I have supplemented with the L’Oréal Paris Growth Booster Serum in the same series as the shampoo and conditioner, and I think it’s a really good finishing product in the routine. The serum is light in consistency and doesn’t feel greasy or sticky on the scalp, which can otherwise be a risk with leave-in products. It’s easy to apply thanks to the dropper, and it absorbs quickly without leaving any residue. My thin, fine hair feels stronger and fuller, and together with the shampoo and conditioner, it feels like the whole series makes a noticeable difference. The hair feels healthier, easier to style, and more resilient. I would have wished for a bit more moisture in the lengths, but as a scalp treatment, it works very well. A serum that really enhances the effect of the other products in the series.
The review was conducted on behalf of Smartson – the test pilot was allowed to try the product for free.
