In the words of Amy Winehouse - what kind of fuckery is this? It stripped build-up or what? What could be the explanation?
I've bought Olaplex, Kerastase and Philip Kingsley for years. Today I washed my hair in Palmolive washing up liquid at the kitchen sink and it's looked the best it has in ages! I just suddenly felt like doing it. It's the softest and shiniest it's been in years.
I don't know what to think, I'm feeling a bit twitchy.

It was Palmolive, 2 quid.
