Will these fit Olay Professional X Advanced System set as a replacement head?

No they are for the Clarisonic brush only. You can find replacement heads for Olay system by adding Olay to your search criteria.

I have never used the Olay system or seen the back of it to know if it fits. This was made to fit in the Clarisonic mia, which is what I have. The bristles are strong maybe even a little rough on the skin.

I will be honest. When I purchased I was not sure if they would fit. These brush heads looked like mine so I took a chance. They are better than the brushes that came with my unit. If your brush is a single rotating head with a color coded band at the base I would bet they will fit.

Sorry - I do not know. These are the eSeries heads. We have (3) different Soniccare models, but all are just slightly different versions of the eSeries. These heads fit each of those models.

Yes, fit on mine; however, noticed that head needs to be turned & tightened again at times after use--not a problem.

Yes, they will fit. They are the same size/fit as the floss action heads, which fit the 8850. The Oral-B site for 8850 shows the fit too @ http://www.oralb.com/en-SG/products/pc8850/#brushheads-0 (I should clarify they call them Pro Bright there), but it's the same head.

it comes with adapters that will fit most power heads and lock-lines, you should be able to fit it on most any power head

You need the HQ8 Replacement Heads: http://www.amazon.com/Philips-Norelco-HQ8-Precision-Replacement/dp/B000068PBT/ref=sr_1_1?ie=UTF8&qid=1393070223&sr=8-1&keywords=hq8+norelco+replacement+heads

Don't know for sure but it comes with a 4 different adapters and I found one of the adapters that worked for me as I was told that replacement heads were no longer available for mine and I think this one will work for you

Sure will. If you should decide to get one of the new ones, they will not fit on your current setup.

Yes, these replacement heads fit the DAZ-7180 model. Thank you for your question!

I'm not sure. The included Phillips heads are not as small as the slot headed ones though. I've used these mostly for electronic stuff. My gut sense says no.

The info on the package reads "Compatible with P-HX-6013 Replacement Brush Heads". I think that narrows things down.

a quick google search will tell you that they will fit (please verify for yourself before purchasing). I'd recommend getting involved in a forum such as infinitiq50.org

I believe they are to mimic the clarisonic so if you can use clarisonic heads with the Olay pro x then you can use these.

Hello, These replacements are only for the ProResults Series not the E Series; two different replacement heads. Some of the products on Amazon will allow you to choose you series via a drop-down box so you may want to check if the particular seller/vendor you are looking at allows such an option. Thanks

They should fit but you should match the dimensions of your equipment with the specs.

NO, it is NOT compatible with Olay, sadly. Having to send my set back because the Gurin heads don't fit my Olay.
