The litre-size System 4 conditioner for coloured hair that looks thin
Nioxin System 4 Conditioner is a conditioner from the Nioxin System 4 range, made for chemically treated or coloured hair that looks noticeably thinner. It comes in a 1 litre bottle, the large format often used in salons and by families who go through a lot of product. It is the conditioning step of the System 4 routine, used after the matching cleansing shampoo.
How it works
A conditioner that you work through the lengths after shampooing, then rinse. Nioxin develops it for hair that is coloured and fine at once, so it softens the lengths without a heavy film that would flatten the roots.
Who it suits
- Coloured or bleached hair that looks thinner
- People following the full Nioxin System 4 routine
- Salons and busy households that want a litre bottle
- Hair that feels dry and tangles after colouring
Worth knowing before you buy: System 4 is matched to coloured hair with progressed thinning. If your hair is natural and untreated, System 2 is the matching range. The conditioner helps hair look fuller and feel softer, and it does not treat a medical cause of hair loss.
