Hair loss and how to get it back!

So this one is embarrassing. I know in the big scheme of things it's not major, but I'm really hoping it's fixable.

I have always only had two physical features about myself that I like. My eyes. And my hair. It's always been really thick, is naturally wavy and I can style it however I want. Over probably the last ten years it started coming out during a hair wash but would seem just as thick. However over the last six months I've noticed it's not growing back. Where I would take an extra-large bobble to hold all my hair in a pony tail I now only need a small bobble. And then, a few months ago, I saw a photograph of me and I could see where I am thinning on top. I mean seriously, patches going bald!!

Gutted.

Of course I then Google to find out what the hell is going on. Not the menopause, that's long gone. I don't feel ill so hopefully not that. But I did read something very interesting. Apparently if you lose a lot of weight over a relatively short period your hair follicles go into hibernation! So I'm obviously hoping for the latter!

But I'm not taking any chances.

My hairdresser suggested Plantar 36 so I'm giving that a go. No huge change yet. I mean, come on, I've used it 3 times now, where's my miracle cure???

But I have also met this lady on Instagram, MONAT@modern_nature_hair , whose products look amazing. Great :) Except they don't ship to the UK. Not great. Oh yes, WAIT ....... I have 2 sons living in America so thinking of getting it delivered to them - where there's a will there's a way :)
