Unfortunately, the Arren Tea Tree Shampoo was a big disappointment. The composition is of very poor quality, almost just water with minimal formula. It is excessively diluted and does not lather, resulting in not cleaning the hair properly. The smell is indifferent and weak, it does not leave a sense of freshness. It seems like a diluted product and does not deliver what it promises. I will not choose it again

Good shampoo but for its price, not something special. Slightly better than commercial ones, at double the price. If you want something incredibly high-quality that will make your shower a real pleasure, try the tea tree from Paul Mitchell. It's very expensive but worth every € and requires very little for each wash. I thought this one would be, if not the same, at least at similar levels but unfortunately it isn't...
