I'm shedding like a labrador lately, everywhere I've been there's hair, when I wash it there's a ridiculous amount in the plughole and tonnes on the brush when I've blow dried it. I can tell by my ponytail that there's thinning but it's not really noticeable to others yet, apart from when my clothes are covered in it, but if it carries on the way it has been doing, I'm going to get some obvious thinning patches.
What can I do/take/eat/treat with to ensure I've still got hair in a year's time
