John Frieda ULTRAfiller+ Hair Density Scalp Serum 2 oz — Lightweight, Biotin & Peptide Volumizing Treatment for Fine Hair

This targeted 2 oz serum is designed to strengthen the scalp environment and reduce breakage for people with fine or thinning hair. Made to be used daily on wet or dry hair, the formula absorbs quickly without residue and pairs with John Frieda's ULTRAfiller+ shampoo, conditioner and thickening spray for a complete thickening routine.

How does the serum support fuller-looking hair?

The serum works at the scalp to fortify strands and cut down on breakage-related shedding. Its blend of biotin, peptides and caffeine aims to nourish the scalp surface while delivering lightweight conditioning to the hair base.

• Biotin and peptides support stronger-looking strands near the root.
• Caffeine delivers a refreshing sensation at application.
• Non-greasy delivery absorbs quickly, avoiding flatness.

When and how should I apply the scalp serum?

Apply directly to clean, wet or dry scalp once daily, focusing on areas that look finer. Gently massage the serum into the scalp with fingertips to distribute evenly; styling can follow immediately since the formula is lightweight.

• Use after shampooing and conditioning for best routine impact.
• Dispense a few drops along part lines or entire scalp, then massage in.
• Safe for daily use and compatible with styling products.

Will this serum make my hair oily or heavy?

No — the ULTRAfiller+ scalp serum is formulated to feel weightless on fine hair. It melts into the scalp without leaving a greasy film, so hair maintains natural movement and style hold.

• Lightweight texture avoids weighing down fine strands.
• Fast-absorbing finish reduces visible residue.
• Works well under leave-in styling and heat protectants.

How does this product fit into the ULTRAfiller+ system?

This serum is step three in a four-part approach: shampoo to plump, conditioner to strengthen, this serum to optimize the scalp environment, and a finishing spray to boost overall thickness. Together they create a consistent routine targeted at improving the appearance of density.

• Step 1: ULTRAfiller+ thickening shampoo for immediate visual plump.
• Step 2: ULTRAfiller+ conditioner to align and fortify strands.
• Step 3: This scalp serum for daily scalp care and lightweight fortification.
• Step 4: Finish with thickening spray for volume and heat protection.
