You are required to shave or trim your hair to achieve the release from Ihram.

 

If the machine or scissors remove the hair wholly, then it is reckoned as shaving and fine. If, however, they only trim or cut the hair without removing them altogether then it is sufficient to fulfill the requirement of trimming or cutting.

 

After having said this, it is always best, in the case of doubt, to follow the safest.

 

Almighty Allah knows best.
