just twist and crack the seal and it will slip off

How long have you had them in?

they didn't work for me either and came out easy

Hey, that is too bad that the heat seals don't work for you guys. 

Amethystkat, I lost about 15 at first, maybe w/in the first 10 days,  and then it slowed to about 1 per week for the remaining 10 weeks.  I can understand how they'd be hard to wear w/ oily hair, though.  Could you try to wash just your head every day, holding the rest of the hair out of the way?  I found some good hair washing tricks here, maybe you've seen them.  I also read that someone suggested dabbing Seabreeze on the scalp between washings. 

Or is it that you feel like too many ext are slipping out b/c of the oilyness?

They are fairly easy to remove, it is just time consuming.  I cracked the seal and w/ a lot of them, I had to really get in there and pick off the melted plastic. 

I agree, they are high maintenance...

(but I have to add that the extra care they required was well worth it to me)

if its not blending go back to whoever did it

i looked at the pics and it looks good to me. has it changed now?

it seems a shame to take them all out you could tie the top bits back in a pony taking a bit of the extension hair from underneat thats what i do when i have blend issues at the top.

is it a difference of texture or colour?

hmmm - well i guess amethyst if you are unhappy then you are unhappy, but what i can address is the oiliness issue -

i myself had an oily oily scalp - so oily that i'd wash in the am and by the pm my hair was greasy greasy. god forbid if i skip a day -gross. when i started messing around with extensions and got pinchbraids for the first time i made myself start lengthening the time in between washing. i swear to you your scalp will adjust. it will take time, and you may feel greasy...but it is worth it and i can't tell you how nice it is to wash my hair once a week. that's it - i can wash more if i want but i don't need to. pace yourself and start off by washing every other day..then every three days...etc etc. use talcum or another powder on your scalp as kirsty suggested and try a vinegar rinse (10% diluted in water) when you do and it will cut down the grease.

reducing my washing has lead to a healthier scalp, healthier hair, less time grooming, and helps my extensions live longer as well as lets my color last longer. i would really encourage you to try this because extensions or not your scalp will reduce it's oil production if you aren't giving it a reason to produce oil by washing frequently.

hope this helps.

you need to trick your hair folicles into thinking your hair is oily-

what i mean is this-

if you wash your hair everyday and your hair is already oily- then the washing everyday tends to "Try" to make your scalp dry- if even only for the day- so it sends a signal to the oil producing glands that your hair is dry and now u need more oil.

so if you do what cccross suggusts by not washing so much, you will trick your shcalp into thinking- ok i dont need anymore oil for now. it may take some time but it could owrk-

this goes the same for women who scrub their face dry everynite when they have oily skin, they get oilier skin and and more breakouts from trying to get the oil away.

hope this makes sense.
