There is a cure for white hairs...if u suffer this condition before optimum age.
The most simple way for get them right...back as black is to perform a simple exercise.u just have to rub the finger nails of both of ur hands.just coil ur hands like a snake...nd then rub the finger nails of one hand on the other hand vertically.it is likely to work in most cases.performing this exercise for 5 minutes daily will help in longer turn.u can consult a doctor...preferabily a homeopath or ayurvad...coz homeopathy and ayurved are the two branches which are quite handy in the case of greying of hairs. Phyllanthus emblica(Indian gooseberry
or amla) is considered more than handy for white hairs.using amla in any form is likely to get this problem right.u can use it either in form of oil or syrup or can simply intake as fruit,pickel,paste etc.
These simple formulas will surely help u.
+ u can use mehndi(a natural dye)...which although will give brown colour but is handy.using mehndi with sugar less black tea will give brown-black colour

If ur hair is dark brown u can naturally dye it with coffe yeah Ikr weird but it's true caffe can dye hair I would explain it but it's alot of typing lol so just look up on YouTube dyeing hair with coffee tutorial it works lol or u could just pluck them out but u would go bald lol

Other than dying it, maybe use hennah. My mom's friend uses it instead of dying her hair. But her hair is dark, so depends what your hair color is. If its light.. I suggest you dont use it..unless you want redish orange hair.

If you aren't going to dye them then if it isn't taking up your roots or a majority of your hair, just pluck them.

No cure, dude, otherwise no one would have white hair.

A nice tall glass of chill the **** out.
