Our sew-in extensions can be waved, flat-ironed, curled, straightened, and even dyed just like you would your own hair.

They can also be bleached , but remember that by bleaching you will greatly reduce the length of the hair, so we always recommend when in doubt to choose a slightly lighter color and darken it with a simple color bath if you wish, it would always be a better option than bleaching. However, most of our clients do not need to dye their hair because we offer a sufficiently wide variety of colors.

This way you can experience for yourself which of the two options best suits you.

Some disadvantages of sewn curtains are:

10. CAN I USE CURTAIN EXTENSIONS ON SHORT HAIR?

Sew-in extensions can be placed on short hair. But you will need at least 10 cm to be able to place them without them being noticeable to the naked eye and so that the jump in hair length is not too abrupt and thus achieve an imperceptible hold.

Sew-in extensions do not damage the hair if low-quality glues are not used. Therefore, anyone can use sew-in extensions , even if they have fine and delicate hair, and if it is the first time they are used.

However, people with serious hair loss problems should not use any type of extensions until their condition improves.

Also when installing on short hair, keep in mind that you will need more extensions to achieve a reasonable volume effect. If it is very short hair you will need at least between 150 and 200 grams of hair to achieve the desired volume effect .

11. PLACING THE SEWN CURTAIN EXTENSIONS

Curtain placement is the only system that allows different placement methods. You can place them with rings, braided, sewn, with glue, and even with clips.

Here is a video tutorial on how to place them with the afro braiding hair method:

  • STEP 1 : You will need to do the preliminary work of braiding all your hair at the roots close to the scalp.
  • STEP 2 : Starting from the bottom, measure from end to end of your head and carry the first portion to place.
  • STEP 3 : Start sewing and knotting with the needle at one end, and continue making joints one finger apart.
  • STEP 4 : You should use a medium level of pressure when sewing, not too loose but not excessively strong to avoid unnecessary back traction.
  • STEP 5 : You can take the opportunity to place highlights of another color as you see in the video.
  • STEP 6 : Repeat the same operation, continuing to fill layers upwards, covering the entire back part up to the crown of the head.
