Summer creates new challenges for every hair type, but hair extensions require even more attention. Strong sun exposure, chlorinated pool water, and sea salt affect extension hair and keratin bonds differently than they do during the rest of the year, making a few seasonal adjustments essential. If you're planning to refresh your look before summer, it's worth choosing the extension method that best suits your lifestyle. Some people prefer hair extensions for short hair, which dry more quickly and are easier to manage after swimming, while others choose discreet micro hair extensions or virtually invisible nano hair extensions for the most natural finish.
