Yes mine is nearly as long as yours Strawbs. Whole process took about an hour. You wash your hair with a clarifying shampoo, she blow dries. Then she paints on the stuff onto your dried hair, leave for twenty minutes, rinse again, then finally it is blow-dried again and gone over with flat irons to lock the stuff in. You can't wash or tie up your hair for 3 or 4 days after and it gets pretty greasy in this time. ClareC. I still blowdry my hair as normal (rough drying) and it doesn't need going over with straightening irons unless i'm going on a night out and want it poker straight. I've found my hair is more volumised but some others I know have said the opposite. The downside (IMO, a small price to pay), I find that I have to wash my hair more often now, but maybe that's because I'm constantly running my fingers through it.
