TiGi Moisture Maniac is by far the worst shampoo I have ever used, including drugstore brands. It absolutely did a number on my scalp, completely dried it out and I had scabs everywhere from it! Also, it dried out my hair completely. I had to go to a pharmacy and get a special medicated shampoo to sort out the issues the TiGi one caused. ABSOLUTELY WORST SHAMPOO EVER!
The Dove shampoo & cond for coloured hair is another horrendous product. Build up like you wouldn't believe and the smell is overpowering. Yuck.
Sometimes I go back to drugstore stuff just to try it out and save some money, but the results are so terrible that I just stick with my good quality, albeit expensive, salon products.
Oh also, the L'Oreal Studio Line styling products (remember the packaging straight out the 90s), do absolutely NOTHING!
It's weird because the L'Oreal Professionel products are really amazingly good.
