nope
the process that you did and the steps you went through are correct. You hair is behaiving as predicted with asian hair.
those chemical relaxer do not give a lasting results, but it does cut your ironing time a bit. Yes it sucks but that is just how it behaves. I used to apply relaxers every 2 weeks to keep my hair straight.
For the record I could apply relaxers to my hair up to 6 times, before I noticed any damages (dryness, frizziiness)
There was this one time where I fried my hair, I had it colored twice, relaxed 4 times, and bleached onced and then relaxed it again.
what i got was beyong damaged, it was irreplaceble (to the left, to the left  )
my hair was mushy like cooked pasta and was so fragile just a pinch could break it.
So if you stay away from bleach and avoid dyeing your hair, you will do just fine. Just remember to cut your hair every 2 months to get rid of the damaged ends.
One of the only but not sure way to have bone straight hair permanently is to do the rebonding/japanese straightning/ thermal reconditioning method.
It is the extreme method of chemically straightning your hair with the use of a hot iron with the thermostat set at 180 Celsius ( water boils at 100 Celsius)
Process is long, so you will be sitting in that chair for a long time. In america the process from what I heard is pretty darn expensive around $300 or more (i am not sure about recent prices, but my american friend told me it was really expensive). In asia you can get it done for a fraction of its price.
So keep on straightning and avoid burning.
