Had my hair done at the hairdressers. Before she blow dried my hair she put some product on and then proceeded to curl it with a large round brush. It came out with beautiful loose waves/curls. I should have asked her what product she put in my hair but didn't think. Went to blow dry my hair and the curl just will not take. Can anyone tell me what product she Is likely to have used. I haven't a clue what could hold a curl like that with a simple brush and blow dry. The curl lasted a few days. A recommendation would be great for a product like this and even a great brush. I just cant get it to work as my hair is pretty fine and looses its curl easily.
