I am 41, and have just longer than jaw length mid brown hair. It's very fine, there are some long layers in it. It is kinky, rather than wavy or curly, so I straighten it.
Hairdresser was rough drying it today, and I liked it looking messy. He said to achieve that look, I should buy a salty sea beach type spray.
Any recommendations please, particularly for my hair type? I need to be able to buy it from my large local Boots.
