Made for normal to dry hair, and especially for hair that feels stressed, rough or hard to manage. Cynos describes it as a shampoo that nourishes dry, stressed hair. It is a salon-brand product for everyday use at home, and the litre size is a good fit for families or for anyone who washes often.

It is a straightforward, good-value way to wash dry hair without leaving it squeaky and rough. The cleansing base gets hair properly clean, while the cationic conditioners and dimethicone settle on the hair as you rinse, so it combs through more easily and feels softer even before conditioner. Paired with CRP Conditioning Balm it makes a simple two-step routine for dry, stressed hair.

• Wet hair thoroughly.
• Apply and lather with a gentle massaging motion from root to tip.
• Rinse well, and repeat if needed.
• Follow with Cynos CRP Conditioning Balm.
• For external use only. If it gets in the eyes, rinse immediately with water.

Pros: rich lather and a thorough clean; the conditioning polymers and dimethicone leave dry hair softer and less tangled; the 1000 ml pump bottle costs far less per wash than retail sizes.

Cons: it contains sulfates, so it is not the right choice for anyone avoiding them; it includes methylisothiazolinone and fragrance, which some sensitive scalps react to; it is a basic hydrating shampoo rather than a repair or bond-building treatment.
