You’ve probably heard a lot about collagen, but most of the conversation has centered around skin care. What most people don’t know is that collagen is also responsible for helping hair (not just skin) to maintain strength and elasticity. The new Vichy Dercos Collagen Peptide 17 collection is a three-step hair care system designed to help repair and strengthen dry, damaged and weakened strands, restoring fullness and resiliency. Whether you’re dealing with damage, dryness or breakage, this line is worth knowing about. In this blog, we’ll cover:

Is collagen good for hair?

Yes, collagen for hair is essential—and here’s why. Hair is primarily made up of a protein called keratin, and collagen plays a supporting role in the body’s ability to produce the amino acids that build keratin. As we age, the body’s natural collagen production begins to decline, which can show up as changes in hair texture, thickness and strength.

When applied topically through products like a collagen shampoo or collagen conditioner, collagen peptides work differently than ingestible supplements. They coat the hair shaft, helping to smooth the cuticle, improve elasticity and add visible body and bounce. The result is hair that feels stronger, looks healthier and is better protected against daily damage from styling, heat and environmental stressors.

The collagen benefits for hair you need to know

If you’re considering adding collagen-powered Vichy Dercos Collagen Peptide 17 hair care products to your routine, here’s a quick look at what you can expect:

• Improved strength and resilience: Collagen peptides help reinforce the hair’s structure from the outside in, making it less prone to splitting.
• Enhanced moisture retention: Collagen acts as a humectant, helping hair hold onto hydration for a smoother, softer feel.
• Added volume and thickness: By plumping the hair shaft, collagen can make fine or thinning hair appear visibly fuller.
• Smoother cuticle: A smoother cuticle means less frizz, more shine and easier detangling.
• Protection against damage: Strengthened strands are more resistant to the daily wear and tear that leads to breakage and dullness.

The Vichy Dercos Collagen Peptide 17 collection puts these collagen benefits for hair front and center, combining Vichy’s signature mineralizing Volcanic Water with a potent 17% collagen peptide complex for visible results.

Vichy Dercos Collagen Peptide 17 Ultra-Repairing Shampoo

If you’ve been searching for a collagen shampoo that actually delivers, this is it. The Vichy Dercos Collagen Peptide 17 Ultra-Repairing Shampoo gently but thoroughly cleanses while infusing hair with a 17% collagen peptide complex at the very first step of your routine. Vichy’s mineralizing Volcanic Water, enriched with fifteen minerals, supports scalp and strand health from root to tip.

It’s formulated for damaged or weakened hair and lathers into a rich, reparative cleanse that leaves hair feeling immediately softer and more manageable. Unlike a typical clarifying shampoo, this one works to build strength rather than strip it away. Use it as the foundation of your collagen shampoo and conditioner routine and notice the difference within the first few washes.

Vichy Dercos Collagen Peptide 17 Ultra-Repairing Conditioner

The natural follow-up to the shampoo, this collagen conditioner is where the real transformation begins to show. The Vichy Dercos Collagen Peptide 17 Ultra-Repairing Conditioner seals in the work done by the shampoo step, locking moisture into the hair shaft while continuing to deliver collagen peptides for strengthening and repair.

Applied from mid-length to ends, it detangles effortlessly while smoothing the cuticle for visible shine and reduced frizz. The collagen shampoo and conditioner duo works synergistically, with each step reinforcing the benefits of the other, so skipping one means leaving results on the table. For fine hair types who worry about conditioner weighing hair down, you’ll be pleased to know the formula is rich but not heavy.

Vichy Dercos Collagen Peptide 17 Ultra-Repairing Treatment

Consider this the concentrated dose of repair your hair has been waiting for. The Vichy Dercos Collagen Peptide 17 Ultra-Repairing Treatment is a targeted collagen hair treatment designed to be used as a weekly or bi-weekly intensive mask, delivering a higher level of collagen peptide concentration directly where damaged hair needs it most.

Apply it after shampooing in place of conditioner, leave it on for a few minutes and rinse to reveal hair that feels noticeably softer, more elastic and less prone to breakage. If your hair has been through chemical treatments, heat styling or environmental damage, this collagen hair treatment is the kind of weekly reset that can meaningfully shift the health of your strands over time.

How to use the collection for best results

Getting the most out of the Vichy Dercos Collagen Peptide 17 lineup is straightforward. Here’s a simple routine to follow:

• On wash days: Start with the Ultra-Repairing Shampoo, massaging into wet hair and scalp, then rinse thoroughly. Follow with the Ultra-Repairing Conditioner on lengths and ends, leave for two to three minutes and rinse.
• Once or twice a week: Swap the conditioner for the Ultra-Repairing Treatment. Apply generously, focusing on the most damaged sections, and allow it to penetrate for three to five minutes before rinsing.
• Consistency is key: Like any reparative routine, the results build over time. Commit to the full system for at least four to six weeks to see meaningful improvement in strength, texture and overall hair health.

Whether you’re trying to recover from overstyling, heat damage or simply the natural wear that comes with everyday life, the Vichy Dercos Collagen Peptide 17 collection gives your hair a fighting chance. It’s a smart, science-backed system rooted in one of the most talked-about ingredients—and now it’s earning its rightful place in the haircare conversation.
