Although researchers are still looking for a way to reverse gray hair, you can adopt lifestyle changes to help slow the process of your strands turning silver. Like hair loss, the sooner you begin managing gray hair, the better your results. Keep in mind that these are temporary measures and they won’t altogether prevent your hair from graying.
Dermatologists say following these habits may help delay gray hair:
Maintain a healthy lifestyle
Eat a balanced diet containing antioxidants, vitamins, and minerals
Get a good amount of sleep
Don’t smoke
Try to manage stress
Protect your skin and hair from the sun’s harmful UV rays by following the tips at Practice Safe Sun
A board-certified dermatologist can diagnose and treat an underlying condition causing gray hair and help create a plan to manage it. To find a dermatologist near you, go to Find a Dermatologist.
