Swartzkopf can't save me! I tried the black bottle range.
I use Kerastase which is salon sold and pricey but works. Aveda used to be one of my favourites, you should try it as its natural and organic.
When I say it can lock together, I can literally plait it and it stays. It's not frizzy unless I brush it. But only underneath. I've got a right mane of hair which is so heavy it can give me a headache if I wear it up. Definitely it's a bit of hard work, I ride a bike too and the crash helmet/ wind don't help either!
