White hairs are usually seen as a sign of getting old, so it's understandable that you want to get rid of them. Luckily there are several things you can do to cover up white hairs, prevent more from growing and even reverse the process. 

Eat a healthy diet - Maintaining a healthy, balanced diet plays a huge role in the health of your hair, so making sure your body is getting all the hair-friendly vitamins and nutrients it needs can help to prevent white hairs. 

Give regular head massage - Head massages help to stimulate blood flow to the scalp, which keeps hair growing healthily. If possible, massage a natural oil like almond or coconut oil into the scalp, as this helps to deeply moisturize the hair roots.

Avoid poor quality hair products - Poor quality hair products are full of chemicals such as sulfates, phosphates, chlorine and ammonia which dry out the hair and weaken the roots, making you more prone to white hairs. Therefore, you should stick to hair products with as many natural ingredients as possible.

Quit smoking - According to one study, smokers are four times as likely to have white or grey hairs as their non-smoking counterparts. Smoking also causes hair to look dull and brittle and makes it more prone to falling out.
