What shampoo does everyone take on holiday? I've been taking Boots sun, swim & gym for the last 10-15 years or so, since an unfortunate green hair incident (dyed hair plus cloriene doesn't mix!). This has been out of stock for aaaaages so I'm looking for something that'll do the job, nothing too expensive as I'll be sharing with the dcs and dp who won't respect a hefty price tag!
