                 how to care for hair extensions?

    1. Brushing

    Get an extension brush. This is vital, you will literally rip your head of hair out if you try and brush them continuously with a normal brush, so seriously get one, they are only about $15 and worth every cent.

    2. Roots

    This is brushing continued you could say - because it is hella important to never brush your roots. Why? Because this is where your extensions are bonded to your head and you will damage them and potentially pull them out if you brush them. Instead, finger your hands through the roots to keep them from tangling and then hold your hair in a fist just under your ear and then brush the ends. By holding your hair you are taking pressure off the bonds, therefore, keeping them tight.

    get an extensions brush

    3. Shampoo

    Choose a natural or extension friendly shampoo. Stay away from any shampoo with Sodium Laurel Sulfate (SLS) as this often damages and corrodes the bonds.

    4. Washing

    When in the shower, turn the temperature to cold just before you get out and give your hair a blast of the cold shower, this will help keep your bonds once again nice and tight and close your pores too. *NEVER wash your hair over the bath as all the bonds will tangle. Always wash your hair standing up.Wash the hair with mild conditioning and shampoo in warm water, 2-3 times every week.

    5. Drying

    Always fully dry your bonds, you can leave the ends dry naturally if you want, but it is very important to keep the roots bone dry. Another tip is to put your hair dryer on the cold setting, as it is once again, you guessed it, better for the bonds.

    6. At night

    When sleeping, a very good tip I learned is to plait your hair before you go to bed, not only does this give your hair a fab beachy wave when you wake up, but it also keeps your hair from tangling. Success.

    8.Store Your Extensions

    When you’re not wearing your luxuries, store them away properly. L for P sells cute storage bags that can be hung in your closet. This will protect the hair from tangling up or getting mixed up with your belongings. The storage bag is also great for traveling.

    9. Hair spray or styling

    Hairspray is OK, just remember to properly wash it out the next day!

    The temperature during the crimping or straightening process needs to be lower than 180℃

    10. Itching

    When you get a new set of extensions, especially your first set ever, it is normal for them to feel a little itchy. Often it's just your head getting used to them and sometimes it could be because you need to give them a wash. Obviously, if itching persists, go to your hair technician but usually, it is normal!

    Why choose Virgin Hair?
    what is virgin hair


    What is Virgin Hair?

    • Virgin hair is directly taken from the human head and does not undergo any chemical alteration or cleansing process. It has to be 100% pure.
    • It cannot have gone through any kind of chemical processing, so when you purchase this hair, it has not been permed, bleached, blow-dried, gone through any other chemical processing.
    • It's from one single donor, so each bundle you buy should be from the same donors(the donor could be Indian, Malaysian, Brazilian, etc). This has not been exposed to any kinds of harsh agents and the cuticles all still have to be intact and running in the same direction.
