Can anybody recommend a defrizzing product for thick hair that a) actually works and b) won't break the bank? I've got argan oil from Poundland but I don't like it making my hair feel greasy. I've tried various serums and suchlike over the years but none of them really seem to work very well. The No Oil Hair Oil was OK, but I've lost it :( and it's pretty expensive even if it does last for ages...
Any suggestions? Thank you!
