# Quick summary A Who What Wear writer skeptical about adding collagen to her hair routine tried Gisou's Honey Gloss Collagen Drops ($25) and saw an immediate difference: more softness, visible shine, reduced flyaways, and enhanced curl bounce. She used the drops as a finishing oil after her regular routine and paired them with other Gisou honey-infused products.
# What the product did The drops acted as a lightweight finishing oil that didn't weigh curls down. They delivered hydration and gloss quickly, smoothed crown flyaways, and added spring and definition to curls. The writer credits both the hydrolyzed collagen and Gisou's signature Mirsalehi honey for the combined effect.
# How collagen works on hair Tina Mui, trichologist and cofounder of Aware Hair, clarifies the role of collagen in haircare: collagen is not the main structural protein of hair—hair fibers are primarily keratin. In cosmetics, collagen is usually hydrolyzed, meaning it's broken down into smaller peptides. Those peptides can deposit onto damaged or porous areas of the hair fiber and improve smoothness, softness, shine, and manageability.
# Who benefits most Gisou's collagen drops seem most useful for people whose hair is dry, rough, or made harder to manage by heat styling or everyday wear, and for those whose hair isn't heavily color-treated or chemically processed. For such hair types, hydrolyzed collagen can add conditioning without requiring an intensive repair regimen. If your hair is low-porosity and protein-sensitive, use collagen products sparingly to avoid protein overload.
# Product context and extra notes The writer used Gisou's drops in combination with other Gisou products like the Honey Gloss Ceramide Therapy Hydrating Shampoo and the Hydrating Hair Mask, noting that the combination boosted detangling, hydration, and gloss. The writer found the honey-collagen pairing especially effective for curl bounce and silkiness.
# Bottom line Topical hydrolyzed collagen functions as a surface-conditioning protein: it deposits peptides that temporarily smooth and strengthen the hair fiber and add hydration to the scalp. For people with dry, heat-stressed, or hard-to-manage hair, a finishing oil like Gisou's Honey Gloss Collagen Drops can provide immediate gloss and softness. Use caution if you have low-porosity or protein-sensitive hair and apply sparingly.
# Practical tips
- Apply the drops as a finishing oil after styling to avoid weighing hair down.
- Pair collagen-infused finishes with hydrating cleansers and masks rather than protein-heavy treatments.
- Consider the product if you want instant shine and smoothing rather than structural repair.
