I recommend Hair Plus Protein Bond Ampoule.

I hadn't been using hair products much, but now that summer has arrived, I can feel my hair getting dry and brittle due to the frequent rain and washing.

I usually use perfume often in the summer because of the smell of sweat, but this hair ampoule has such a great scent that it lasts a really long time, so I tried it out and bought it after an acquaintance recommended it.

The name is totally unknown and the case isn't pretty, but I'm satisfied. The scent lasts a really long time!!
