Hi

hope you doing well

No, having grown hair and a beard compared to your ID photo should not cause any issues during the JEE Main exam. Identity verification is primarily focused on matching your key facial features and ensuring your documents are valid.

Even if your appearance has slightly changed, as long as your essential features (eyes, nose, face shape) remain recognizable, there should be no issue.

Ensure that the photo ID (like Aadhaar, passport, etc.) is the same as the one mentioned during registration.

If the invigilator raises a concern, you can politely explain the reason for the change in appearance due to religious or ritual practices. Most officials are accommodating in such cases.

Hope you get it and find this information suitable

Best Wishes.
