I regularly use both straighteners and curlers on my hair, as well as blow-drying it several times a week, so as you can see that's a lot of heat! My hair was becoming quite dry and damaged and my hairdresser recommended I try a heat protection spray on it.
Supersoft's spray is fabulous. It has a light, barely noticeable scent to it, and you only need a few sprays of it at a time so a bottle lasts well. I simply spray it in, comb through and then style as normal. It's a very lightweight spray and leaves no residue in the hair, therefore doesn't interfere with any other styling products such as sprays. My hair does indeed feel super soft after use and not sticky or weighed down.
I've been using this for around 2 months now, and there is no noticeable damage to my hair, and it's not feeling as dry as it used to, which are factors I'd have to give this product credit for.
