Flying Machine — jeans damaged even on soft washing

Address:

New Delhi, Delhi, 110034

I bought three jeans on washing hard two gets damaged so i think it should be washed gently as i like it comfy while wearing.

I again bought 2 pairs regular fit jeans from bindals situated in delhi.
I washed them about a month later after buying & i wash it very gently but it loses its charm again.

I like the comfyness but it is of no means if it loses its color. Please tell me what to do as i am hygienic so not washing my clothes is not possible for me.
