If you have only a few grey hairs, colouring hair at home is easy and economical, but bear in mind that grey hair is the hardest to cover it is not like adding a few highlights to your existing hair, so you’ll need a home hair dye that is permanent (permanent doesn’t mean forever, though – this is not a dyed and gone to heaven scenario; you have to keep working at it!).
Which shade do I choose?
Whenever you pick a home hair dye consider your skin colour and your natural hair colour – not the grey bits, obviously! It’s also worth bearing in mind your eye colour and the kind of clothes you wear, but a rule of thumb is to avoid a drastic change from your original natural shade; choose colours that are only a shade or two lighter or darker, so that when your roots grow through they will be less visible.Expert colourists recommend a darker shade of dye for your roots and a lighter shade, that matches more or less your natural hair colour, for the rest of your hair. Start by applying the darker dye to the roots up until an inch or so down. Then, use the lighter shade for the rest of your hair.The best hair dye for grey hair if you have blonde hair
The great news is that your stubborn greys are very easy to cover as the colour is not too far removed from the grey. Think of Helen Mirren; is she grey or is she blonde? Who cares? She always looks amazing. Generally, natural blondes with a complexion of warm, pinky tones are best opting for a honey blonde colour, while those with cooler, yellowy skin tones are more suited to icy-blondes with blue undertones.

The best hair dye for grey hair if you’re brunette
You won’t be surprised to hear that you should be covering the grey with brown dye, but the best hair dye for grey hair here is a medium-light shade, even if you are naturally very dark, as this will complement your naturally paling skin.

Yes, that’s right; skin ages too and it tends to become paler. So, whilst you can cover up grey hair with any colour, if you want it to look natural you do need to take your ageing complexion into consideration. As your skin becomes paler, a dark hair colour, or something dramatic like a fiery red, can look too harsh and might age you further, whereas a more forgiving shade with hints of chocolate, or light balayage highlights will keep your face illuminated and youthful looking for longer.
