1) With weft, the weft process is done before the curls are formed and there is a dense amount of hair on track to create a uniform curl!
2) Closures, on the other hand, are done after the curl to avoid the root being straight! They are also done strand by strand hence the curl is slightly more unruly which makes it natural! You will notice defined curls towards the middle and tip of the hair as the hair come together. Also, the texture is generally looser due to stretching during the closure ventilation process.
3) Also, you must know all our hair is made from 100% virgin hair; the only process we do is add the curl. Virgin hair exhibits certain characteristics: some will be silkier, some will hold curls better, some have a thicker diameter. All these will affect the result of the hair after we process the curl (done manually for a natural look) hence there is slight variation in the curl pattern.
To achieve more defined curls, you will need to:
i) Section the closures especially if you have a large closure. Just like you would section your natural hair for a more defiled curl!
ii) Make sure the hair is really wet with the moisturizing conditions to force the strands to come together and then manipulate the curls with a nice curly hairbrush.
iii) Scrunch it with a towel to induce the curls!
iv) Finally, let it air dry while scrunching at intervals. Do not separate the curls until it is almost dry.
v) You can further induce curls with a diffuser.
vi) Another helpful tip if you feel the texture is slightly different, try sewing in one or 2 tracks of the weft (preferably split version) inside the closure for better blending. This is not necessary, but some customers do so.
