When hair starts turning grey, most people begin to colour it to cover the grey and the inconsistency. There are only two choices to make when the grey roots begin to come in: the roots can be retouched or you can grow out your hair.
Allow the roots of your hair to grow out by not placing any more permanent hair colour on your hair.
Wear a headband to temporary conceal grey roots. Brush hair back in a straight design and wear a headband at the forehead to conceal the hairline.
Wear a bandanna to cover up larger growing roots as time goes by. Make sure the bandanna covers the hairline at the beginning of the forehead as well as the back of the scalp on the top of the head. Keeping these areas covered will conceal the grey hair that is growing in.
Apply a temporary colour to your roots that will last for one to a few washings. This will not have a permanent effect on growing out your grey roots.
Visit your cosmetologist or barber to have your hair trimmed. This will cut out any colour that you do not want in your hair allowing the grey to grow in and take over faster. Ask the cosmetologist about having the current colour in your hair stripped.
When purchasing temporary hair colour be sure it does not contain peroxide as this will stay in the hair permanently. Go for a short haircut to be able to cut out most of the grey and make the whole process shorter. Experiment with brushing your hair in a certain direction and implementing the bandanna or headband to create a look that will cover up colour.
Stripping hair colour should only be sought after a well experienced cosmetologist, doing a self strip could cause severe damage to hair and skin.
