How long should I give a new shampoo?
Around a month. Hair and scalp take a few weeks to settle after a change, so judging it after a couple of washes is not a fair test.
Can I stop washing my hair so often?
Most people can, though it takes a few weeks for the scalp to adjust. Stretching the gap gradually works better than stopping abruptly.
Do I need a separate conditioner?
If your hair is anything other than very short or very oily, yes – the ends benefit from it even when the scalp does not.
Are the scents the same across shampoo and conditioner?
Yes, the range runs the same scents through both, so they can be bought as a pair without clashing.
