Totally get what you mean! I used to feel the same way until I started using a mask every week consistently. Also, using a good leave-in conditioner after the mask has helped me maintain the softness for longer.
I’ve been using it for 3 months and haven’t had any side effects so far. I think the natural ingredients help avoid those issues. But, like always, it’s a good idea to check with a doctor first if you’re worried.
