I have thick, coarse, and slightly curly hair. I previously purchased the hair milk, but it was a bit disappointing, so I wasn't interested in buying it again. However, I saw it at half price at the drugstore, so I gave it a try. I use about five pumps (for medium-sized hair) after a bath before drying my hair. If I let it dry, it tends to get frizzy, but it calms and manages. I've also tried N Polish Oil, Milbon Hair Milk, oil, Orbis Hair Milk, and MEDULLA Hyperlink Serum, which I often see on social media, and this is the best. It's not unpleasantly sticky, and it has just the right amount of manageability, which suits me. As for Hyperlink Serum, it wasn't cheap, so I had high hopes for it, but it didn't live up to my expectations, so I was disappointed. This is the first hair oil I've ever wanted to repurchase.
I have both Moist and Moist Light. I like the scent of Moist Light better and it's easier to use. I use it before blow-drying and it keeps my hair moisturized. I have a short bob, but it's not sticky and easy to use. I also recommend using it as a styling oil. The amount is easy to adjust and it lasts a long time, so if you have trouble with wavy or curly hair, it's worth having one.
I've been using this before going out recently. If you use it before using a flat iron, you can create beautiful straight hair. Compared to oils that require heat for their effects, this oil doesn't have an oxidized smell after application, so it's easy to use.
I ran out of N. Polish Oil, so I bought this in a hurry. I only used it before blow-drying. It leaves my hair feeling moisturized. I felt it was better to use it than not to use it. I don't plan on buying it again. It doesn't have to be this one.
I've tried a lot of different hair oils, but this is the first one I've repurchased. What I like most about it is that it doesn't leave that typical oily smell after a few hours of use! Other hair oils are either too strong in fragrance or develop an oily smell over time, but this one works without any problems. Another plus is that it has a shape memory function, so if you use it after a bath while drying your hair, it won't get messy.
