I have to confess an interest here: my partner is a hairdresser - you'll see his banner ad on the homepage,
www.allabouthairandbeauty.com.
Anyway - I was previously a client of his, and went to see him when I had lost a great deal of hair through hypothyroidism. Of course I'm hopelessly biased, but he was brilliant -just quietly and discreetly cut in a series of layers to maximise volume. He's very big on what he calls 'personal consultation before you pick up the scissors', so if you wanted to call him I think you'd find him sympathetic.
His name's Richard if you want to look him up on the site.
