I have been a hairstylist for 18 years and I can tell you that in 4 weeks the average regrowth is a half inch. Sometimes a bit more, sometimes a bit less depending on your rate of growth. That means that in 2 weeks you will have approximately a 1/4 inch root. If you color your hair substantially darker than your natural color/grey the grey hair or natural color will be much more noticeable as well.
