“The glue is not strong. I've been wearing Keratin tips for 8+ years and I have to say that the glue on these are the worst I've ever had. I've had about 10-15 already come out. The hair itself, absolutely beautiful. Have to say it's probably the best I've ever had. It's a coin flip, not sure if it's really worth the price if they keep coming out & I have to keep putting them back in, if it's not one that got lost.”
