                            I really wanted to love this, but I will be returning. I have medium length, colored, thin blonde hair. After all the amazing reviews, I had to buy this. I hate it! It did absolutely nothing for my hair! The following morning my hair was very dry, and hard to comb.

                              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.

                              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.
