Excellent product
OLAPLEX No. 4C Clarifying Shampoo delivers a deep, satisfying cleanse without stripping my hair ir drying it out. It removes product buildup and excess oil while still keeping it feeling surprisingly soft. The lather is rich, and a little goes a long way..

Removes build up
Olaplex No. 4C is a brilliant clarifying shampoo that leaves my hair feeling genuinely clean without stripping or drying it out. It removes buildup, product residue and hard water minerals so well, and my hair feels lighter, softer and shinier after every wash. Perfect for a weekly reset and works great before treatments too.

Removes build up without stripping
This is one of the better clarifying shampoos I have tried.
When my hair feels weighed down by product buildup or oil, it leaves strands feeling clean without stripping, however, because it’s designed to remove buildup, it can be a bit strong for daily use, so I have opted for once a week. I found that using it once every worked best to maintain balance without over-drying. I follow up with a hydrating shampoo a rich conditioner or mask.

Soft bouncy hair
My hair type is oily and I also have thick long hair which can get dense and matted if the oil builds up, I love a good clarifying shampoo which leaves my hair bouncy and volumised and this does exactly that. Best thing is it’s not overly cleansing and doesn’t rip out the moisture from my hair either, I love it! Only thing is it’s pricey but a great shampoo for healthy hair with a great finish!

Love this product!
This was the first Olaplex product I used. I had never used a clarifying shampoo before and my hair really needed it. This made my hair feel so clean!
