Why Hair Health Starts From Within

Healthy hair is not just about shampoos and conditioners. What you put into your body matters just as much as what you put on it. Your hair follicles require a steady supply of vitamins, minerals and amino acids to produce strong, thick and resilient strands.

If you have noticed increased shedding, thinning, breakage or slow growth, nutritional gaps could be a contributing factor. Hair vitamins and supplements can help bridge those gaps and support your hair from the inside out.

Holland & Barrett Gibraltar stocks a dedicated range of hair vitamins at both stores on Main Street. This guide walks you through the key nutrients for hair health and how to choose the right supplement.

Key Vitamins and Minerals for Hair Growth

Biotin (Vitamin B7) is often called the "hair vitamin." It supports keratin production, the protein that makes up your hair, skin and nails. Biotin deficiency can lead to hair thinning, though this is relatively uncommon. Supplementing with biotin is popular for supporting stronger, thicker hair.

Iron is essential for carrying oxygen to your hair follicles. Iron deficiency is one of the most common nutritional causes of hair loss, particularly in women. If you suspect low iron, a blood test through your GP is recommended before supplementing.

Zinc plays a role in hair tissue growth and repair. It also helps keep the oil glands around hair follicles functioning properly. Low zinc levels have been linked to hair loss.

Vitamin D supports the creation of new hair follicles. Research has linked vitamin D deficiency with alopecia. Given that even Gibraltar's sunny climate does not guarantee adequate levels, supplementation may be beneficial.

Collagen provides amino acids that your body uses to build keratin. It also supports the dermis, the skin layer containing your hair roots. Collagen supplements may improve hair thickness and strength over time.

Vitamin C is a powerful antioxidant that protects hair follicles from free radical damage. It also enhances iron absorption, making it a useful companion to iron supplements.

Omega-3 Fatty Acids nourish hair follicles and support scalp health. They contribute to hair shine and elasticity.

Understanding Hair Loss: Common Causes

Before reaching for supplements, it helps to understand what might be causing your hair concerns. Common causes include nutritional deficiencies (iron, biotin, zinc, vitamin D), hormonal changes such as pregnancy, menopause or thyroid issues, stress and lifestyle factors, over-styling or heat damage, genetics and age-related thinning, and medical conditions such as alopecia areata.

If your hair loss is sudden or severe, consult your GP to rule out underlying conditions.

How to Choose the Right Hair Vitamin

Start by considering your specific concern. For general hair strength and growth, a comprehensive hair, skin and nails formula containing biotin, zinc and vitamin C is a good all-rounder. For hair loss linked to deficiency, target the specific nutrient. Iron and vitamin D are the most common culprits and are best confirmed through blood tests. For ageing or thinning hair, collagen and biotin together can support both hair structure and keratin production. For a holistic approach, combine a targeted supplement with a balanced diet rich in protein, leafy greens, nuts and oily fish.

How Long Before You See Results?

Hair grows approximately 1 to 1.5 centimetres per month. Because of this natural growth cycle, most hair supplements take 3 to 6 months of consistent daily use before you notice visible improvements.

You may see improvements in nail strength and skin quality before hair changes become obvious. Patience and consistency are key.
