Olaplex No.4P Blonde Enhancer Toning Shampoo 250ml

Great Product

It does what it's suppose to do....reduce brassiness, and it leaves hair so soft and shiny. It does make white hair very vibrant which I don't mind. Highly recommend for thick hair.

Holy grail!

I have long, platinum blonde hair and have used a range of toning shampoos and conditioners over the years. I’ve recently invested in a few Olaplex products, this being one. It’s absolutely beautiful on the hair, not drying at all. I leave it in for 4-5 minutes and even though it looks purple while it’s on, it rinses to the most stunning cool blonde, no yellow, and just ever so subtle hints of pretty lilac. Superb! Very happy.
