My scalp looks thin these days, so I'm considering Pantodil hair ampoules.

I attended a friend's wedding last weekend, so for the first time in a while, I dressed up in a suit and styled my hair nicely. However, perhaps because the lighting at the wedding venue was so bright, the crown of my head looked particularly sparse every time I looked in the mirror, and it kept bothering me. I never used to worry about my hair thickness, but perhaps due to a lot of stress, my hair definitely feels weak and thin. So, I decided I needed to provide some direct nourishment. I looked around and found that the reviews for the Pantodil Hair Ampoule looked quite good. Since it is applied directly to the scalp, I think it will absorb quickly, and the ingredients seem gentle, so I am interested. I am wondering if anyone who has used the Pantodil Hair Ampoule experienced any stickiness or greasiness. Since I have an oily scalp, I am worried that if it is too rich, it might actually cause breakouts. If I use the Pantodil Hair Ampoule consistently, will it definitely help restore volume to my roots? I would appreciate honest advice from those who have used it.
