CER-100 is Elizavecca's hair care series. Its main product, the hair mask CER-100 Collagen Ceramide Coating Protein Treatment, lists ceramide NP at 10 mg and hydrolysed collagen at 100 ppm, alongside hydrolysed silk, keratin and wheat, soy, corn and oat proteins. The brand recommends it for hair that is often coloured or permed, often blow-dried or styled with a flat iron, coarse and dry, or curly and prone to breaking. CER-100 Collagen Coating Hair A+ Muscle HellTornado Shampoo is, in the brand's words, a scalp shampoo: menthol and tea tree oil give a cooling feel, and the brand recommends it for oily scalps. CER-100 Hair Muscle Essence Oil contains no collagen or ceramide; the brand highlights argan oil and five other plant oils in it and suggests applying two or three pumps to towel-dried ends after washing. The brand's own order for the series: shampoo, hair mask, drying, then a leave-in "ion injection".
