The short version
- Condition after every wash.
- Shampoo based on your scalp, not the calendar.
- Use lower heat settings and a heat protectant.
If your hair feels drier, frizzier or more prone to breakage once the heat comes on, you are not imagining it. Cold outdoor air and dry indoor heat pull moisture from hair, especially if it is already dry, curly or color-treated.
Condition every time
Dermatologists with the American Academy of Dermatology recommend using conditioner after every wash. If your hair is fine or straight, focus it on the ends. If it is dry or curly, work it through the full length.
Rethink how often you shampoo
Shampoo based on how oily your scalp gets, not on a fixed schedule. The AAD notes that people with oily scalps may need to wash daily, while those with dry, textured or curly hair may wash much less often. Apply shampoo to the scalp rather than the full length of your hair.
Turn down the heat
Winter is a good time to give hot tools a break. When you do use a blow-dryer, flat iron or curling iron, choose a low or medium setting and apply a heat protectant first.
Small seasonal swaps
- Add a weekly deep-conditioning treatment for an extra dose of moisture.
- Air-dry when you can, and avoid going outside with wet hair in freezing weather.
- Choose soft hair ties and silk or satin scarves or pillowcases to reduce friction.
- Run a humidifier in your bedroom if the air feels very dry.
The takeaway
More conditioning, less heat and gentler handling go a long way in winter. If you notice sudden shedding or scalp irritation, check in with a dermatologist.
