I have VERY dry hair so I tend to buy a lot of conditioning products that are meant to moisturize my hair, some are daily conditioners and some a deep treatments. The Elasta QP DPR-11 is a deep penetraining remoisturizer that I use in my deep treatment rotation to keep my hair soft, tangle free and moisturized!
I purchased a 16oz tub of this conditioner. It doesn't come in any other size. What I like about this deep conditioner is that it contains 11 plant extracts, essential oils and vitamins, in addition to moisturizing emollients (for strength and elasticity), peach blossom oil and vitamin E. It is thick and not runny. The colour is a light orangey-peach and the smell isn't the greatest (kinda fruity-chemically smelling) but it works great!
I put this on my dry hair, and a lot of it, then put a shower cap. If I'm not going anywher I'll just wear the shower cap all day, but if I want a quick deep treatment I'll use my heated conditioning cap for 30-45 minutes. Then I rinse it out in lukewarm to cool water to help seal my hair's cuticles. This deep conditioner rinses out very easily and I am left with soft, tangle free and moisturized hair. I also use this on my daughter's hair with the same great results.
