Im a mum of 5 and dont have time to do much to my long hair. My hair used to be thin but now it gets frizzy. I love this for putting on straight after a wash when wet or when ive dried it, i smooth some through the middle and ends. It makes me look like ive actually dried my hair with a dryer etc. wonderful goo.
