Tepelné poškození vlasů: jak ho poznat, způsobit a opravit

When your hair feels dry, brittle, or looks like it’s fraying at the ends, you’re likely dealing with tepelné poškození vlasů, poškození vlasů způsobené příliš vysokou teplotou z horkých nástrojů. Also known as termální poškození, it happens when heat strips away the hair’s natural moisture and weakens its protein structure—no magic cream can undo it overnight. This isn’t just about looks. It’s about your hair losing its strength, becoming prone to breakage, and eventually falling apart strand by strand.

Most people don’t realize how fast heat damages hair. A flat iron at 200°C can fry your strands in under 10 seconds. You think you’re just styling, but you’re actually cooking the keratin—the same protein that gives your hair its shape and resilience. Over time, this turns smooth hair into straw. And no, not all "heat protectants" fix this. Many are just fancy oils that sit on top and wash off. Real repair needs to go deeper. That’s where vlasový keratin, přirozený protein, který doplňuje poškozené vlasy a obnovuje jejich sílu comes in. It doesn’t magically seal your hair like a bandage—it fills in the gaps where heat burned away the structure. But it only works if you stop the damage first.

That’s why you also need to look at what you’re washing your hair with. Many shampoos contain sulfáty, drazdivé látky, které vysušují vlasy a odstraňují přirozené oleje—and if your hair is already heat-damaged, these will make it worse. You can’t repair what keeps getting stripped. The same goes for overusing heat tools. If you’re blow-drying every day and straightening twice a week, you’re asking for trouble. Your hair needs rest, just like your skin does after sunburn.

What you’ll find in these posts isn’t a list of expensive treatments. It’s real, practical advice: how to tell if your hair is damaged beyond repair, which products actually help (and which are just marketing), how often you can safely use heat tools, and what to do when your hair starts snapping off. You’ll learn why keratin treatments aren’t a cure-all, how to pick a shampoo that doesn’t dry your hair further, and what simple habits make the biggest difference. No fluff. No hype. Just what works when your hair is tired, dry, and begging for help.
