Brilliant size for travelling only shampoo I use 

I can’t justify using this as an everyday shampoo, however it is a must for the 3 washes after box dying my hair blonde 

I have been using this shampoo since I discovered it, will not switch to any other shampoo.

Really good for reducing and getting rid of build up, and leaves my scalp feeling fresh. 

olaplex is my favourite shampoo (wouldn't recommend the conditioner but everything else is good!), really leaves my hair feeling clean i do have to knock off a star as its very drying on the scalp so if you already have dry skin or dandruff it can worsen that, i combat it by using a scalp serum
