Redken Cerafill Re-Densifying Treatment 90ml is an intensive leave-on scalp treatment formulated to help address the appearance of thinning hair. Built around the patented molecule Stemoxydine — a key Cerafill innovation — the formula targets the scalp environment to support the look of fuller, denser hair density over time.
About Redken Cerafill
Redken is an American professional haircare brand founded in 1960 in New York and now part of the L'Oréal group. Cerafill is Redken's dedicated line for the appearance of hair thinning and loss, developed with input from haircare scientists and salon professionals. The range is split into two tiers — Defy for the earliest stages of thinning, and Retaliate for clients with more visible loss — with this Re-Densifying treatment sitting in the more intensive part of the line-up.
Key actives
- 5% Stemoxydine: a patented molecule designed to help create a more favourable environment for hair growth by supporting hair bulbs that are in a resting phase.
- Filloxane: a polymer that coats and visibly thickens each hair strand for a fuller-looking head of hair.
- Ceramide R: helps reinforce the hair fibre and reduce breakage.
- SP-94: a scalp-nourishing component.
- Zinc PCA: supports a healthy scalp environment (in associated Cerafill products).

Who it's for
Cerafill Re-Densifying Treatment is designed for anyone — men or women — concerned about visible hair thinning. It is best used as part of a consistent daily routine and works well alongside the wider Cerafill shampoo, conditioner and daily scalp treatments. Talk to a professional stylist or trichologist if hair loss is rapid or unexpected, as underlying medical causes may need to be addressed.
How to use
- Wash the hair with the matching Cerafill shampoo and conditioner; gently towel-dry the scalp until just damp.
- Section the hair to expose the scalp.
- Apply the treatment directly onto the scalp using the supplied applicator, focusing on areas of visible thinning.
- Massage gently with the fingertips for one to two minutes.
