I personally would never go with Beauty Travels 24. They have a very negative image on the german discussion sites, they do a lot of advertisement, and are trying to catch hair loss patients with cheap prices and statements, that everybody who is at least a little engaged in HTs would consider simply as ridiculous.
They are also suspicioned with lots of hidden promotion. You don`t find anybody that you would attest credibility due to a forum history or so that would ever endorse them. Contrary, everyone that posts positive reviews about them only just registered, pictures or a documented history are never delivered.
Antic information such as about the breakfast, the hotel quality are made. One user told about 5 doctors being present at the surgeries, wich tends to impress complete newbies. That`s also the tenor of the posts: That totally unexperienced folks, that are on the search for cheap HTs, google the term and find threads such as this one here.
Although they are years in the business, there is NOT A SINGLE documented case as far as I know, it`s up to you to decide what that means.
The promotion policy is very obvious for people who have a brain and can think for themselves, unfortunately, still enough people are taken in anyway. In every case, I would take every strange endorsement about them with a pinch of salt.
I can only advise people: Do a good research, otherwise you`re gonna regret it for the rest of your lives. There are so many great surgeons with a good and comprehensible reputation, that even can be a good decision, too, if you factor the costs. Good luck to you all!
