What it is
The Elizavecca Cer-100 Collagen Coating Hair Protein Treatment is a K-beauty intensive hair mask formulated with ceramides and hydrolyzed collagen to reinforce the hair's structural integrity from cuticle to cortex. It works by depositing a protein-rich film along the shaft, filling surface gaps that accumulate through chemical processing, heat styling, and environmental exposure. With over 63,700 reviews averaging 4.5 out of 5 stars, it has built a substantial track record among shoppers dealing with visibly damaged or weakened strands.
Who it's for
This treatment is best suited for hair that is chemically processed (colored, bleached, permed, or relaxed), heat-damaged, or generally prone to breakage, split ends, and frizz. It works across most hair textures — straight, wavy, and coily — particularly where porosity is high and the cuticle layer has been compromised. Those with fine or low-porosity hair should use it sparingly: protein overload is a real concern, and applying a heavy treatment too frequently on fine strands can lead to stiffness or brittleness over time. If your hair currently feels hard, straw-like, or snaps easily even before any chemical damage, it may already have excess protein and would benefit more from a moisture-focused mask instead.
How to use it
Apply to clean, towel-dried hair after shampooing. Section the hair and distribute a generous amount from mid-length through the ends, which are typically the most porous and damaged zones. Avoid applying heavy protein treatments directly to the scalp, as buildup can clog follicles and weigh down roots. Leave on for 5 to 20 minutes — a processing cap or gentle heat can help drive the product into the cuticle — then rinse thoroughly with cool water to seal the cuticle flat. Follow with a lightweight conditioner if your hair tends toward dryness, since protein treatments can leave strands feeling taut without an added moisture layer. For most damaged hair types, once every one to two weeks is appropriate; for fine or less-damaged hair, once a month is sufficient to avoid overloading the strand.
Key ingredients
Ceramides are lipid molecules naturally present in the hair's outer cuticle layer. When heat or chemical services strip them away, the cuticle lifts, causing frizz, tangling, and accelerated moisture loss. Replenishing ceramides through a topical treatment helps re-seal those lifted scales, resulting in smoother, shinier, and more manageable hair over repeated use.
Hydrolyzed collagen is a structural protein broken down into smaller peptide fragments that can adhere to and partially penetrate the hair shaft. It adds temporary tensile strength and elasticity, making strands more resistant to mechanical stress like brushing and styling. It also contributes to a fuller, more voluminous feel by slightly swelling the cortex, which is particularly noticeable on fine or flat hair.
Pros & cons
- Ceramide and collagen combination addresses both surface smoothness and internal strength simultaneously
- Highly rated across a very large sample of reviews, suggesting consistent real-world performance
- Rinse-out format makes it easy to control application frequency
- Works across multiple hair textures and damage levels
- A little product goes a long way, so the jar tends to last
- Protein-heavy formula can cause stiffness or brittleness if used too often on fine or low-porosity hair
- Requires a follow-up moisturizing conditioner to keep the protein-moisture balance in check for dry hair types
- Not a permanent repair — benefits are cumulative and require continued use to maintain
- The thick, cream consistency can be difficult to distribute evenly on very coily or densely packed hair without sectioning
How it compares
If scalp health is also a priority alongside strand repair, pairing this treatment with a tool like the HEETA Scalp Massager Shampoo Brush during your shampoo step can improve circulation and product distribution before you apply the mask. For those whose damage is less severe and who need ongoing maintenance rather than intensive repair, a lightweight leave-in option like Mielle Organics Rosemary & Mint Strengthening Hair Oil provides daily nourishment without the protein load — a useful complement between mask sessions rather than a direct substitute.
The verdict
The Elizavecca Cer-100 Collagen Coating Hair Protein Treatment is a well-formulated, purpose-built mask for hair that has taken a beating from bleach, color, heat, or mechanical stress. The ceramide-and-collagen combination is grounded in sound cosmetic science, and its strong review record across a large user base reflects a product that delivers on its core promise. The main caveat is one that applies to all protein treatments: more is not always better, and anyone with fine or low-porosity hair needs to monitor frequency carefully to avoid tipping into protein overload. Used at the right cadence with a complementary moisturizing conditioner, this is a reliable weekly or biweekly treatment for restoring strength, reducing frizz, and improving overall manageability in damaged hair.
What shoppers say
Shoppers with heavily damaged, over-processed, or chemically treated hair consistently report dramatic softening and reduced breakage after just a few uses. Many describe it as a reliable repeat purchase that rescues dry, fried-looking perms and curls, restoring shine and manageability without weighing hair down.
The main caveat worth noting is texture: once dry, some users notice a slightly gritty, grip-heavy feel rather than a silky finish—a trade-off that curl and wave enthusiasts tend to welcome but straight-hair shoppers seeking a smooth, sleek result may find unexpected.
I’m back to buy this again and thought I should probably leave a review as I don’t hardly ever double buy hair products. My hair has been over processed hard and was in bad shape. But really thought I was going to have to do a big cut and this stuff single handedly saved my hair. I use it twice a week in place of conditioner and once every so often let it sit for longer time before rinsing. This stuff is MAGIC. My hair is soft, shiny and healthy and it looked like hay before.
Read on Amazon ↗This stuff is a lifesaver for permed or naturally curly hair. My son’s perm was looking pretty fried/dry, and this completely turned it around. The Texture: It has a slightly gritty, "lived-in" feel once dry—which is great because it gives the hair some grip and "tooth" without being crinkly, crunchy, or stiff. It still has plenty of movement. How we used it: Applied to damp hair, then used a blow dryer on the no-heat setting. Why it’s a win-win: • Hybrid Product: It holds the style like a high-end curl cream but it’s actually a repairing conditioner. • The Scents: Very clean and not overwhelming (important for teens!). • The Price: Really affordable for the results you get. Teen approved and mom approved. Check out my before, during, and after pics to see the definition it gives!

Review: Elizavecca CER-100 Collagen Ceramide Coating Protein Treatment The "Holy Grail" for Damaged Hair? If you’ve spent any time looking for affordable hair repair treatments, you’ve likely seen this quirky packaging. The Elizavecca CER-100 has gained a cult following for being a budget-friendly alternative to high-end bond-repairing masks, and after trying it, it’s easy to see why. Key Benefits • Instant Softness: The combination of collagen and ceramides works quickly to smooth the hair cuticle. Even after one use, hair feels significantly less "crunchy." • Deep Hydration: It’s a protein treatment that doesn't leave the hair feeling stiff. Instead, it provides a silky, "glass-like" finish that makes brushing much easier. • Texture: The cream is thick and rich, meaning a little goes a long way. It clings to the hair strands without dripping everywhere while you wait. This for me the best my hair is dry and spent money is expensive creams and this is what my hair appreciates and needs economic and it is the best I love it the first one is over and I bought another one because it is really the best
Read on Amazon ↗Dec. 15, 2025, initial review: I received the Éclat Vitamin C serum and cream one week ago. It’s been a great addition to my routine. I’m 59, my dad was a dermatologist. I’m big into skincare and only use products backed by science. I like the consistency of the serum. It’s like water, so it mixes great with The Ordinary Buffet with Copper Peptides and Growth Factor serums. Apply mixed in a bottle, your hand or one at a time. All formulas compatible to do either. Next, I add my Rx Retin-A 0.05% to the Vitamin C cream, so it’s easier to spread the Retin-A (tretinoin). This is so perfect. They are ideally compatible. So far, no burning, redness or peeling with the added Vitamin C products. Make sure you treat your face, neck, chest and hands exactly the same, so none of them give away your age! My goal for the added Vitamin C is to even out my skin tone. I have very minimal sun damage. I haven’t tanned since 10th grade. But, we can always improve our skin tone and texture. The cream is a velvety smooth gel-cream texture, which is fabulous. It’s unscented, also good. The serum dries quickly, absorbs easily, as does the cream. No greasiness or oiliness during the day or breakouts. I use It Cosmetics powder foundation and Maybelline Age Rewind concealer. Both are great and compatible with all the products mentioned, and all available on Amazon. I will update review with results after I finish the first bottle and jar, then again in 3 months and 6 months. Be mindful of sun exposure when using Vitamin C, Retin-A or anything that increases cell turnover, so you don’t get burned, accidentally. I prefer sunscreen with clear zinc, and/or mineral barriers, rather than chemical sunscreens. I think Éclat products are very well formulated and reasonably priced. Results TBD!
Read on Amazon ↗This product is AMAZING!!! No need to spend a lot of money on products when you have this in your shower. I have bought this over and over again. It is a staple! It leaves my hair soft, not frizzy, and helps with breakage! Also this seller is awesome!! Always sends right away and super to work with!

Elizavecca Cer-100 Collagen Coating Hair Protein Treatment: frequently asked questions
How do you use Elizavecca CER-100 Collagen Coating Hair Protein Treatment?
Shampoo your hair first, then towel-dry so it's damp but not dripping. Apply CER-100 generously from mid-lengths to ends, comb through for even distribution, and leave on for 10–20 minutes. Rinse thoroughly with lukewarm water. For deeper penetration, sit under a hooded dryer or wrap hair in a warm towel during the processing time.
How long should you leave CER-100 on — and can you leave it overnight?
The standard leave-on time is 10–20 minutes, which is sufficient for the ceramides and collagen to coat the hair shaft. Leaving it overnight is generally not recommended — extended contact with a protein treatment can cause protein overload, leaving hair feeling stiff, brittle, or overly hard, especially if your strands are already protein-sensitive.
Do I need conditioner after using CER-100?
CER-100 functions as a treatment-conditioner hybrid, so a separate conditioner isn't strictly necessary after rinsing it out. However, if your hair tends to run dry, a light leave-in conditioner on the ends can help maintain moisture balance. Alternating protein treatments with hydrating masks is a smart long-term strategy to avoid dryness.
How often should I use Elizavecca CER-100?
Once every 1–2 weeks is a reasonable starting frequency for most hair types. Fine or low-porosity hair can reach protein saturation faster, so starting with once a month and monitoring how your hair responds is wise. Signs of overuse include crunchiness, reduced elasticity, or increased breakage — scale back if you notice any of these.
What types of hair benefit most from CER-100?
CER-100 is particularly well-suited for chemically processed, color-treated, heat-styled, or bleached hair that has lost its structural integrity. The ceramide and collagen blend helps reinforce the hair cuticle and reduce porosity. It's less ideal for hair that's already protein-sensitive or naturally very coarse and healthy, as those strands may not need the extra reinforcement.
Can too much protein treatment damage your hair?
Yes — protein overload is real. When hair receives more protein than it can absorb, it can become rigid, snap easily, and feel straw-like rather than strong. Balance is key: pair protein treatments like CER-100 with moisturizing sessions. If you also use styling tools frequently, a nourishing oil like Moroccanoil Treatment Hair Oil between treatments can help maintain softness.
Is Elizavecca a reputable Korean brand?
Yes, Elizavecca is a South Korean cosmetics brand known for affordable K-beauty hair and skincare products. The CER-100 line has a loyal following among the DIY hair-care community in the US, particularly for its accessible ingredient profile. It's a budget-friendly entry point into protein treatments, though results vary depending on individual hair condition and porosity.
