Hair straightener help

I make a hair straightener formula with the following
5% lanette O 
5% lanette 16
5% dehyquart A 
5% petrolatum ( I use Vaseline instead of it) 
2% paraffine oil
1.5% NaOH 
I don't agree with this anywhy because it dry the hair after using it 
How can I improve this formula to be good and make the hair more moisture and more straightener 
## the formula make the hair straightener about 80% and 0% moisture
