@Angela80 hi, have you tried the curacen placenta and mesoing it? The curacen is better for Meso and I find it more versatile. I can use it everywhere, face, scalp, hands, body. I have had my derm do prf around my hairline and I Meso the curacen about every 4 weeks (one month I Meso curacen, next month i have derm do prf) and it has made an amazing difference my receding hairline. I don’t do it all over my head, but i know a few ladies here who do Meso their scalp. I find it much easier than MN and I feel the product gets in where I need it. Good lucK!!! It’s definitely a challenge finding a solution that isn’t $$$$ and works. Also, if you have Curanex on hand, try mesoing that - it’s very inexpensive and I’ve used that when I run out of Curacen and it seems to work well too. The studies I have read rank prf best, placenta second, and pdrn third, but they all give good results.
