I'm new I just wanted to stop by and say "HI", I've been natural for about 3 years now. I THINK I have mostly 4a edges + nape with some frizzy/coarse (4b maybe) parts in the middle. I'm here looking for styling ideas and product recs

My biggest problem is that I have pretty severe Rheumatoid Arthritis (w/ multiple surgeries on both hands) which makes manipulating/styling my hair VERY difficult especially that coarse part in of all places the back! I also have problems with dryness in that area as well, just looking for advice support, etc..
