If you’ve noticed more hair in your brush, drier ends or a change in texture as autumn rolls in – you’re not imagining it. Just like our skin, our hair responds to seasonal shifts in temperature, humidity and environment.
At Hair + Me, we know that understanding why your hair behaves differently during seasonal transitions is the first step to keeping it healthy. Here’s how autumn affects your hair – and what you can do to protect it.
1. You naturally shed more hair in autumn
Many people experience a temporary increase in shedding during early autumn. This happens because of the natural hair growth cycle:
Over summer, more hairs are in the telogen (resting) phase.
A few months later, as those hairs complete their cycle, they fall out – usually in September or October.
This mild shedding is completely normal and temporary. However, if you notice significant thinning or patchy hair loss, it could signal an underlying condition such as androgenetic alopecia or alopecia areata.
Tip: Stay consistent with your hair regrowth treatment during this time – it helps maintain healthy hair follicles and hair shafts, encouraging new growth as the seasons change.
2. Cooler weather and central heating can dry out your hair
As temperatures drop, cold outdoor air and dry indoor heating create a double impact: your scalp loses moisture, and your hair becomes brittle or frizzy.
You might notice:
Itchy, flaky scalp
Static or frizz
Split ends and breakage
Try this:
Use a gentle, hydrating shampoo and conditioner
Add a scalp serum or lightweight hair oil to lock in moisture
Avoid very hot water when washing – it can strip away natural oils
3. Lower vitamin D levels – and potentially slower growth
Vitamin D levels can be lower during autumn or winter and could potentially contribute to hair loss.
Tip: If you’re prone to seasonal shedding, ask your GP about checking vitamin D and iron levels – both are important for hair growth.
4. Changes in routine and stress can impact hair health
Autumn often brings back-to-school routines, work deadlines and less sleep – all of which can increase stress hormones like cortisol. High stress levels can disrupt the hair growth cycle, leading to more shedding a few months later.
Try this: Prioritise rest, hydration and balanced meals with plenty of protein and micronutrients (like zinc and/or biotin). These help your follicles stay strong through the seasonal transition.
5. Protecting your hair through the seasonal shift
Here’s how to give your hair the extra care it needs this season:
Stay consistent with your hair regrowth treatment – autumn shedding doesn’t mean it’s not working
Hydrate from within: drink water and follow a healthy diet including foods rich in omega-3 fatty acids
Scalp care: exfoliate gently once a week to remove product build-up
Consider switching to a silk pillowcase: it can reduce friction and help prevent breakage
6. When to seek expert advice
If your shedding seems excessive, lasts longer than three months, or is accompanied by patchy hair loss or scalp irritation, it’s best to speak to an expert. At Hair + Me, our Dermatology Team can assess your symptoms and create a personalised treatment plan using clinically-proven ingredients.
Final thoughts
Seasonal changes are completely natural – but they can challenge your hair’s health. By understanding what’s happening beneath the surface and adjusting your routine, you can keep your scalp balanced and your hair strong year-round.
