The ombre

Hopefully, at some point, one of my lovely lady clients will let me do this on them. It may seem like just a trend, but personally I think if you match your roots close enough, it can be a nice looking low maintenance color/style. Low maintenance color choices like peekaboo highlights and half head color (different color from the occipital bone down) are popular for a good reason. They can grow out and look good for a long time. Of course it's only low maintenance if you're not going gray. I guarantee all the celebs getting this style are gray, but are trying to fool people into thinking their roots are growing in dark.( which makes it a high maintenance hair color after all) :-)
