I have a quick question on how chlorine affects natural hair. Iíve been fully natural for 6 years and always thought my hair was mostly 4a with some areas 4b/3c. However I went swimming the other day And didnít wash out the chlorine right away. I already know that chlorine will make any hair type dry and crunchy if not washed but when I woke up the next morning my curls were a lot tighter in diameter (4b or maybe even tighter!). Once I washed my hair my curls loosened up to the size Iím used to. I just wanted to know if this is normal?
