Just another wee discovery I've made in the past month regarding my thinning and flyaway hair. I used to have a full head of thick healthy black hair that has changed texture as I've gone grey. However, since developing hypothyroidism it's been so distressing to see it fall out, frizz up and resemble candy floss.
I've been using Philip Kingsley products specifically designed to address hair loss and frizz. I use body building shampoo and conditioner as well as the scalp stimulator. He also does a deep conditioning treatment that I use once a week. I sleep with it on under a shower cap. It has made a big difference already. If you buy online they send you lots of lovely samples. Go for the trial size as it can be expensive to buy if you end up not liking it.
Just google Philip Kingsley hair loss products. He has a clinic in Mayfair London but it will set you back £300 for a consultation. The products are enough to make a difference so might not be necessary unless you're not short of cash!
