I used to get a really lovely hair serum by Kerastase, the bottle was clear and there was orange writing / label on it. Any idea which serum replaces it? I had a look at [[https://www.lookfantastic.com/kerastase-elixir-ultime-l-original-hair-oil-100ml/11858060.html?out-of-stock-alternative this one]] and was wondering if it might be similar.
