My hair is wavy in nature ..

Unfortunately in the days when I tried to straighten my hair the only options were to go to the hairdresser or continually put it in large hair rollers. These days I just accept that I have curly hair and live with it and I feel so much happier about that fact when I see friends who pay a fortune to get what I got naturally. :)

I only straighten my hair with an iron and use a good hair serum.

the best way to straighten hair according to me is go to parlour.these days the parlours are giving guarantee for hair straightening.otherwise rollers can be used.

You can't straighten your hair without using either chemicals or heat. If you're going to opt for the less damaging one I'd say go for the heat.

thr no way of straigtening hair wohtout chmeicals or heat.. but wavy hair are in fashion so can try this for wavy hai ro look good f you want to coax more curl, use your fingers to detangle instead of a comb. Are you wondering about styling lotions that promise to straighten? I was dubious about them, but then decided to try them while on vacation. I was amazed at how well they work. However, if you prefer to smooth out the waves, I would suggest using your blow dryer. Here are some steps to follow. How To Blow Dry Things You Need: -a blow dryer that offers between 1200 and 1500 watts and is light enough to hold easily -sectioning clips -straightening balm if hair has curl -hairspray that will hold without -leaving hair crunchy -large round brush Step-by-Step Instructions Apply your favorite straightening balm if hair has unwanted curl or wave. Gently detangle hair, create part and allow to 90% air dry. Horizontally section hair leaving a section free. Pull up remainder of hair and pin in place with sectioning clips on top of head. Divide the free hair into 4 manageable sections depending on thickness and length. Hold dryer in one hand, brush in the other. Choose one of the 4 sections and move the brush and the blow-dryer vertically, directing airflow down the hair shaft. Continue from section to section of free hair until all the sections are dry and smooth. Remove clips, horizontally section off more hair and allow this new section to fall loose. Re-clip damp hair on top of head continue the drying steps as described above until all of the hair is completely dry. Style with a brush to coax desired movement and then spray to hold.

if it's naturally wavy, i don't think it's possible that you could have it straightened without using any chemicals or heat treatment. but, perhaps, you could try, combing it at night.
