Kerastase Elixr Ultime Hydrating Hair Oil Serum. Never used, comes in a 100 mL glass bottle (I don’t have original box sadly). This hair oil was on my Christmas list, I ended up purchasing it for myself and then got another bottle from a family member, so I can say that this hair oil smells amazing and is super lightweight, almost like a dry oil, and the packaging is beautiful💛 currently on Sephora for $58, but offers are welcome.
