Welcome. But the palm rolling is a bad call. It does either 1 of 2 things. It will either do nothing. If you have been doing it for 7 months, then you should see that having to redo it all the time shows that each individual time didn't do anything. In 7 months, if you see any progress, it's not from the palm rolling. It's from time.
Or it will irrevocably damage your roots and locks. I only did it for a few weeks and 6 years later and still worried about 5 of them falling off because of their own weight. Palm rolling tends to rip hairs out, but they get sucked into the body of the lock. So now you have a locks with x# of hairs that add weight to your lock, but don't give it any support to your scalp. Doing this over and over will lead to a thicker lock with a super thin root. I posted a video on my page about what it did to my locks after just a few sessions. Check it out. It'll definitely make you stop, if my description didn't already
