I love the "nectar of nature" collection from Les Cosmétiques Design Paris. It's great. It smells delicious and comes in so many different fragrances, plus it's cheap for a big brand like that.
But for conditioner I usually use Franck Provost, Dessange, or Syoss, which is more epensive but just so much better quality, and my hair just looks/feels softer and shinier.
As for the mask I use "Kéra", by Les Cosmétiques Design Paris. It's so good.
And then for hair oil, I use L'Oréal's "Elvital", which I definitely recommend, because it's just AH-MAH-ZINGG.
