I'm not a hair geek but I like to look at all posts because I'm nosey hehe
Anyway I felt like i had to reply to this...
I used to have ghd's but after 3 years they broke & I couldn't afford to buy a new pair straight away.. My friend mentioned 'nicky clarke - desire' so I purchased some from boots whilst they were on offer for £65, they are fabulous! I'd say in my honest opinion that they are far better than ghd, my hair stays straight for ages with them!
I have thick frizzy hair too.. I look like her out of the ring before I've straightened lol - but seriously they do a perfect job, hth x
