    Comments about Living Proof Perfect hair Day (PhD) Night Cap Overnight Perfector:

    This night cap was highly recommended by Jennifer Aniston and her hair always looks so shiny and healthy. So I bought this product believing and having high expectations. I put the product on my hair and put it on a loose bun, got up in the morning washed it with Living Proof timeless shampoo/conditioner and let it air dry.....and guess what? My hair was beautifully radiant, the curls were defined and so soft. My hair looked like it did when I was 25 years old....AMAZING!!!

      I went to far and damaged one side of my hair terribly! I can't believe the difference this night cap makes. I have heavy, thick wavy hair- and lots of it. It takes only a small amount of product to produce beautiful, shiny hair that shows no damage. Where has this been all my life! I've tried Argan oil, coconut oil, all the pricey bells and whistles- but NIGHT CAP does it. It's not "weighty" or heavy. Easy to use..and ....WALLAH!

        Comments about Living Proof Perfect hair Day (PhD) Night Cap Overnight Perfector:

        I love this product! I have gotten it a few times as samples (1oz and they tend to last over a month each) and finally decided to buy a full size and I do not regret it! It put about 3-4 pumps all throughout my hair after towel drying and from there let my hair air-dry on it's own. It leaves my hair super soft, shiney and manageable. I have naturally unruly hair and this saves the day! I'm also starting to notice that it helps my hair to dry faster than it usually would.
        Highly recommend!

                              My hairdresser says that night cap helps your hair grow longer, because it protects the ends and you don't need to cut it as often. Does it have this effect?

                                Night Cap Overnight Perfector is conditioning therefore it can be helpful for dry ends, which can lead to split ends. If you are looking for a product that helps repair dry, damaged hair and you want to prevent split ends I recommend using Restore Instant Repair.

                                Yes, you can layer the products! It is preference on how you use the treatment. As it is a conditioning treatment leaving it in for a longer period of time can have great outcomes and is not harmful to the hair!

                              I use living proof shampoo and conditioner and then a styling serum before I dry and flat iron my curly frizzy hair. Do I just add this at night, or do I eliminate one of those ( the serum?).

                                Because it is intended to be shampooed out, Living Proof Timeless Pre-Shampoo Treatment is more conditioning than Night Cap and also contains color, UV and thermal protection.
