My daughter had a Japanese straightening perm a few days ago. She has 4c coil curls hair and has I was worried if the treatment worked. The process took 4.5 hours and my daughter’s hair is completely sleek, glossy and frizz free! She is so happy with it. Veda was amazing and trimmed the uneven strands of hair. We will definitely be back in 6 months for a root touch up.
