I am an 24 year old Caucasian woman with naturally short and curly hair. I straighten my hair and dye it blonde and it is very slightly less than shoulder length. I want to naturally have long and straight hair (about 5 more inches of hair) as quickly as possible though, but I am only allergic to coconut oil, blueberries and peanuts. I am very healthy and have no health problems. What are my options?
