The Science to Good Hair

We all have good hair days and bad hair days - perhaps it’s caused by the weather, being overdue for a wash, or simply waking up on the wrong side of the bed! However, did you know that when it comes to the overall health of your hair, there’s a science behind it? This means that you can actually stack the odds in your favour so the good hair days are the norm. Here are 5 research-backed lifestyle factors for long, strong, lush locks...

Don’t Lose Hair Over It!

Hair loss is often reported clinically during periods of excessive stress and elevated stress hormones. This is why implementing stress management techniques can support your overall hair health - not to mention your total state of wellbeing! Ensure you are taking time for yourself whether that be doing a yoga flow, having a relaxing bath, going for a walk or getting an early night! Deep belly breathing and meditation are also fantastic ways to quickly relieve stress if you find yourself in a moment of anxiety or overwhelm.

Eat for Hair Health

The secret to good hair partly lies on your plate! When it comes to your diet, focus on eating adequate quality protein and iron for optimal hair strength and growth, as a nutritional deficiency may impact both adversely. Plus, protein malnutrition can result in hair changes that include hair thinning and hair loss… no thank you!

Whether you are a meat-eater, pescatarian, vegetarian or vegan, there are plenty of delicious and nourishing foods you can get all your amino acids from! Ensure you're including protein from sources such as lean meats (organic and grass-fed when possible), fish (salmon, mackerel or sardines are rich in omega-3 fatty acids), eggs, legumes (lentils, beans, chickpeas), tempeh/tofu, nuts, seeds and dark green leafy vegetables (spinach, broccoli, Brussels and kale). 


Frequently drying your hair with a hair dryer? This can cause damage to the hair, including roughness and dryness. Natural drying of the hair, such as gently removing dripping water with a towel and then letting it air dry is considered safer than using a hair dryer. If you do use a hair dryer, finish by blasting the hair with the cool setting, to help seal up the hair cuticles which become open and exposed at higher temperatures, contributing to dryness and making hair more prone to breakage.

What the Friction?

Other hair styling related causes of damage to the hair shaft include friction from hair accessories, washing and vigorous towel drying. Friction especially is a main damage factor in wet hair! Be gentle and opt for hair accessories made from soft fabrics, such as silk scrunchies, to minimise damage.


Exposure to UV impairs hair fibers and sunlight can play a role in hair aging and result in dryness, rough surface texture and increased stiffness and brittleness. In light-induced ageing, the hair becomes pale and the changes that impair the softness and shine occur on the surface. It’s important that hair fibres are protected from light, so make sure to sit in the shade and wear a hat when you’re out in the sunshine!
