This hair treatment for curly, coily hair is enriched with Amino Serum & Jojoba Oil, which is known to strengthen from within and prevent split ends. Our Amino Curl Repair range* with Bio-Protein Care technology is designed to regenerate hair strength and refill it with 1 trillion strength protein builders with every wash. This breakthrough system is backed by 10 years of research-reducing signs of damage and revealing long-lasting curls.To use, first apply the Dove Amino Curl Repair Shampoo and Conditioner, then apply this conditioning hair mask generously into damp hair from mid-length to ends and massage upwards. Let the rich formula work for 3-4 minutes and then rinse. Use once a week or more if your hair needs extra repair.
