For closure, We have 4*4 closure and 13*4 frontal closure. And I suggest you can buy hair weft with closure together. It looks more natural! 

For hair wefts, 3pcs for 10-22inch, 4pcs for 24-30inch. If you want to get a very full look, you might need another pack. If you are getting fusion or micro then you will need to consult your stylist.

Treat this hair just as if it was your own hair.

1. Use good quality shampoo and conditioning products.
2. Conditioning your hair is very important to keep it soft and manageable, so use leave in conditioners.
3. You could use gel or hair spray to keep the curls in place, but make sure to wash your hair and not leave in these products in for a long time.
4. Olive oil will be a good choice to keep the hair healthy.

This hair can last for a very long time depending on how you maintain it. Treat it like your own hair and take very good care of it for it to last longer. If you take good care of the hair, it last for over one year.

Yes. Please have a professional color your hair for you can over process your extensions.

You may go in swimming pools and hot tubs. It is best to wash hair right after swimming. Avoid getting hair in salt water as the salt can take all the moisture out of the hair and it will lead to tangling of the hair. Never braid your hair and go in salt water. It is best to wear it down. Add a spray in conditioner after swimming.
