Actually, you can tell whether a bottle of shampoo is organic. Sometimes it is very simple to just smell it. Some products with added chemicals can smell the fragrance when you smell it. But apart from smelling it, In addition, everyone should also choose a trustworthy brand. The Firefly shampoo I have been using is very good. It is made from all plant extracts and does not contain silicone oil. It also has a very natural plant fragrance and is very good for your hair. You can buy it and try it.
