I've never used any products on my hair mainly because i hate the feel of my hair being weighed down. Now after having 3 kids my hair is thinner and lacking 'oomph' 
Can anyone recommend a good volumising product, for use with either hairdryer diffuser or BBH?
Also a product to make the most of my natural waves?
And something to help an updo stay up? 
I have thick hair below shoulder length with a natural wave if i helps.
Thanks
