I'm going on summer holiday filled with sun, sea and sand. The worst enemies of my hair!!!! Now I know I sould use a UV protective hair product, but I have quite flat and damaged hair thats very veerryyyy straight. So with out product and volume it looks limp and dry. Can anyone reccomend either a hair sun product that has some styling product in it or one thats conditions (so I put it on and put my hair in a bun)? Thanks!
