This serum was recommended to me at my brick and mortar Kbeauty store. I was given a sample and skeptically took it. I washed and conditioned my type 4 hair and applied the serum and went to bed. The next morning, my hair was soft, felt moisturized without being greasy. The moisture lasted for a few days (I used to wash my hair daily since it’s so short and it’s hot and humid here).
I immediately purchased several full sized ones from here. I travel with it and a little goes a long way and lasts a while. No regrets.
