not too bad [SEP] not bad there are several reviews saying the tape did not last long in their hair however that was not an issue for me at all i purchased the silver inch set my first hair extension application and it went well of course my husband had to helpwe watched a youtube video and applied the tape by sandwiching a small section of hair between each he also used the hair straightener which i think was the trick for lasting adhesion to squeeze the tape onto my hair for a few seconds for the most part they did pretty well i ve had them in for about months they don t handle washing very well so i tend to really condition the ends and need to trim them occasionally as they will fray a bit and break after a lot of styling for an inexpensive set i m not disappointed at all i was able to curl them as needed as seen in the picture will purchase a higher quality next time so i don t have to apply so much oil and conditioner to keep them soft
