Daisy22- I appreciate your suggestion but I am avoiding steroids as long as I can. I've been steroid free for years now, I used to get the Kenalog-40 corticosteroid injection once a year for my Allergic Contact Eczema. It helped dramatically for 10 months and then I would tough it out until the years end. The problem was the side effect of major hair loss beginning about 2 months after the injection and lasting about 3 months. It would regrown, but never to longer than 3 inches around the hairline. I'm eczema free now and no longer need the shots because of contact and dietary changes.
I want you to be aware that Kenalog is a potent corticosteroid, dramatically more potent than cortisone. That's why my dermatologist only wanted to give it once a year. Too often can damage your internal organs.
Still if this Platelet Rich Plasma doesn't help I may have no alternative and go back to having my hair fall out after injections.
