Amla really does counteract the loosening effect quite well. The last time I did a full head henna, the curls actually felt tighter than before I did the henna treatment. My hair actually felt a little shorter to me after I finished.
It is just a matter of tweaking the amla to the amount that is needed for your desired results.
