Really great product. I used these to grow my hair out a few years ago. I cut my hair and bought these again to grow my hair back out this year. Went ear length to the middle of my back in 3 months. Ive also been growing my nails. No more fake nails. I just put an overlay on my real nails...and they're amazing. Shiny thick hair. And long strong nails!! My skin health has improved as well.
