The Elizavecca CER-100 Collagen Coating Hair Protein Treatment is a rinse out hair treatment from the Korean brand Elizavecca, listed on Amazon in a 100ml size. This is an editorial overview built from the current Amazon listing and the published product specs, not a hands on review. Nothing here comes from first hand use, so everything below describes what the listing states and how a rinse out treatment like this is intended to be used, rather than results we observed ourselves. If you are weighing it up as an affordable conditioning step for a wash day routine, here is a clear, honest look at what it is, who it may suit, and what to confirm on the listing before you buy.
What it is
CER-100 is sold as a cosmetic rinse out hair treatment. In practice that means it is a product you apply after shampooing, leave on the hair for a short time, and then rinse away, rather than a leave in product or a daily styling cream. The listing presents it in a compact 100ml tube, which places it in the small, occasional use category rather than a large family size tub.
The words "Collagen Coating" and "Protein Treatment" in the name are the brand's product and marketing language. They describe the cosmetic idea behind the product, which is coating the surface of the hair so it feels smoother and more conditioned. They are not medical or clinical claims, and they should not be read as promises to repair, regrow, or permanently change the hair. Treated as what it is, a cosmetic conditioning rinse, it sits alongside masks and conditioners as a periodic step you can add to a routine.
Key features
Based only on what the listing and specs state, the headline points are simple. It is a rinse out format, so it is used in the shower and washed out. It arrives in a 100ml size, a small tube that suits trying a product or keeping one for occasional use. It is marketed as a collagen and protein style conditioning treatment, language aimed at people who want their hair to feel softer and more manageable after washing. And it comes from Elizavecca, a Korean beauty brand with an established following for budget friendly hair and skin products.

Check price on AmazonWho it is for
On paper this is aimed at people whose hair feels dry, rough, or damaged after coloring, heat styling, or general wear, and who want an inexpensive conditioning treatment to slot into their routine now and then. If you like a quick rinse out step rather than a long sit with a heavy mask, the format is convenient. It may also appeal to anyone curious about Korean hair care who wants to try a widely available, budget conditioning treatment without a large commitment of money or shelf space.
It is less likely to suit someone looking for a professional strength, long term solution, or anyone expecting a product to fix a medical scalp or hair concern. For those situations a cosmetic rinse is not the right tool, and a qualified professional is a better starting point.
Strengths on paper
The clearest strength is accessibility. A small 100ml size and a simple rinse out routine make it a low commitment way to try a conditioning treatment, and the brand is easy to find on Amazon. The format is also beginner friendly, because there is nothing to leave in or style around. You wash, apply, wait, and rinse. Because this overview is not based on first hand use, these are strengths as described by the listing and the format rather than performance we measured, and your own hair type and routine will shape how useful any conditioning treatment feels.
Things to check
Before buying, confirm a few practical details directly on the Amazon listing, since formulas, sizes, and packaging can change over time.
Check the size or count. The listing describes a 100ml tube. If you wash often or have long, thick hair, decide whether that quantity matches how often you plan to use it.
Check how to use it. As a rinse out treatment it is generally applied to clean, towel dried hair, left for a few minutes, then rinsed out, but you should follow the exact directions printed on the listing and packaging rather than a generic routine.
Check the ingredients. Read the full ingredient list on the listing or the package, especially if you have known allergies or a sensitive, reactive scalp, so you know what you are putting on your hair.
Do a patch test. If your scalp is sensitive or you react easily to new products, apply a small amount to a discreet area first and wait to see how your skin responds before using it fully.
Remember it is cosmetic, not medical. This is a conditioning product for how the hair looks and feels. It is not a treatment for hair loss or any medical condition, and the collagen and protein naming is cosmetic marketing rather than a clinical claim.
Verify everything on the listing. Treat this overview as a starting point and confirm the current size, ingredients, directions, and brand details on the live Amazon page before you decide.
How it compares
It helps to frame this as a budget protein style treatment rather than a salon service. An inexpensive, at home rinse out like this is designed for occasional, do it yourself conditioning, and it is judged on convenience, feel, and value for a small outlay. A salon protein or bonding treatment is a different category, a professional service applied and monitored by a stylist, usually stronger, longer in process, and far higher in cost. Neither is a substitute for the other. If you want a simple step you can run yourself between washes, a budget rinse out fits that job. If you want professional strength work on heavily processed hair, that belongs in a salon chair. Setting that expectation upfront keeps any comparison fair, and we are not naming specific competing products here because the honest comparison is really about the category and the use case, not a head to head between two bottles.
Verdict
If you want an affordable, straightforward rinse out conditioning treatment and you keep your expectations cosmetic, the Elizavecca CER-100 is a low risk, low commitment option to try, thanks to its small size and simple routine. It is not a repair miracle or a medical product, and it should not be bought as one. Treat it as a periodic conditioning step, confirm the size, ingredients, and directions, patch test if your scalp is sensitive, and you will have a realistic picture of what you are getting. When you are ready, check the current listing on Amazon to confirm the current details and decide for yourself.
