This is one of those ideas that once you hear about it you can't imagine why no one thought of it before. I find doing hair masks annoying because unless one is soaking in the bath you get cold waiting in the shower for it to work. So, finding this multi-tasking wonder was a proper lightbulb moment. You spray it on dry hair just before a workout session and the heat from your head as you sweat activates the treatment for some deep moisturisation, plus the essential oils release a calming aroma that centres you as you downward dog. It makes my coloured hair soft and shiny again.
