I have been using Korean red ginseng hair essence and tea tree biotin together.
I'm surprised to see that many people have dandruff;; In my case, the dandruff has actually disappeared, and while I'm not sure about the hair texture, it definitely feels good on my sensitive scalp.
At some point, I suddenly started getting a lot of acne on my scalp that wouldn't go away, so I started using these products, and while there wasn't a dramatic effect, the consistent use has made my scalp cleaner.
The thing that used to come out and make my scalp dirty has disappeared.
It's good that I don't have to use conditioner or treatment anymore.
I'm not sure if it's good for my hair texture. It seems to make my hair feel stiff. But it goes back to normal after drying.
And the price......ㅜㅜ
Depending on when I wash my hair, I use the Korean red ginseng hair essence in the morning and the tea tree biotin in the evening.
For oily-haired people, tea tree might be better than red ginseng, and for dry-haired people, red ginseng might be better.
