The solution made by the teacher after hair transplantation

Hello everyone. I had hair transplantation about a month ago. Hodja Erkan Özgün, who made the cultivation, proposed his own hair solution. Her hair is more bushy and the hair growth process is faster.
The teacher told me to use it for a year. The price is around 1000 TL. A box goes for 4 months, my guess
To take it in the process because of the coronavirus.
On the other hand, there is a little fear.
I use Xpecia Men’s Tablet and Replexion GF Shampoo.
If I don’t use the solution, what happens if I lose?
How much does this solution affect the hair output?
I would appreciate it if you could help my brothers who live or know the same situation.
