A serum is a product with a promise. It promises a shot of something. It could be nutrition, hydration, radiance... This one, Sachajuan, is a multipurpose serum: it adds glow (not greasy) to the hair, seals split ends, and this is good in substance and form, prevents damage that hair suffers daily from factors such as pollution, diet, lack of sleep... and it works as a product of base for any subsequent hairstyle.
It's a professional treatment that can be done every day at home. It's a product designed for damaged hair, which is almost the majority. It also contains technology called Ocean Silk, a nutritious mix of extracts seaweed (such as Rhodophycea and Chondrus Crispus) that They're key to keeping hair hydrated, its cuticles closed, and its shine and body. And all thanks to algae. It's a product that promises what it delivers. We've been loving it for years.
