Examine your hair for a second. Does it look dry, frizzy or dull, or even break in some places? You could have a protein problem. 90% of your hair is made up of protein – but a constant barrage of hairstyles and treatments (like this summer where you decided to opt for platinum blonde) can dissipate at the level of the hair's natural proteins to leave damaged locks.
That's why stylists and dermatologists (and even Kim Kardashian!) Are obsessed with protein treatments. "They strengthen the hair, protect it from excessive moisture loss, make it thicker and shinier and, to a certain extent, repair the damage," says dermatologist Francesca Fusco, of Wexler Dermatology in New York. They usually come in the form of conditioners, serums or masks containing high levels of protein to help repair the broken proteins in your hair to make it stronger and healthier.
Protein treatments are not necessarily new, but formulas have been refined and improved in recent years to provide the best possible results. And, depending on your level of damage to the hair, you may need a different intensity. If you overuse the protein, your hair may become stiff and, ironically, prone to breakage. So we divide the type of protein treatment that suits you best – and how to avoid going too far.
