My hair is color damaged, plus naturally dry to begin with. I was my hair once a week and I use this on the 3rd day to refresh. When I wake up my hair is so silky and beautiful!!!

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

My hair used to be very dry and damaged. I've been using this for the past year and my hairdresser commented today on how healthy, soft, and manageable my hair is. I put this on every Sunday night to damp hair and let it air-dry. I style as normal the rest of the week.

      I only have a sample of this product and it changed my life. I have the worst bed head imaginable—like to the point where I wonder if a ghost teases my hair in my sleep. Brushing out my birds nest every day makes my hair break and look like I've been electrocuted. I used this as a hair mask and washed it out the next day and OH MY GOODNESS. My hair is soft and touchable and I have NO bed head. This is a miracle and you need it. My hair was dry and felt like straw and now it feels like silk. I am blown away.

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

        I had my hair colored twice in one week (didn't like the first bayalage I had). This included lifting a darker color I had towards my roots and lightening my blonde. As you can imagine, my hair wasn't so happy. Even my scalp was tender. I had a sample of this lying around, I had got it a while back but hadn't used it. Slathered it all over my hair, from root to tip, and left it on overnight. Woke up the next day, took a shower but didn't shampoo my hair, just conditioned it (DevaCurl One Condition Delight) and my hair is already so much healthier! It was shiny, smooth, detangled, and easier to style. Now I'm purchasing the full size to have on hand as a weekly treatment. Great stuff.

        I've tried a few Living Proof products and didn't love them all, but the Nightcap Overnight Protector is awesome. I usually wash my hair right before bed, and I work some of this into my hair after I've dried it and before I put it in a ponytail. When I blow out my hair the next morning to refresh it, the Overnight Protector makes it very soft. Great product. I'm on my second bottle. It's pricey, but worth it.

            I have straight hair and don't wash it every day, as I'm prone to dryness. However, my #1 concern is making sure that my hair looks fresh for the second day before a wash. I usually have kinks from sleeping that even a hair straightener can't fully get out. I had a sample of the Living Proof PhD Night Cap Protector, and I didn't think it was effective. However, I've been using it as I go to bed at night and WOW, my hair looks ready to go as I get out of bed in the morning! I'm sold, and I love it.

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

              I got a 1 oz sample of this product and I am obsessed with it. Whenever I go to bed with my hair wet I wake up to a frizzy mess. When I use just a dime size amount of this product in my wet/damp hair before bed I wake up with smooth, soft hair that looks like I took the time to style it! My hair is very thick, long (butt length), and wavy. I am always on the hunt for that product that will keep the frizz away. I've tried a ton of products and I have finally found the secret weapon! I only wash my hair once a week and this stuff doesn't leave any build up, doesn't make my hair greasy, and doesn't weigh my hair down. I start halfway down my hair then work up putting barely anything on my roots. I'm cheap with hair products, but I will gladly shell out the money for this miracle product! It saves my hair from the blow dryer, straightener, and curling iron during the week so my hair is getting healthier because of it. Buy this product if you want to wake up with ready to go hair!

              • Q:

                I have been using this product for quite a while. I was using it after washing my hair to tame it - like a strong version of the 5 in 1. The last two bottles I've purchased have been more liquid and do not work as well and don't even come out of the bottle properly. The lady I spoke with at Ulta seemed to say it must have expired. I believe I bought one bottle in the store and ordered one online so it is unlikely that they were both expired. Has the formula changed?
                I want something oil free that WILL weigh my hair down. Would the Timeless Prewash be thicker?

                  A:

                  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.
