my hair is curly in nature and i have a lot of difficulty to maintain it,and on top of that it is my brothers wedding that is coming up next week during which i have told everybody that i will be straightening my hair and there is a lot of buzz about it as my family members know that how difficult can it get to get my hair straight.but now it is only two days left and i have no idea to straighten my hair. so my friend told me to try Chemically Straightening for my hair. What is the way to chemically Chemically Straighten my hair?will these chemicals in turn damage my hair badly and if i want to prevent it how long can i don the Chemically Straightened Hair style and then wash my hair?
