My experience:
I also had bad bad experience there. I choosen the
middle price 染髮劑, but i found that they gave
me the cheapest one. And I saw the rabbish bin that they disposed the 染髮劑 包裝 was full of the cheapest ones brand. I think they gave all customers the cheapest brand eventhough they choose the more expensive one.
I 揭發them immediately. they "explained" that the technician
可能聽錯,so gave the cheapest one to me. Then they 開過another one for me. But the quality was still very poor.我染完後洗頭洗左成個幾兩個月個頭仲甩色. I definitely would not go there anymore
