Depending on the condition of the hair and scalp, select 3 necessary phytoessences (the correct ratio is 3 phytoessences per 1 bottle of Base Treatment Shampoo pH 5.5, 250 ml).
Open the bottle of Base Treatment Shampoo pH 5.5 (250 ml).
Open the ampoules with phytoessences (for safety, you may use a cotton pad). Make sure that no glass fragments remain on the ampoules!
Add the contents of the ampoules into the Base Treatment Shampoo bottle and close the cap.
Shake the bottle well to mix thoroughly.
