Olaplex No.4P Blonde Enhancer toning purple shampoo.

Lovely product. Does the job of making your blonde lighter instantly. I do love this product, just I’m not using it much anymore. I would say it’s pretty heavy so there is still a lot of product in there. I probably used it 3 times but didn’t use much of it. I will drop the price as I don’t know how much is in it exactly, but when I pick it up it feels pretty full.
