Since my hair is extremely dry, the Mise en Scène Super Rich Serum suited me better than the Super Serum. I think this serum is probably the "national serum." It is much cheaper than the Moroccan Serum, but the performance is similar, so I think it is the best value-for-money serum. Haha. There may be people who haven't used it, but there won't be anyone who has only used it once. I will use it for the rest of my life. It is a hair serum that I absolutely cannot run out of.
