Hi
I have the same affliction! My husband tells me he loves my curly hair, but in the same breath calls me "pubic hair head" - very attractive. This hot, humid weather is torture.
I have spent years trying every product and technique on the market, with varying results, but nothing works at the moment.
The best solution I have come up with so far is to use Charles Worthington Results shampoo and conditioner - the orange one for moisture. I then use L'Oreal Tec styling gel before I blow dry. Use a big brush with open vents - mine is a Babyliss brush. Divide your hair into sections and use a clip to separate. Start with the sections underneath. Wind the hair over the brush and point the hairdryer down the hairshaft to smooth the cuticles. Always finish each section with a cool blast before moving on to the next bit. When it is all done, smooth over some Frizz-Ease serum, and give a spray with Frizz-Ease hairspray. I do have straighteners, and I dont find that they damage my hair anymore than using a hairdryer everyday. As long as you use a product to protect the hair, it should be fine. I always finish my blowdry with a quick straightening - only going over each section once.
Hope you have some luck, and the day isnt too humid. Enjoy yourself.
