Hi Yann ... it`s expensive, but you`d most likely get a lot of attachments from one bottle..... I`d be interested to hear about the results you get from it if you decide to try it out...
My own scalp can be very oily, which is another reason I go for a nightly removal...I always give the scalp a wipe -over with a cotton pad soaked in alcohol...that ensures a really clean ` foundation ` for the new attachment. The thing you have to be careful with, when using acrylic glues is not to try to remove the ` excess` glue from the applicator by wiping it on the side of the container --- dip the applicator into the glue and then hold it above the bottle so the excess glue runs off naturally into the bottle..... if you ` wipe` the applicator on the container, you get long, very fine ` threads` of glue which can then get stuck to the hair and generally every place you don`t want it !!!! You need to be patient when using acrylic glue and as always , ensure you apply it thinly to your scalp and allow each coat to go practically dry before applying the next.....if ` wet` glue gets into the lace it will seep through and solidify around the base of the hairs, forming ` clumps` ...this is a nightmare to deal with !!
