Grey Hair in Your Early 20s: Key Precautions for Healthy Hair

Eat a lot of leafy greens, nuts, seeds, beans and dairy products to make sure you're getting enough vitamin B12, vitamin D, copper and zinc, all of which help with melanin synthesis.

Protect hair from UV radiation, which harms melanin, with a hat or scarf. To manage stress, practice yoga, meditation or regular exercise.

Reduce the use of chemical dyes, blow dryers, and hair straighteners, as they can damage hair follicles. Use mild, ammonia free items.

Oxidative stress is brought on by high stress, which also lowers the number of stem cells that produce melanin.

To increase blood flow to the hair follicles, do frequent oil massages using coconut or almond oil. (Disclaimer: Given the input is on an information basis, please seek professional advice.)
