Healthy hair starts with more than shampoo and conditioner. Your body needs adequate nutrients to support normal hair growth, maintain hair structure, and replace strands that naturally shed.
While no single food guarantees thicker hair, a balanced diet provides the building blocks your body needs.
Five nutrients worth knowing
1. Protein
Hair is primarily made of a protein called keratin. Insufficient protein intake can contribute to noticeable hair loss.
Good sources include eggs, fish, chicken, beans, milk, and yoghurt.
2. Iron
Iron helps your body produce haemoglobin, which carries oxygen in the blood. Inadequate iron levels can contribute to hair loss.
Include foods such as lean meat, beans, lentils, and dark leafy vegetables. Pair plant-based iron sources with vitamin C-rich foods to improve absorption.
3. Zinc
Zinc supports normal tissue growth and repair. Sources include seafood, meat, eggs, beans, nuts, and seeds.
4. Vitamin D
Vitamin D plays several roles in the body, including supporting bone and immune health. Low levels have also been associated with certain hair loss conditions.
5. Biotin
Biotin is a B vitamin involved in energy metabolism. Deficiency can affect hair, skin, and nails, although it is relatively uncommon.
Food before supplements
You can obtain many important nutrients from everyday foods. Eggs, beans, fish, vegetables, fruits, nuts, and whole grains can all contribute to a nutritious diet.
The goal is not to consume excessive amounts of individual vitamins. Too much of certain nutrients can cause harm and may even worsen hair loss.
Remember that hair growth takes time
Improving your diet will not produce overnight results. Hair grows gradually, and correcting a nutritional deficiency does not guarantee that every form of hair loss will resolve.
If you are experiencing unusual shedding or thinning, seek professional advice before starting supplements.
Good nutrition supports healthy hair, but it also supports your entire body. That makes a balanced diet worthwhile, whether or not you notice changes in your hair.
