2 months after hair transplant (FUE), I need to start using a safety helmet. Does it have any effect on growth or hair loss?

Two months past from your hair transplantation surgery ,so you can use a helmet and it will not cause any problem as your transplanted area is healed.

There should be no issue but it is best to check with your doctor who performed your surgery in case there are issue specific to your surgery.

It should be okay to do so at this time. You want to avoid injuries to the grafted areas as this may hamper your growth.Goodluck

At this point there is no restriction on what you can wear on your head-safety helmet,motorcycle helmet-no problem!

There should not be any problems wearing a safety helmet. Sometimes wearing hair pieces after a transplant can cause growth issues.

At two months post op you can wear a safety helmet and it will not effect your growth. Just make sure the inside of the helmet is clean. 

2 months past your procedure, your transplant is fully healed and the grafts are essentially just as strong & permanent as your regular hair. At this point you can do whatever you'd normally do as if you didn't have a transplant without worry, including wearing a helmet. It wouldn't hurt to check with your doctor in case there's something unique to your procedure that would change this but if you're healing process has been normal then you should be fine.

Two months after a hair transplant you can use a helmet without any difficulty and it should not impact the growth of the hair
