For over 20 years I've washed my (fine, dullish, highlighted) bob every day because by Day 2 it's greasy and flat. The ends were getting so bad- dry and fluffy- that I had to have it cut again recently. Every hair stylist says I need to try and wash it every three days to improve quality but I seriously look dreadful. Thinking of trying to 'train' my hair whilst I'm not at work over the summer. Is it possible? I'd love it to look healthy and SHINY but it's always dull.
