Product Insights
Syoss Oleo 21 is a 100 ml hair‑care oil packaged in a bottle, marketed to smooth and add shine to hair. Its formulation blends lightweight carrier oils with vitamin‑rich argan oil and a fragrance blend that delivers a pleasant scent, while also containing silicones that help seal the hair cuticle. The presence of fragrance and silicone may irritate very sensitive scalps, so users with fragrance allergies or extremely dry, damaged hair should test a small amount before full application.
