Your Gut Health Has a Huge Impact on Your Hair Follicles – Here’s What That Means

Everything you need to know.

by | Sep 28, 2021


Having a healthy – and happy – gut isn’t just key to your general wellbeing, it also plays a crucial role in supporting other bodily functions, like your hair.

So to find out more, we spoke to leading Trichologists (an expert in human hair) Lisa Caddy about scalp health, and how it hugely links to internal nutrition.

What is the connection between hair health and your gut?

Gut health may affect our hair either due to dietary related issues or our immune system. Hair requires a balanced amount of macro and micronutrients from the diet to maintain healthy growth and to sustain a normal hair cycle. These macro/micronutrients need to be broken down to enable absorption which occurs in the gut. If the digestive system is out of balance, then nutrients cannot be absorbed.

It is thought our immune systems are significantly affected by our gut. There are several auto immune hair loss conditions, hair loss which is triggered when something changes in our immune system. 

How does this specifically apply to the follicles? 

Hair growth and quality is hugely influenced by our diet. There is substantial evidence that proves nutritional deficiencies such as iron, B12 and zinc to name a few, cause hair loss. It is thought biotin deficiency has an inflammatory effect and has been linked to the overgrowth of other bacteria’s which has a knock-on effect on the hair.

What are the symptoms?

If poor gut health is inhibiting nutrient absorption, then nutritional deficiencies can occur. This can result in seeing an excessive amount of daily hair shedding or feeling that your hair doesn’t grow to a ‘normal’ length.

Digestive issues can lead to inflammation in the body which can trigger inflammatory skin/scalp conditions such as eczema. This is an incredibly itchy scalp condition which causes flaking and discomfort. Inflamed scalps need addressing as this can also lead to hair loss (Philip Kingsley award winning Flaky Itchy scalp range is formulated for all scalp flaking/itching conditions).

Basic blood tests can be undertaken to check for nutritional deficiencies although these are mostly a result of inadequate diet rather than absorption issues. If you eat a very balanced diet and include all the foods groups but discover you have nutritional deficiencies, then it may be an absorption issue connected with gut health. Dairy produce can cause inflammation in some individuals which triggers a scalp flare up so monitor your dairy intake if you are prone to skin/scalp issues. 

What are some ways you can improve your gut and follicle health?

Eating a varied diet and a broad array of foods helps to ensure you have sufficient micro and macronutrients available to the hair follicle. Watch out for inflammatory inducing foods such as dairy, tomatoes, sugar, and mushrooms to name a few. 

To treat flaking and itching scalps including conditions such as eczema and psoriasis, go to the Philip Kingsley Flaky Itchy scalp range. A weekly scalp mask plus daily shampooing with Flaky Itchy Scalp shampoo and application of Flaky Itchy Scalp Toner will alleviate itching and remove flaking, leaving the scalp comfortable and healthy. 

Frequent shampooing (even daily) keeps the scalp environment clean and healthy which promotes optimal hair growth.

8 Of The Best Exercise Shorts That Will Power You Through A Summer Of Movement

It’s official: Shorts Season is officially here. While lockdown has seen many of us realise that activewear is less something to be worn for a workout and more a uniform we choose to do any and all daily activities in, when the warmer temperatures roll around, that favourite pair of sweatpants and leggings sometimes don’t cut it. Sure, they might be a staple in any wardrobe, but the Aussie sun doesn’t listen to reason, no matter how comfortable or cute it might be. And when it comes to summer, working out in leggings can feel like being trapped in a sauna, the sweat pooling at your ankles and around the waistband – as well as those other areas we won’t mention here. 

But as we transition from leggings to shorts, it becomes clear pretty quickly that not all shorts are created equal, and certainly not all shorts are fit for a workout. Take it from us at Women’s Health HQ, we’ve been there, tried it and lived to see the consequences. From the shorts that look cute but ride up to show your undies on the run, to those that feel like being strapped into a harness that’s digging into your hip bones. Then there are the fabrics that can cause chafing – a big no – and those that basically shine a spotlight on any area you might be sweating. 

Thankfully, a number of brands are here to cater to your exercise needs with innovative materials, fabrics and sustainable options to see you through a summer of movement. Regardless of your workout preferences or daily activity, we’ve selected the best shorts that will ensure you feel good in your body, shorts that get you excited to embrace the day and attack it with energy, that make you want to get outside and enjoy the outdoors, whether it be walking, running, or socialising in the park. Here are our pick of the best bike shorts below. 


Uptown Biker, $240

What says summer more than a pop of orange and the sleek shape of these Nagnata biker shorts? With its mid-length and horizontal raised rib side detail, these are shorts you can wear both for a workout and out to meet the girls. Made in Australia with a technical knit fabrication, the double-layer jacquard provides gentle sculpting qualities for the body, making it an excellent choice for light to moderate fitness activities like yoga, pilates or barre.

New Balance

Q Speed Fuel Short, $70

We love the colour of these shorts from New Balance which are cut with a sleek, speedy look that also helps to elongate the legs. Featuring NB DRY moisture wicking fabric, these are the shorts you want for high intensity exercise or long runs, keeping you comfortable and dry. There’s also an interior brief for added comfort and a stash pocket to keep your essentials. 

All Access

Ultra High Rise Zip Front Biker Short, $78

Yes, the colour is amazing but the fit is equally sensational on these All Access shorts. For those who love a high-rise fit and wide waistband that holds you in at the waist, look no further. The sleek, shiny look offers mid-compression and the fabric is moisture-wicking, so you can stay comfortable even during your sweatiest workouts. 


Nike x Naomi Osaka Utility Short, $90

Few things are worse than heading out the door for a run and realising your shorts offer no pockets for those essentials you need. You’re left to hold your iPhone, keys, and anything else you might need in your sweaty palm. Thankfully, Naomi Osaka knows what we need when it comes to exercise shorts and these utility shorts from her collaboration with Nike offer all that and more with a relaxed fit and elastic waistband. 


Session short Tights, $72

When it comes to bike shorts, you want to feel supported and held in but you also want to be able to breathe. These Tracksmith session short tights are exceptional in offering support while still ensuring comfort remains a priority. Forget about chafing, these shorts won’t ride up and down and the fabric offers more coverage and support against the body. 

Outdoor Voices

Relay 3” Short, $48

Who said summer shorts have to be boring? Outdoor Voices brings fashion-forward style and playfulness to their collections with fun prints and exciting colours. We love the relay 3” shorts for their ultralight, quick-drying fabric that also happens to be made from recycled polyester. But more importantly, we love the print and Poppy Swirl is as good as it gets. There’s even a hidden pocket for your valuables, too. 


Align High-Rise Short 6”, $69

If you’re familiar with the buttery-soft feel of Lululemon’s tights, you’ll want to get your hands on a pair of their shorts, too. Made with the same Nulu fabric that their tights are known for, these shorts feel weightless and super soft. They might be our go-to staple for any workout, but the feel is so second-skin that it’s hard to not wear them for every other activity, too. 

Spiritual Gangster

Seamless Biker Short, $112

These biker shorts from Spiritual Gangster move with you, thanks to a three-tiered compressive waistband that offers a flattering high waist that hugs you in all the right places, without proving constrictive. They offer medium compression but are built for all day comfort, and the colour is a true summer staple because, let’s face it, who doesn’t love tie-dye?
