It amplifies the hair texture, strengthening the hair whilst protecting hair from damage and breakage, leaving scalp refreshed and hair with a natural, radiant and healthy shine. Achieve denser-looking hair with the NIOXIN 3-part System 1 Scalp Therapy Revitalising Conditioner for Natural Hair with Light Thinning. Nioxin System 2 Scalp Revitaliser has been expertly formulated to boost hair growth, particularly for those who are experiencing thinning hair due to menopause - a common side effect. The revitalising treatment promotes thicker and stronger looking hair, whilst maintaining and encouraging hair growth and scalp stimulation.
