What do you use?
I have been using a GHD smoother, which i do like, but wondering if anyone had any super dooper recs that i should try out next. only stipulation is that they must sell it on hqhair as my brother got me a gift card from them for christmas.
i don't actually know if serum is the right term - i mean the product you put on while your hair is still wet before drying / straightening. smoothing moisturising stuff. is that serum? ?
