Best One I’ve Tried!
I’ve been using Olaplex Blonde Enhancement for a few weeks, and I’m so impressed! It has brightened my blonde hair, eliminating brassiness and leaving a vibrant, cool tone. My hair feels stronger, softer, and much healthier with less breakage doesn’t feel dry. It’s easy to use and doesn’t weigh my hair down. The only downside is the price, but it’s worth it for the results. Highly recommend for anyone with blonde hair since it works pretty well.

This blonde enhancer purple toning shampoo will for sure will take out brassiness and warmth!
Nothing has ever worked for me and my daughter before this! Be careful to start with it because it will change the color of your hair! I have extra brassy ends so when I used this all over my hair the roots were a little cooler than needed. But it does wash out after a few washes so no worries.

Love this and understand why it comes highly recommended!
This is recommended by any professional stylist who is qualified to suggest it. I love this, but use a moisturizing shampoo like Moroccan Oil prior so it properly cleanses your scalp. Hair is left soft, the size is perfect, and it does not leak when you place it back. Lightweight and leaves your hair bright and full of shine and smelling great.

Worried about nail and cuticle staining.
I’ve used other olaplex before but this on has changed the color of my nails and cuticles. That has never happened before with previous products. You should know I have used many of their products.

It works perfectly
Effective toning / brass removal Many users see a noticeable reduction in brass / 2. Less staining / gentler feel it doesn’t stain fingers or scalp as badly as other purple shampoos. And even though the pigmentation is strong, it rinses cleanly 3. Adds softness / shine Beyond toning

De los mejores matizantes que he encontrado para mis mechas y canas, además de la hidratación que deja en el cabello. Sin duda, sigue siendo la línea para el cabello, favorita para mi.

It’s just as if I went for toning at the salon. Keep it for 2-3 mins for a usual wash or for 5 minutes for a toning effect to kick orange tones out. Better use tangle teaser or another brush because I still had some parts where it didn’t reach
