And the thing is, neither do I. Ive got poker-straight hair and while it has plenty of flaws (believe me, plenty), frizz isnt one of them. Within ten minutes of listening to their woes, Im on the phone to George Northwood at Daniel Hersheson, Mayfair and streaming his advice directly to the girls. Heres a summary.
Dont use an umbrella. Its the moisture in the air that causes fizz (by returning hair to its natural pre-styled state) and under your umbrella can become a little hotbed of humidity.
Do wear a hat. Keep a small hat such as a beanie in your bag and if it starts raining, throw your hair in to a casual bun then throw on the hat. It prevents moisture getting at your hair.
Dont part your hair. If youre trying your hair back, beware of doing it on a parting as they can go really frizzy, not to mention make hair look flat. Instead, use your fingers to move hair back over the crown and in to a low ponytail or bun, then run a little smoothing serum all over.
Dont blow-dry your hair. Work some curl-calming product like Kerastase Oleo Curl Cream, £17.50, through your hair then rough dry till its about 70 per cent there. Loosely tie it back in to a bun, then once you get to the office, let hair down and scrunch it through. Itll dry with much less frizz.
Do mix your products. If you have an important meeting/hot date and have to blow dry, work a mixture of smoothing serum and Kerastases new Nectar Thermique, £17.50, through damp hair first. Nectar Thermique seals extra moisture into the hair so external moisture doesnt penetrate as much and cant do as much damage as a result. If you dont like serum, try mixing it with a little Shu Uemura White Tea Polishing Milk, £19.50, instead. Products will never prevent frizz completely but the right ones can seriously help.
And a final dont from me: despair. As George points out, the kind of hair that goes frizzy when its wet is the kind of hair that dries bigger, better and with more structure and holds its shape for longer. Hair that can look seriously amazing, in other words.
Frizzy hair? You lucky thing.
