I have fine hair (although still quite a bit of it), but I find loads comes out in the brush whenever I brush it. I try to be as gentle as possible and use a decent quality brush, but still happens. Am mid-40s and have nasty visions of thinning menopausal hair - not a look I am keen to channel….. Anyone have any advice? Are there any shampoos that help with this? Saw some Pantene one claiming to strengthen hair advertised somewhere, but have no idea whether claims are utter baloney. TIA .
