The hair forecast for the coming months range from disheveled long hairstyles to sophisticated volume that revisits beehives. This season is all about choice, says celebrity hairstylist Sam McKnight, who worked at some of the biggest runway shows, including those for Chanel, Mulberry, Prada, Vivienne Westwood and Fendi. “But whatever look you go for it relies on great hair that’s been well cared for.” That means before trying any look, to always use a pre-styling treatment to protect hair from heat damage and to keep hair hydrated.
