Serioxyl FAQs


What is Serioxyl?

Serioxyl is a new range from L’Oréal Professionnel to create beautiful hair that looks thicker and denser.

What is the technology in Serioxyl?

Serioxyl contains Stemoxydin™, Neohesperidin™, Glucoboost™, Incell™ and Intra-cylane.

What’s the difference between the Aqua Mousse and the Thicker Hair serum?

You apply Aqua Mousse to the roots and apply Thicker Hair serum to the lengths and ends for thicker looking hair.

Can I combine the products with other products in the L’Oréal Professionnel range?

For the optimal thickening look we recommend that you use the whole Serioxyl range, but for a different or added effect then you can add other styling products. Ensure that the Thicker Hair serum is applied before applying any other products to your hair.

Can I use Serioxyl while pregnant?

The safety of our customers is of paramount importance and the most important factor behind our research and development. L’Oreal Professionnel Serioxyl is safe to use during pregnancy. However, if you have any concerns we suggest you consult your doctor. If you would like to explore this topic further, we suggest visiting the website for the Cosmetic, Toiletry and Perfumery Association. The CTPA provide the public with direct access to the Cosmetic Industry’s perspective and progress on common safety questions, as well as information on how products are regulated to ensure their safety and efficacy.

Can I use Serioxyl the same day as a colour service?

Serioxyl is not recommended to be used on the same day as a colour service. It is a deep cleansing service for the scalp where the product rinses out afterwards, leaving the hair wet. Serioxyl works perfectly as an in-between colour service.
