The texture has improved, but the smell is a little strong. I'm still trying different things, but I won't be buying it again for now.
Megamis is a hair-busting shampoo developed by Lion, a major brand. It doesn't have much presence on the shelves, and it hasn't received particularly impressive reviews from hairdressers. Apparently, the fact that you have to use a serum between shampoo and conditioner is what's bringing down its ratings. This time, I used just the shampoo and conditioner without the serum, and it worked fine and was just fine. It left my hair feeling moisturized and slightly heavy.
The shampoo is really good. It's smooth and easy to run your fingers through. The conditioner was a little lacking, but it seems to work well with the serum. I really liked that I could buy a sample size.
Sorry... it didn't suit me. Or rather, I think my hair is just dead. For now, only Tsururincho suits me. I want to keep the price down, so I want to find something good... I've had my hair straightened (hair straightening) and dyed my gray hair. This time, I had my hair straightened, but it's still frizzy, so I'm sorry that this is only helpful to people with dead hair.
The packaging is cute, with a design reminiscent of a tarot card. While it doesn't have any dramatic effects on its own, the sweet scent combined with the mild treatment and conditioner creates a synergistic effect, like a charm that makes hair smooth and silky. I couldn't tell the difference when my hair was wet before using the hair dryer, but once I was about 80% dry, I noticed a slight shine and moisture in my bleached hair, which tends to dry out. I'll continue using it in the winter, hoping to keep my hair moisturized to combat static electricity and make it easier to style. After purchasing it online at Atcosme, I found out it was also available at my local drugstore.
