Want extra heat protection? The Heat Styling Primer complements this fortifying Cream perfectly: use it on damp hair like the fortifying Cream, and it also protects during blow-drying or styling.

Your hair feels noticeably stronger and breaks less when combing. This is largely thanks to the Intra-Cylane™ molecule, which forms a network inside the hair fibre. This strengthens your hair from within, not just smoothing the surface.

Bamboo extract supports this effect by smoothing the hair’s outer layer, adding shine and reducing combing resistance. For weakened or damaged hair prone to breakage, this is exactly what you need. You can confidently include Biolage Intra-Cylane™ Fortifying Cream in your regular hair care routine.

Yes, Biolage FiberStrong Intra-Cylane™ Fortifying Cream is specially developed for hair weakened by chemical treatments. Bleaching makes hair fibre more fragile, which you notice when combing or blow-drying.

The cream helps reduce breakage. It forms a protective layer around the hair and strengthens the fibre from within. If you bleach or colour your hair regularly and notice breakage, this is a natural choice. Many wonder if biolage Fiberstrong is good for bleached hair: the answer is yes, this line is designed for that hair type.

Yes, the cream is suitable for daily use. However, occasionally use a clarifying shampoo to prevent buildup.

The cream contains Silicones and conditioning agents that can accumulate over time, especially if your hair is fine or quickly becomes greasy. If you use it daily, wash once a week with a shampoo that cleanses well. This keeps your hair light and fresh, while the cream continues to work.

Biolage Intra-Cylane™ Fortifying Cream is a leave-in cream: you do not rinse it out. A mask is used in the shower, left on for a short time, then rinsed out.

A mask works more intenSiively during application, but once rinsed, most of the protective effect is gone. The fortifying Cream stays in your hair all day, continuously protecting and strengthening. Want to combine both? Use the mask as a weekly treatment and the cream as daily support. To find suitable products, check the Biolage collection.

Biolage FiberStrong Intra-Cylane™ Fortifying Cream stands out from many other leave-ins by not only smoothing the outer hair but also strengthening the fibre itself via the Intra-Cylane™ molecule. Alternatives like Kérastase ReSistance Ciment Thermique also provide strengthening but focus more on heat protection and are usually pricier. If you're looking for a professional leave-in cream for fragile hair without the high cost of a heat protector, the Fiberstrong cream is a great choice.

Do you have very fine hair that goes flat quickly? This cream might feel heavy due to Silicones. In that case, consider a lighter leave-in. But for normal to thicker hair that is damaged or fragile, this product makes a real difference.
