Review (1/5): Do not recommend!
A few slipped completely out a couple days after installing (correctly, I’ve done this before), before I’d even washed my hair with them in. Then they all started to slip further away from my scalp. When I tried to remove them with remover oil (after a week or two, because they were slipping), they left a sticky mess in my hair, and completely ruined my extensions and I lost gobs of natural hair. Very upsetting.
