At this time, Qin Lang and Su Shihan are on their way to Zhonghai University.

At this time, it is already more than nine o'clock in the evening. In another hour, the university will begin to implement night access control.

Su Shihan is a student of Zhonghai University and is familiar with the road here.

The two came to the downstairs of Building 9 men's bedroom. Su Shihan said, "Qin Lang, I can't get into the men's bedroom. Take your mobile phone and remember to record all the conversation later. The other party's slander behavior. If he doesn't want to solve it well, we'll take the legal way."

Qin Lang nodded and took down the scarf from his neck and tied it around her neck.

"It's a little cold. If you feel cold later, go to Aunt SuGuan and wait for me first. I'll go up and solve it as soon as possible."

"OK, I'll wait for you." Su Shihan said.

Qin Lang went directly to dormitory 323. After knocking on the door, a boy in a hat came to open the door. As soon as he saw Qin Lang, the boy subconsciously wanted to run back and was dragged back by Qin Lang.

"Run what?"

As soon as Qin Lang opened his mouth, the other party came back and raised his head: "let go! Who are you? How can you break into other people's dormitories?"

"Are you here to make trouble? I tell you, the security guards of Zhonghai university are not vegetarian!"

Qin Lang smiled and loosened his collar, flicked the dust on his hand and said, "it seems that you know who I am, and you should also know that I came for the post!"

Ding Rui was a little flustered. He avoided his sight and said, "what post? I don't know what you're talking about. Go quickly. If you don't go again, I'll call security."

"Classmate, I'm the person in charge of Qin's shampoo. I saw a post on the Internet that you used our Qin's shampoo to cause serious hair loss. As the person in charge, I'm here to deal with the after-sales problem today."

"After using our shampoo, you didn't contact our after-sales customer service for the first time or call our after-sales phone. Instead, you chose to send such a post online. I can understand that you don't want to contact us actively, so I took the initiative to come to you."

"In the post, you mentioned that after using our shampoo for half a month, a lot of hair fell off your head. Now can you take off your hat and let me have a careful look?"

Ding Rui was terrified when he saw Qin lang. he thought Qin Lang was looking for trouble, but Qin Lang suddenly spoke so well that he was even more flustered. He didn't know what Qin Lang was going to do.

He remembered what Zheng Feiyu had told him. Qin Lang suffered in this matter anyway.

Qin Lang is a businessman and must consider the reputation of shampoo. Therefore, even if he is found, he does not dare to do anything to him. He will only choose to spend money to calm him down. After all, Qin Lang will not want this thing to continue to ferment.

Originally, Ding Ruixin was quite afraid, but he just saw the reaction of the situation. He thought Zheng Feiyu was right. Qin Lang was afraid. Even if he said so about the shampoo sold by his family on the Internet, he could only talk so well when he saw himself.

Ding Rui immediately calmed down, took off his hat and said, "OK, since you came to the door yourself, then solve this problem well. Look at the two large bald patches on my head now. I can't go out without a hat every day. All this is caused by your shampoo!"

Qin Lang took a close look at his scalp, and the idea in his heart was immediately confirmed. This is indeed the effect of depilation cream, definitely not the hair follicle caused by natural hair loss.

Qin Lang took a picture quickly.

Ding Rui was angry, put on his hat and said, "what's wrong with you? Why take my picture! I can sue you for violating the right of portrait!"

Qin Lang smiled and said, "don't worry, classmate, I'm just taking a picture of your head for evidence collection. You're so excited that you seem guilty. Haven't you posted these pictures on the Internet anyway?"

"Who is guilty? I have no problem. You are the one who has the problem!" Ding ruidao.

Qin Lang said, "now please show me the certificate of buying shampoo in our store and the shampoo you have used. Please take some of it for me to test and see if it is the shampoo in our store."

Ding Rui glanced at him, turned to the cabinet and took out shampoo and hair lotion.

These were all prepared according to Zheng Feiyu's instructions. He bought the things and deliberately squeezed out the upper part of both, which looked like they had been used.

Qin Lang saw the two bottles and turned to smile.

Ding Rui said humbly, "Why are you laughing? Dare you say this is not your shampoo? I bought it at your official website store!"

Qin Lang said: "yes, this is indeed our shampoo and hair lotion, but you should also receive a manual when you buy it. The product manual clearly says that you should use the shampoo for one month before using the hair lotion. You say you have used our product for half a month, but how can you use the hair lotion in the same amount as the shampoo?"

Zheng Feiyu gave it to him. Of course Ding Rui didn't read any instructions.

Hearing Qin Lang's words, He said angrily: "I didn't read any instructions, but your shampoo focuses on hair removal solution and hair growth. Even if you use it together, it should not lead to hair loss. The problem of hair loss is that your shampoo and hair growth solution can't work. If it works, no matter how I use it, it won't have a negative effect!"

"This is true. Even if the hair tonic is used with shampoo, it will not lead to hair loss." Qin langdao.

Ding Rui breathed a sigh of relief and said, "you have admitted it yourself. That means there is a real problem with your shampoo. Do you still need to take it for testing?"

"No, it belongs to our family. I can recognize it." Qin langdao.

Ding Rui sat on the stool and said arrogantly, "since you admit it yourself, let's talk about compensation!"

"Don't worry, classmate Ding Rui, right?" Qin langdao.

Ding Rui looked at him with a bit of doubt and confusion in his eyes, "yes, I'm Ding Rui. What's the matter?"

"The store on our official website just sent me your order. Your order is from the previous day. It was received by SF express this morning. What did you say it took half a month?"

"Also, you said that our shampoo and hair lotion caused your hair loss. I'm very curious. How can hair loss make your hair follicles and hair roots so neat? It's completely like using hair removal cream?"
