Cha-Tra-Mue faces the problem of brand image that can be perceived as only for old people and does not represent young generation. In 2017, Cha-Tra-Mue has become a great success in reaching all generations by changing its sale strategy. The management of new young generation operates the business more understanding what the target needed. For instance, the very popular product which brings Cha-Tra-Mue back to the market is “cha-kulharb” (Cha=tea, kulharb= rose)

Due to the social media has gone viral about this tea as a detox tea because the ingredient and the effect of drinking it. The main attribute of rose tea for health such as detoxification, improve digestive system, healthy skin, nervous system and reduce fat in the blood.


The quality of rose tea cannot be popular without social proof. It is one of the psychology of persuasion defined by Robert Cialdini. Social proof in Cha-Tra-Mue can clearly be seen as word of mouth; from consumer to another consumer. For example, when first consumer drank rose tea and really want to go to the toilet, they think it is very effective tea then they told other friends. So, from word of mouth of your friends can be both users and wisdom of your friends social proof. For the former means the real customer’s review, the latter is from your friends which persuade you to buy follow them. Another key to announce the property of rose tea is to be published in the online channels that also lead people to buy. This will be the social proof in section wisdom of the crowds, which many people think it is good, then follow. Moreover, many consumers face with defecation after drink rose tea, therefore, some doctor has proven which is an expert social proof that this tea does not put any medicine to help detoxification but use all natural elements instead. Furthermore, Thai celebrities also post and review this tea which becomes celebrity social proof.

Basically, customer behavior showed that people want to try new thing like try the power of rose tea and challenge with it. Some of them want to try because of their defecation problem. On the other hand, the popularity of slim body might be the factor that consumer buy because it is a detoxification. Thus, they would buy detox tea which recommended by expert than buy medicine to solve defecation issue.

For example, According to LALANDE (2016), Thailand was ranked two from ten of Asean Economic Community of an obesity problem. Trend of healthy and slim body is the significant factor for Thai people. Some people think that often defecate can make them get slimmer and healthier. So, people who have difficult excretion might have rose tea as a way to help them because it sounds safer than take slim pills.

Cha-Tra-Mue produces other flavored milk tea and creates product extension, which is soft serve ice-cream apart from beverages. Additionally, the package has also changed but remains its original logo brand for the concept of long prominent tea in Thailand.
