what types of hair extensions are there?

Ive had bonded extensions twice in the past and I know they're not the greatest. Can fall out, a lot! Be expensive to keep maintained and also make you loose some of your real hair! I know the ups and downs having experienced most of them myself lol. I don't like clips in, the clips give me bad headaches and I don't like having to take them in and out all of the time, don't have time for that. So clip ins will not do (sassy!) Lol. But I dont know what other options are out there? I'm in the UK so options may be different here to the U.S. But I'd still like to know. Thank you ladies! 💆💇💁
