I noticed a collection of unused shampoos and conditioners hidden in a box while clearing some items in my room recently. They were part of a review project I worked on last year and I never got round to finishing them up, mostly because they either do not suit me so well or because I’ve moved on to try other things. Anyway, of the lot, the Intelligent Nutrients Harmonic set is most interesting as it is made with non-toxic chemistry, and its unique selling point is being gluten free. And boy, after a year, they’re still usable!
