I have natural curly hair.due to many years of coloring,and flat irons my hair is dull,and lifeless.how can I get my curls back?or can I

If you cease coloring it, and don't damage it with flat irons, it will grow out to whatever it is naturally -- now. Will it be curly? Maybe, maybe not.

You have to remember, as we age, our hair changes and not for the best. Five years ago I had a thick head of hair that when air dried, I had kinky ringlets. Now at the age of 62, my hair is very thin on top and straight as a pin. Breaks my heart but what can you do?
