I am 60 and have suffered thinning hair and lost patches also have frontal alepecia treat, which is hair loss all around the front hairline and eye brows, I use caffeine shampoo which has helped with the thinning of the hair as I had thick hair luckily but just a few hairs for brows so eye pencil for them, unfortunately it is part of the ageing process, and the worst thing, (naturally) is we worry about it and that doesn't help, just wish the whiskas on my chin would stop growing, better to have thin hair then not at all, sure you are all lovely whatever your hair type.
