How do you reverse straightening done by a flat iron?

I have had extremely curly hair since I was a baby. I am 29 years old, about a year ago I started using a flat iron on my hair for the first time in my life. With in two months, using it about once or twice a week my hair lost 90% of it's curl. It's now at best wavy, and I have to straighten it just for it to look right. Does anyone know why this happened? I use a shine product and straightening syrum when I style. I miss my curly hair so bad! I have before and after pictures.

This was my hair end of Feb last year.

Try not to straighten your hair so much and dont use the products on it.How do you reverse straightening done by a flat iron?
Try to stop straightening your hair so often. It can really damage your hair.

Other than that, switch to a curly shampoo and conditioner, mine works fairly well (Herbal Essences) but I really like Pantene ProV too.



Good Luck ^^
