“If the hair is dehydrated or overprocessed from chemicals or overheating with appliances, the best approach to repair the hair is with professional salon treatments combined with at-home treatments over time,” says hairstylist Michelle Cleveland. “This works best for this type of damage because the treatments will penetrate inside the hair shaft to help repair the bonds that make up the strength of the hair.

On the other hand, if the hair is broken and split, the best approach to repair it would be to combine both treatments mentioned above with regular haircuts. The reason haircuts work best, in this case, is because once the hair is broken or split at the end, there truly is no way to repair it.”

As Cleveland says, if your hair is truly broken and full of split ends, it might be time to schedule a trim—a half inch or so off the ends never hurt anyone. You may also need to space out your coloring appointments or look into trying a new colorist. Otherwise, there are plenty of products out there to mitigate damage. Just look for bond-building products with nourishing and hydrating ingredients like argan oil, peptides, shea butter, and more.
