sodium lauryl sulfate and silicone free shampoo

[snowie]

I just started using a sodium lauryl sulfate and silicone free shampoo i always had very frizzy and wild hair and my scalp itched like crazy, my hair actually looked like a mess, it looked very dry because of the frizz.
After i change to the sodium lauryl sulfate and silicone free shampoo all these problem has stoped !!
I still have a shitty hairline, but im starting to wonder if my scalp is allergic to sodium lauryl sulfate and silicone, so what is why it all stoped.

I just wanted to share this if any others have the same problem

Sorry for the bad english
