I am inept at doing my own hair so need a very basic step by step guide, if anyone with skills can advise 😊 I've a do between Christmas and New year but can't get a blow dry appointment nearby. I'm guessing I need, at a minimum, mousse and a big round brush and to work out how to hold the hairdryer at the same time as the brush. I'm tempted to invest in the revlon one step but think the barrell might be too big?
