Essential Nutrients for Healthy Hair Growth: What Your Hair Really Needs

When clients visit Hair Again Clinic, one of the first questions they ask is, "What supplements should I be taking for my hair?" While there isn't a single vitamin that can cure hair loss, ensuring your body has the right nutrients is an important part of supporting healthy hair growth and maintaining a healthy scalp.

Hair follicles are among the most active cells in the body and require a constant supply of nutrients to produce strong, healthy hair. Even mild nutritional deficiencies can contribute to increased shedding, slower hair growth and weaker hair.

Iron – One of the Most Common Causes of Hair Loss

Iron deficiency is one of the most common nutritional factors associated with hair shedding, particularly in women. Low iron stores can affect the hair growth cycle, causing more hairs to enter the shedding phase (telogen).

If iron deficiency is suspected, your GP can arrange a blood test to check your ferritin levels. Correcting low iron levels should always be done under medical supervision.

Vitamin D

Vitamin D plays an important role in supporting the normal function of hair follicles. Low vitamin D levels have been associated with several types of hair loss, including telogen effluvium and some forms of alopecia.

Many New Zealanders have low vitamin D levels, particularly during the winter months, making it worthwhile discussing testing with your healthcare provider if you are experiencing ongoing hair loss.

Protein – The Building Block of Hair

Hair is made primarily of a protein called keratin. Without adequate dietary protein, the body may prioritise essential organs over hair growth, resulting in increased shedding or slower regrowth.

Including quality protein sources such as lean meats, fish, eggs, dairy products, legumes and tofu can help support healthy hair production.

Zinc and Biotin

Zinc contributes to normal hair follicle function and tissue repair, while biotin supports normal keratin production. Although true deficiencies are uncommon, they can contribute to poor hair quality and increased hair loss.

It's important to remember that taking excessive amounts of supplements won't necessarily improve hair growth. Supplements should be targeted to your individual needs rather than taken indiscriminately.

Omega-3 Fatty Acids

Healthy fats help support scalp health by maintaining the skin barrier and reducing dryness. Omega-3 fatty acids, found in oily fish, flaxseed and walnuts, may help support a healthy scalp environment.

The Importance of a Personalised Approach

At Hair Again Clinic, we don't believe in a one-size-fits-all approach to hair restoration. During your consultation, we'll discuss your medical history, lifestyle, nutrition and any factors that may be contributing to your hair loss.

Where appropriate, we may recommend professional-grade supplements as part of your personalised treatment plan, alongside advanced regenerative treatments such as PRP, PRF, Growth Factor Concentrate (GFC), Regenera Activa® and other evidence-based therapies.

Healthy Hair Starts From Within

Supplements can play an important supporting role, but they work best when combined with a balanced diet, healthy lifestyle and the right treatment plan for your individual type of hair loss.

If you're concerned about thinning hair or increased shedding, the first step is understanding why it's happening. A comprehensive consultation and scalp assessment can help identify contributing factors and guide you towards the most appropriate treatment options.
