnamon to your diet can improve blood flow and circulation, which in turn promotes the delivery of oxygen and nutrients to the hair follicles. Sprinkle cinnamon on your oatmeal, toast, or in your coffee to enjoy its circulation-boosting benefits
Guava	This tropical fruit is rich in vitamin C, which helps protect the hair from breakage. Just one cup of guava contains a high amount of vitamin C, surpassing the minimum daily recommended intake.
