The Best Foods for Healthy Hair – Especially During Weight Loss
How to protect your hair while slimming down — and the truth about food, hormones & support in Neath
Hair is often seen as a symbol of health and vitality. But what many people don’t realise is that your hair also reflects your inner wellbeing — particularly your nutrition. If you’re trying to lose weight or using a weight-loss medication such as Mounjaro® (tirzepatide), you might notice thinning, shedding or dryness. It’s more common than you think — and with the right approach, it’s usually temporary and reversible.
At The Health Dispensary in Neath, we take a whole-health approach to weight management. In this article, we’ll explore:
- The best foods for hair growth and scalp health
- How nutrition and hormones affect your hair during weight loss
- The role of supplements like collagen and Pycnogenol®
- How our pharmacist-led team supports healthy, sustainable weight loss with Mounjaro® prescribing and nutritional advice
🥦 Why Nutrition Is the Key to Hair Health
Hair is made mostly of keratin, a protein built from amino acids. For healthy growth, your body needs a constant supply of protein, vitamins, minerals and essential fats. During calorie restriction or rapid weight loss, the body prioritises vital organs over hair growth, leading to shedding or dullness. If you’re using Mounjaro®, its appetite-suppressing effect can make balanced nutrition trickier—so choosing nutrient-dense foods is essential.
🥚 Top Nutrients and Foods That Feed Your Hair
Here are the key nutrients your hair needs and where to find them.
1. Protein – The Foundation of Hair
Why it matters: Hair is built from protein. Without enough, it becomes weak and brittle.
Sources: Eggs, Greek yoghurt, chicken, tofu, lentils and quinoa.
Tip: Start your day with eggs on toast or yoghurt with berries.
2. Iron – For Strong Roots and Growth
Why it matters: Iron carries oxygen to hair follicles. Low iron is a leading cause of hair loss.
Sources: Spinach, kale, lean red meat, lentils, pumpkin seeds.
Tip: Pair with vitamin C foods for better absorption.
3. Omega-3 Fatty Acids – For Shine and Scalp Health
Found in salmon, mackerel, walnuts, flax and chia seeds; they calm inflammation and nourish follicles.
4. Zinc – For Repair and Resilience
Zinc maintains healthy oil glands and scalp tissue. Good sources include oats, pumpkin seeds, chickpeas and whole grains.
5. Biotin – The “Hair Growth” Vitamin
Supports keratin production. Found in eggs, almonds and sweet potatoes. Most people get enough from food.
6. Vitamin A – For Scalp Moisture
Needed for sebum production. Sources: carrots, kale, spinach, sweet potatoes. Avoid excess supplementation.
7. Vitamin E – For Circulation and Shine
Boosts scalp blood flow. Sources: avocados, sunflower seeds, spinach.
8. Collagen – For Strength and Elasticity
Collagen supports skin and hair structure. Found in bone broth, chicken skin and egg whites, or as a supplement. We stock high-quality collagen supplements in Neath and online across the UK — ideal if you’re over 30, losing weight or under stress.

🌲 Pycnogenol® – The Pine Bark Powerhouse for Hair and Skin
Pycnogenol® is a natural extract from the French maritime pine tree. Its antioxidant and circulation-boosting effects support both scalp and skin health.
- Improves microcirculation to hair follicles
- Supports collagen and elastin
- Reduces oxidative stress linked to hair thinning
A 2015 study found women taking Pycnogenol® for two months showed a significant increase in hair density.
