Winter Hair Care: How Cold Weather Affects Your Scalp

Why Winter Is Hard on Your Scalp

As the days grow shorter and the air turns crisp, many of us notice changes in our hair and scalp. Cold, dry winter air strips moisture from the scalp, disrupting its natural balance and leaving it vulnerable to dryness, flakiness, and irritation. Add indoor heating into the mix — which further depletes humidity — and your scalp can quickly become parched and unhappy.

The result? Increased shedding, a tight or itchy scalp, and hair that feels brittle and dull. If you've noticed more hair on your pillow or in the shower drain as the temperature drops, you're not alone.

The Science Behind Winter Hair Loss

Hair growth is cyclical, and seasonal shifts can push more follicles into the shedding phase (known as telogen). Cold weather also causes blood vessels near the skin's surface to constrict, which can reduce circulation to the scalp — meaning your follicles receive less of the oxygen and nutrients they need to thrive.

A well-nourished, well-stimulated scalp is the foundation of healthy hair growth. That's why winter is exactly the time to be intentional about scalp care.

Our Approach: Rooted in Nature, Guided by Heritage

At Tui and Moon Botanicals, our approach to hair care is deeply connected to the land and to the wisdom of our tīpuna (ancestors). We believe in working with nature rather than against it — using locally sourced New Zealand botanicals that have been trusted for generations to support wellbeing from the roots up.

Our formulations are crafted with care, combining traditional plant knowledge with modern understanding of scalp health. Because we believe that what you put on your body matters just as much as what you put in it.

Introducing: Rosemary & Caffeine Scalp Spray

Our hero product for winter scalp care is the Rosemary and Caffeine Scalp Spray 100ml — a natural, targeted treatment designed to stimulate the scalp and support healthy hair growth.

Here's why it works so well in winter:

• Rosemary is a powerhouse botanical known for its ability to improve circulation to the scalp. Better blood flow means better delivery of nutrients to your follicles — exactly what they need when cold weather is working against them.
• Caffeine has been shown to stimulate hair follicles directly, helping to counteract the effects of seasonal shedding and encouraging the growth phase.
• Together, these ingredients create a synergistic effect that wakes up a sluggish, winter-stressed scalp and gets things moving again.

At just $24.99 NZD, it's an accessible, effective addition to your winter wellness routine. Want to stay stocked all season? Our 300ml Eco Refill keeps you going without the waste, or grab the Scalp Spray Duo and save.

5 Tips for Healthy Scalp Care This Winter

1. Apply your scalp spray consistently. Use the Rosemary & Caffeine Scalp Spray regularly — consistency is key when it comes to scalp stimulation.
2. Massage your scalp daily. Even just 3–5 minutes of gentle scalp massage each day can significantly improve circulation. Apply your spray first, then use your fingertips (not nails) in small circular motions.
3. Wash with lukewarm water. Hot showers feel amazing in winter, but hot water strips the scalp of its natural oils. Opt for lukewarm water when washing your hair to preserve moisture.
4. Don't skip hydration. Drinking enough water in winter is easy to forget, but internal hydration directly affects scalp health. Herbal teas are a lovely way to stay warm and hydrated.
5. Protect your hair from the elements. Wind and cold air can cause breakage and moisture loss. Wearing a hat or scarf (lined with silk or satin if possible) helps protect your strands while keeping you cosy.

A Note from Melanie

Tui and Moon Botanicals was born from my own experience with postpartum hair loss — a deeply personal journey that led me to explore the healing power of plants and reconnect with my Māori heritage. I know what it feels like to watch your hair change and to feel powerless about it.

Winter can amplify those feelings. But I also know that with the right care — gentle, consistent, and rooted in nature — your scalp can thrive in any season. That's what we're here for.
