After swimming in a chlorine treated pool we recommend hair care products which moisturise the hair, such as LINDENGLOSS or MALLOWSMOOTH Shampoo and Conditioner. Also use any Leave-in & Special Care moisturising product or a combination of products. 

It's also important that you shampoo correctly with Less is More.

How to use Less is More SHAMPOO

Make sure hair is thoroughly wet, with only an almond size amount of product spread between fingertips and work into scalp, rinse and repeat. You’ll find SHAMPOO lathers even more on the second application to move beyond scalp and onto hair length.
