Hair damage, though common, is a different experience for everyone. Between the heat tools and the dying it can manifest in the form of breakage and split ends. It can also feel rough in texture or break off when you brush it, and sometimes, no matter how often you attempt to treat it with a repairing mask, it can feel like not much is helping.
It can be frustrating not to know the root (no pun intended) of your hair issues, and it's even more frustrating to know what's wrong and not know what to do about it — despite how many times you've tried to google an answer. For that reason, we spoke to Stephanie Riley, a chemist at Procter & Gamble — the parent company to some of our favourite hair brands like Pantene, Head & Shoulders, and Herbal Essences — to get some insight on how to treat and repair hair damage.
