Seasonal Hair Changes Explained: How to Care for Your Hair Year-Round

Why Do Seasonal Hair Changes Happen?

Several environmental factors influence your hair and scalp throughout the year, including:

• Temperature
• Humidity
• UV exposure
• Wind
• Indoor heating
• Air conditioning
• Swimming in chlorine or salt water

Your scalp is living skin. When weather conditions change, your scalp’s natural balance can change too. These seasonal hair changes may lead to increased oiliness, dryness, frizz, irritation or temporary shedding.

Rather than assuming something is wrong, recognising these natural changes can help you make small adjustments before minor concerns become bigger problems.

Spring: A Time of Renewal (and Shedding)

Spring often brings warmer temperatures, but it can also bring noticeable seasonal hair changes, particularly increased shedding.

Many people naturally lose slightly more hair during spring as part of the hair growth cycle. While it can feel alarming, temporary seasonal shedding is usually nothing to worry about.

Your scalp may also begin producing more oil as temperatures rise, especially if you’ve spent winter using richer hair products.

Spring hair care tips

• Continue washing your hair regularly to prevent oil build-up.
• Avoid changing products too quickly if you notice mild shedding.
• Focus on maintaining a healthy scalp with gentle cleansing and hydration.
• Eat a balanced diet to support healthy hair growth.

Summer: Heat, Humidity and UV Exposure

Summer is often when seasonal hair changes become the most noticeable.

Higher temperatures increase sweating, while humidity can cause frizz and make hair feel difficult to manage. UV rays can also weaken the hair cuticle, leaving strands drier and more prone to breakage.

If you swim regularly, chlorine and saltwater may strip moisture from both your hair and scalp.

Common summer concerns include:

• Oily scalp
• Frizz
• Dry ends
• Colour fading
• Sun damage
• Product build-up from sweat and sunscreen

Summer hair care tips

• Wash your hair as often as your scalp needs, especially after excessive sweating.
• Wear a hat during prolonged sun exposure.
• Rinse your hair after swimming.
• Use hydrating treatments to replace lost moisture such as leave-in mists or hair masks.
• Choose lightweight products if your scalp becomes oilier.

Autumn: Seasonal Shedding Returns

Another common period for seasonal hair changes is autumn.

Many people notice increased hair shedding during autumn, sometimes called seasonal hair loss. Researchers believe this may be linked to natural hair growth cycles and changes in daylight hours.

Although seeing extra hairs in the shower or on your hairbrush can be unsettling, this type of shedding is usually temporary.

Autumn is also a good opportunity to repair any damage caused by the summer sun, chlorine or heat.

Autumn hair care tips

• Be patient if you notice temporary shedding.
• Continue supporting your scalp with regular cleansing.
• Increase hydration if your hair feels dry after summer with leave-in mists.
• Reduce unnecessary heat styling where possible.

Winter: Dry Air and an Uncomfortable Scalp

Cold weather brings a different set of seasonal hair changes.

Outdoor air contains less moisture, while indoor heating can further dry both your hair and scalp. This often leads to:

• Dry scalp
• Itching
• Flaking
• Static
• Brittle hair
• Increased breakage

Many people mistake winter dryness for dandruff, but the two conditions require different approaches.

Winter hair care tips

• Use richer conditioners if your hair feels dry.
• Avoid washing with very hot water.
• Add moisture back into your routine with nourishing treatments such as leave-in mists or hair masks.
• Protect your hair from harsh winter weather when outdoors.
