For the rest of the year, your hair is at home. It has its hairdryer. Its wax. That hairstyle you've been perfecting for years… but then summer arrives… and the rules change.
There's the chlorine, which dries out your hair. The salt, which doesn't help make it soft either. The wind, which dismantles in seconds the small feat of engineering that is that scaffolded quiff. The constant showers. The air conditioning. And, of course, that hotel shampoo that seems formulated to clean the extractor hood from Kitchen Nightmares.
I'll tell you, you and your lifestyle are no slouches either: you go from the sea to the pool, from the pool to the terrace, and from the terrace to another dip. If you also play sports, wear a cap, a helmet, or simply sweat more than usual... keeping your hair styled becomes mission impossible.
However, if we had to point to the biggest culprit for causing hair defects, it would be the sun.
As the days go by, hair tends to lighten slightly. It seems like a minor detail, but with less contrast between the hair and scalp, the receding hairline and crown become much more noticeable. On top of that, the summer light comes directly from above—exactly where it's least flattering and most scorching.
In short; summer doesn't increase your hair loss... but it shines a spotlight on it, literally.
