Where abouts do you keep your hair straightener? As it may be because its cold or has condensation inside it. This may sound funny but you actually shouldnt keep your GHD in the bathroom cause they can get cold and dont like it, or if u want to keep it in the bathroom then wrap it in a towel. This may fix the problem. If not then call GHD and you may be able to get a replacement. Hope this helps :)
I'm absolutely in love with my GHD.I will never buy another brand again. It heats up super quick, glides through the hair like silk and takes alot less time as with previous straightners i've had to go over the same strand a few times and it left my hair frizzy/flyaway and meant i had to use products to smooth it down! I dont really need to use any products except hot iron spray or cream protectant and a tiny amount of serum afterwards. The GHD also curls my hair perfectly, now that ive mastered the technique ;-)
I worked in the hair industry for a while so I've used a lot of high end flat irons and I got to say, this one did not impress me at all. I'd never used a GHD before this btw (none of the stylists I know have one) but I ended up ordering the GHD classic styler--which btw seems to be the same as the "IV styler"--instead of the CHI Turbo due to the fact that at the time, the GHD was on sale and basically the same price yet it offered more versatility (the turbo has a velvet cover so you can't use it to curl).
"About to re-purchase!My GHD has lasted going on 9 years (literally through THICK & THIN).* Nice firm/gliding grip/No tug/pull of the hair. Opens and closes gracefully (doesn't sound like it needs WD40 LOL. EASILLY CLEANS. NO Lines are left on the hair strand , easy for clients to use with confidance as well. Doesn't project a burning steam with product close to scalp. Bevels well. Works great as a waver..... this is a Universal Flat Iron for all ethnicities!"
