I am a hairdresser and this is my review and what I think people should know/do. The packs of hair are the fullest I have seen for the price, meaning at the bottom, the hair is not scraggly and thin, it is a nice full length strip with a blunt cut. But they are thin individually. Get more than you would usually get. Secondly, hair extension typically have some type of coating on them, that's why they are so silky...and thin. I wash mine upon arrival, KEEP YOUR TAPES DRY. I also gave my extension hair a treatment of Paul Mitchell PM shines clear and Olaplex. I have found over the years, putting a demi permanent color on my extensions keep them sealed, soft and shiny. It also, in my opinion, reduces the extensions from making my natural hair dry. You can also install your extensions and then after a couple of days, put a DEMI color, not permanent color, over your hair and the extensions. Try not to get it all over your tapes. Do not get conditioner all over your tapes. Do not get oils all over your tapes. It will dissolve the adhesive and your extensions will come out. Also, do yourself a favor and order extra tape or grab a pack from Sallys...you will need it if you lose an extension and need a quickie repair. I think these are decent extensions for the price, but like anything take care of the hair, or IT WILL MATT OVER TIME. You need to pony tail or braid them if they are really long when you sleep. Comb them from the bottom if they tangle, and lastly get yourself good shampoo and conditioner. I have not installed these yet, so my only concern now is the tapes, and that can be remedied with decent hair. Remember for retaping, you tape on top of the old tape, do not try to remove the first layer, they will fall apart. Most hair can be retaped and installed again up to 3-4 times if the hair is cared for. Good Luck! Cheers to great hair days!Update: I have had my extensions in for 2 solid weeks. They are great! Remember, install on really clean hair with no oily product on your hair. I shampoo every other day, but they are so well glued, I could probably shampoo daily with no issue. I braid them when I sleep to avoid frizz, and they are still shiny and soft. I did do pre treatments as stated above, but these extensions still look great with very minimal hair loss. I really like that they are not super straight. I can let them air dry and they have a little wave to them, but blowing them dry, they can be straight easily. I will suggest if your hair is naturally thin, get 2 packs of hair and some single sided extension tape! That way the hair goes further and you do not have so much thickness.
