It could be in shock from the shampoo but I know I accidentally used a cone and my hair was losing curl and not acting right. I was mystified until the conditioner was greasing up on my hair and then I remembered seeing that before and I shampooed with a sulfate poo and then just went back to my routine.
Whew I was so glad to figure that out! I hate that many bad hair days in a row.

Now if I shampoo after not doing it for a while with something harsh I'll get poofier hair but as soon as I DT my hair is back to normal.

I hope you figure it out soon!

If it smells good put it in your hair, if it tastes good spit it out!
