Noticing baldness please help!

I’ve always had lots of hair. Loose curls now. I Stopped perming my hair straight in 2002. All I do is go to the Dominicans and wash and set. (I am Dominican descent) My hair is down my back. I cut my own ends now, and have been doing so for over a year (people get Sizzors happy!). I have no color no chemicals at all. My SO wants me to have my hair curly, he loves the “erotic” sexy look lol well I can’t cause having it curly makes my balding edges show more then when I blow dry straight.

Well on to the bad part. I’ve noticed my edges are more and more thin. Now balding. It has never been on top by my parting. And now it is. I’m so upset cause I don’t know if I should stop the salon twice a month or go back to trying to wash and fix my own hair. I drink daily biotin 10k mg tablets. Since February. My hair does grow in length but not in thickness. I want to die my hair or cut it all off at this point. Even my bangs don’t grow full anymore. Anything advice or home remedies please share.

Thinking of investing in the following products.

I keep hearing that surgery makes hair fall out and I had surgery in the beginning of the year. But I won’t lie, I’ve been having thing edges for over 10 years now. I just know how to comb my hair to hide it. I’ve tried everything. Cinnamon oils, all kinds of drops. I stopped the hot irons. And don’t tie my hair back tight anymore. I’m at the verge of cutting off all my hair and buying an expensive front lace wig.
