don’t change your curler. My problem was that when I curled I used a little bit too much hair, so I just used a little less and now they stay for a long time, like untill I wash my hair again. I don’t even use hairspray, just make sure that yoou have heat protection in your hair and you’re good to go!

Hope I helped!

try going to a nice salon get a free consultation from someone good with an iron.pay attention to there technique.
see how long this lasts.if you cant hold a curl with a Professional iron you probably wont hold one at all.but if it does hold you know its the iron you need.
i usually don’t need allot of products just my good iron to curl hair and not everybodys hair can hold no matter how much spray you use.
good luck
peace
