I have used Bigen hair color in Oriental Black (#59) for the last 4 years, and I will never try another hair color! Its absolutely amazing. In 2001, I used Dark and Lovely Permanent in Midnight Blue, and it made my hair so dry...my stylist then said that it did the same thing to her other clients. I retouch my roots 2 weeks after touch-ups with Bigen, and I refresh the ends with a semi-permanent such as Beautiful Collection. The color lasts very well for me. I noticed in the BSS last week that they have a new Bigen haircolor (blue-black # 60?)...this oriental black is dark enough for me, I think!
