OK in my younger years i wore a lot of weaves , glued in and sewn-in , this caused the nape the thin out and it has never grown back fully. Do you think the pictures show permanent loss? does anyone think Mega Tek will help? The rest of my hair is basically healthy relaxed, and is almost BSL. I have tried Profective regrowth serum last year and noticed a little growth but not much. ? Any other suggestions would be most welcome.
