Ouidad Curl Immersion Triple Treat Deep Conditioner ($38; sephora.com) is a super rich, deep conditioner for wavy/curly or dry hair that needs a quick moisture boost. Its quite a thick consistency with an ultra creamy texture. I use it like would any other deep conditioner, after shampoo, leave it on for a few minutes and wash off. Its a lovely one to use after a clarifying shampoo and perfect if you have wavy hair that gets frizzy with the slightest amount of humidity. The scent is quite strong and lingers on for a bit, but it is quite an easy mask to wash off. I do think it can weigh hair down if you have fine hair or if your hair gets weighed down by heavier products that penetrate, but that apart, its a really nice deep conditioner to try maybe once or twice a week if you have normal wavy hair. I generally skip a styling product when I use this and if you use it more than twice a week, be sure to have a clarifying shampoo handy.
