Balayage is the hottest trend in hair at the moment, and to be quite honest it's not going any where. This soft and subtle highlight is so beautiful, but what makes it so amazing is the maintance.... Or should I say lack of. This technique is softer at the root, so there isn't a hard line of demarcation as the hair begins to grow out. What does this mean? Your traditional highlights require a 6-8 week retouch... Balayage is 8-12.
