I don't know about agressiveness. If we take the example of areata children, their loss was very agressive.Anyone calling it a scam is just venting frustration...its certainly not a scam...YET....until I see Fidias pictures, results on young people then Im reserving judgement with a dash of hope that it actually is effective on younger less agressive hair loss victims...one thing is clear though Fidia are keeping whatever they have very close to their chests...for what reason remains to be seen.
Now if you talk about young people, you should take into account that their loss can get aggressive really fast. To me sounds like cope, it's like you think that it will only help those in the same spot as you, yet for others it will be useless.
The thing is, there is no proof it even works on Androgenetic Alopecia. Homemade lotion photos do not count.
@PuffyPink that man was old. Transplant surgeons consider hair loss stabilized in older age, it gets really slow or even stops by itself.
