Questions on Relaxing my Hair?

Relaxers are horrible:( they fry your hair and damage it severely. If I were you I would go for a Brazilian Blowout. It is a form of a relaxer but its natural so it doesn't damage hair at all. It keeps hair healthy while giving it the permanent straight hair. The only downside is that it costs around 300 dollars. But its worth it and a regular relaxer sometimes costs more. But if you want a relaxer anyway, then yes you can get it wet, you can do sports, and it lasts usually about 2-5 months. I really don't recommend it though but you can give it a try:) best of luck:)
