Hi Stella,
Thanks for your question!
Both products are deep cleansing for the hair ☺️
Bobby's Hair Care Detox Shampoo is based more on natural extracts and plant-based care.
L'Oréal Professionnel Metal DX, on the other hand, contains silicone compounds and nourishing ingredients that smooth and add shine — good for treated or frizzy hair.
I would say that the most significant difference between the products is the nourishing plant extracts, of which this product has more compared to Metal DX 🌱
Hope this helps!
Have a lovely day 💛✨
