Dear, thank you for your feedback, we are deeply sorry for your problem. But we don't charge you any sample fee, only the transportation fee. Regarding packaging, we will optimize transportation protection measures and feedback on bottle cap design to improve quality. The bottle you mentioned was of poor quality and the lid was opened. Our products have been strictly checked before leaving the factory, and they were all new and unopened when they were sent to you. We regret that the effect did not meet your expectations. Our products usually provide long-lasting color results for our customers, but hair color results may vary depending on hair type and application method. May I ask whether you have conducted tests according to the usage method? Your satisfaction is very important to us, if you still have a problem, please contact us and we will do our best to solve it for you. Thank you for your feedback, which helps us to keep improving. Have a nice day!
