Details.
Designed to smooth, straighten and reduce frizz by infusing hair with keratin. It tames frizz, smooths curls or waves, adds shine and softness, and makes hair more manageable. Results typically last 2 to 4 months, depending on hair type, product used and aftercare. Sulphate-free shampoo and avoiding or minimising saltwater and chlorine exposure can help extend the results.
