Can I use Creatine supplements after hair transplant? Does Creatine lead to hair loss ?

In general hair loss in men is due to genetic balding.  Creatine does not cause male pattern hair loss.

Voris, 
I do not believe creatine leads to hair loss. Male pattern hair loss (androgenic alopecia) really comes down to genetics. Either your follicles are prone to hormonal hair loss, or they are not. There may be some mitigating factors that can "set off" the loss a little sooner; however, any hairs you lose were genetically programmed to "fall out" eventually. And I don't really believe creatine in-and-of-itself will "set off" the loss. 
You need to speak with your clinic about re-starting the creatine. All clinics have slightly different post-operative instructions, and you must follow your doctor's instructions "to a T." 
Hope this helps!

When this substance has a steroid with it, it does cause hair loss and many people find this out too late.
