I would generally classify fine hair as hair that is a little on the sparser side that needs encouragement to get extra volume. I would recommend BALANCING SHAMPOO as it is a lighter shampoo. If you have lots of bleach in the hair and the hair still feels dry, you might like to use HYDRATING SHAMPOO once a month, or you could leave TREATMENT CONDITIONER on the hair for a few minutes while in the shower.
There is a misconception that conditioner will weigh fine hair down, which is completely untrue. It is vital to use a TREATMENT CONDITIONER on the mid lengths - ends AND the roots of the hair to nourish and hydrate the hair and the scalp, which is important for healthy hair growth. If the hair feels that it is 'heavy' I find people have not washed the shampoo and conditioner out properly, so give the hair and extra good rinse before applying the next product which is why we recommend washing the hair twice, you will use less product in the end as you will get a better result and need to wash the hair less.
So wash the hair 2x with BALANCING SHAMPOO and apply TREATMENT CONDITIONER to the mids and ends, massage into the roots. Rinse well.
