We often focus on shampoos, treatments and hair products when it comes to maintaining healthy hair. But beautiful, strong hair also depends on what we nourish our bodies with.
Certain nutrients play an important role in supporting healthy hair growth, strength and scalp health. This post takes a look at some of the key nutrients that you should include in your daily diet.
Protein:
Hair is mainly made of keratin, a type of protein. Not getting enough protein may cause hair to become dry, weak and prone to breakage and can interfere with normal hair growth.
Biotin:
Biotin (Vitamin B7) is a water-soluble vitamin that helps support energy and amino acid metabolism and is closely linked to hair health.
Zinc:
Zinc plays an important role in protein production, cell activity, wound healing and immune function. Inadequate zinc intake may be associated with dry, flaky scalp and hair loss.
Iron:
Iron is essential for red blood cells to transport oxygen and nutrients. Low iron stores may disrupt the normal hair growth cycle, potentially leading to unhealthy hair and hair loss.
Plant-based iron is less readily absorbed by the body. If you follow a vegetarian diet, eating vitamin C-rich fruits and vegetables alongside iron-rich foods can help improve iron absorption.
